## Codex Project-Reference Loading (Hook-Independent)
Claude and Codex use static project-reference loading as the authority; hooks may accelerate discovery but never replace the explicit read.
When coding, planning, debugging, testing, or reviewing, open project docs explicitly using this routing.
**Always read:**
- `docs/project-config.json` (project-specific paths, commands, modules, and workflow/test settings)
- `docs/project-reference/docs-index-reference.md` (routes to the full `docs/project-reference/*` catalog)
- `docs/project-reference/lessons.md` (always-on guardrails and anti-patterns)
**Missing/stale context route:** If `docs/project-config.json`, the docs index, `lessons.md`, `CLAUDE.md`, `AGENTS.md`, or any task-required reference doc is missing or stale, auto-run `$project-init` or the narrow setup route (`$project-config`, `$docs-init`, `$scan-all`, `$scan --target=<key>`, `$claude-md-init`) before ordinary project-specific work. If Codex mirrors or `AGENTS.md` are missing/stale, ask the user to run `$sync-codex`; do not auto-run it.
**Situation-based docs:**
- Project structure/architecture/tech-stack/deployment/setup (any layer — backend, frontend, or infra): `project-structure-reference.md`
- Backend/CQRS/API/domain/entity changes: `backend-patterns-reference.md`, `domain-entities-reference.md`
- Frontend/UI/styling/design-system: `frontend-patterns-reference.md`, `scss-styling-guide.md`, `design-system/README.md`
- Spec authoring, `docs/specs/` pathing, or TC format: `feature-spec-reference.md`, `spec-system-reference.md`, `spec-principles.md`
- Behavior/public-contract changes or spec-test-code sync: `workflow-spec-test-code-cycle-reference.md` plus the spec docs above
- Derived spec indexes/ERDs/reimplementation guides: `spec-system-reference.md` and source Feature Specs under `docs/specs/`
- Integration test implementation/review: `integration-test-reference.md`
- E2E test implementation/review: `e2e-test-reference.md`
- Code review/audit work: `code-review-rules.md` plus domain docs above based on changed files
Do not read all docs blindly. Start from `docs-index-reference.md`, then open only relevant files for the task.

## Quick Summary
**Goal:** Validate UI/frontend changes for the six visual-quality dimensions that break in production but slip past correctness review — long-content overflow & truncation, responsive multi-screen layout (flex-wrap / row-to-column so it stays usable on small devices), flex-grow vs fixed sizing, z-index scale discipline, SCSS/CSS/BEM styling quality, and async UI states & feedback (loading indicator, user-visible error surface, empty state, in-flight disable) — so frontend/UI changes survive real content, responsive layouts, layering, styling conventions, and the loading/error/empty branches before handoff.
**Summary:** Review only the resolved frontend scope, apply project UI rules plus six UI categories and nine design-principles passes, then report evidence-backed PASS/WARN/BLOCKED findings through validated full-review loops.
**Default scope:** All uncommitted frontend changes (staged + unstaged) matching the frontend path and file-extension patterns declared by the project configuration/docs index. Override: specify files, directories, components, or full frontend codebase.
> **CONDITIONAL — SKIP when no frontend files in scope.** In workflow context this skill is SKIPPED when the diff has no files matching the project frontend path/extension patterns. If invoked standalone with no frontend changes → announce `"No frontend changes detected — ui-review skipped"` and report clean.
> **ROUTING BOUNDARY (read before starting):**
>
> - **`ui-review` (this skill)** — the project UI review gate. Purpose: find issues, assign severity, give project-specific fix guidance citing real reuse targets (sourced from the project reference docs). It complements `architecture-review`. In `workflow-review-changes` it runs in TWO places by design (keep both): (a) INTERNALLY as `changes-review`'s UI dimension (step 1), AND (b) as a DEDICATED conditional parallel-batch member (step 9, `ui-ux-designer` sub-agent). Both fire only when frontend files are in scope.
> - **`web-design-guidelines`** — a generic, standalone accessibility / UX checklist. Cross-read it for a11y depth (WCAG, focus order, ARIA, contrast); do NOT duplicate its content here.
> - **`ui-ux-designer`** — specialized UI/UX, accessibility, responsive layout, and design-token review/authoring sub-agent when the local agent catalog provides it.
> **MANDATORY MUST ATTENTION** Plan tasks to READ UI rules BEFORE reviewing:
>
> 1. Project styling rules doc — BEM convention, mixins, variables, responsive patterns **(READ FIRST — primary styling rules source; resolve via project config/docs index)**
> 2. Project design-system/token doc — design tokens, especially the **Z-Index & Layering** section
> 3. Project frontend architecture/patterns doc — base component classes, state/store, API service, lifecycle teardown rules shared with `architecture-review`
> 4. Project code-review rules doc — anti-patterns and conventions
>
> Not found → search: "scss styling", "design tokens", "frontend patterns". Rules come from docs — NOT general knowledge.
**Workflow:**
1. **Phase 0: Load UI Rules** — Resolve and read the four project UI/styling rule docs above
2. **Phase 1: Determine Scope** — Changed frontend files (default) or user-specified scope
3. **Phase 2: Blast Radius** — Run graph trace if graph.db exists
4. **Phase 3: UI Category Review** — Check each file against all 6 applicable categories
5. **Phase 4: Finalize** — Generate compliance report with PASS/BLOCKED/WARN verdicts
6. **Fix Loop: Validate → Fix → Full UI Re-Review** — validate findings first; fix only findings that block the current round, then rerun the full UI review using the local sub-agent selection guide only when that protocol calls for agents. Round 1 blocks on every validated severity; Round 2+ blocks only CRITICAL/HIGH/MEDIUM, LOW-only is recorded as deferred, and binary accessibility/security gates always block.
**Key Rules:**
- Write findings to `plans/reports/ui-review-{date}-{slug}.md`
- BLOCKED = must fix before merge | WARN = review and decide | PASS = compliant
- Every violation needs `file:line` proof + grep 3+ counterexamples before flagging
- Review is read-only until `$why-review --validate-findings` confirms findings; fixes may happen only in the validated fix loop or downstream plan/feature-implement, and every fix that blocks the current round restarts a full UI review from Phase 0 with brand-new tasks. From Round 2 onward, LOW-only findings end the loop and are recorded as deferred.
## Your Mission
<task>
$ARGUMENTS
</task>
## First Principle — Easy to Change
> **The success metric of every coding decision is _future change cost_.**
> DRY, SRP, abstraction, design patterns, naming, layering, tests — every
> technique exists to serve one goal: **making the next change cheaper**.
When evaluating styling, a layout, a token, or a component, ask:
**does this make the next change cheaper or more expensive?**
- Reject "best practices" that raise change cost (hardcoded values forcing
per-file edits, hand-rolled overflow handling, raw breakpoints,
copy-pasted truncation CSS).
- Name the real enemies in findings: **magic values, duplicated styling
knowledge, fixed sizing that fights the viewport, cross-system token
mixing, z-index escalation wars**.
- A simpler layout that survives 320px and a 200-char value beats a
pixel-perfect fixed layout that breaks on either.
Apply this lens **before** invoking any specific rule, pattern, or checklist
below — if a downstream rule would raise change cost, this principle wins.
---
## Review Mindset (NON-NEGOTIABLE)
Skeptical. Every claim needs traced proof, confidence >80%.
- NEVER flag a styling violation without reading the actual SCSS/template + tracing the rendered element
- Every finding MUST include `file:line` evidence
- Before flagging a pattern violation: grep 3+ existing examples — codebase convention wins
- Question: "Is this actually a violation, or an established exception (icon dimensions, fixed brand assets, genuinely fixed UI)?"
## Phase 0: Load UI Rules (MANDATORY FIRST) (MUST ATTENTION)
> **MUST ATTENTION:** Read project UI docs BEFORE reviewing. Rules come from docs, not general knowledge.
- read the project styling rules doc — extract BEM convention, mixin names, variable names, responsive breakpoint mixins, nesting limits
- read the project design-system/token doc — extract design tokens and the **Z-Index & Layering** section
- read the project frontend architecture/patterns doc — extract base component classes, store/effect patterns, API service base, lifecycle teardown pattern
- read the project code-review rules doc — extract frontend anti-patterns and review rules directly
> **CROSS-SYSTEM WARNING (carry through every category):** Do NOT mix token systems with incompatible root-size, namespace, or layer assumptions in one file. When flagging a fix, recommend whichever token system the file already imports/uses; never introduce another system unless the project docs explicitly require migration.
## Phase 1: Determine Scope
**Default (no override):** Review all uncommitted frontend changes.
```bash
git status # List changed files
git diff # Staged + unstaged changes
git diff --cached # Staged only
```
- Collect file list to review
- Filter to files matching the project frontend path/extension patterns resolved from project config/docs
- If ZERO frontend files match → announce `"No frontend changes detected — ui-review skipped"` and report clean (honor the CONDITIONAL skip)
## Phase 2: Blast Radius (if graph.db exists)
- If `.code-graph/graph.db` exists: run graph trace on key changed component files
- Record: impacted file count, shared-component fan-out (a changed shared-library component affects every consumer app), risk level
- Prioritize review by highest-impact files first (shared library components > app-local components)
- Graph unavailable: note "Graph not available — skipping blast radius" and proceed
For each changed component/style file with downstream impact:
```bash
python .claude/scripts/code_graph trace <changed-file> --direction both --json
```
Use `--node-mode file` first (10-30x less noise), then `--node-mode function` for detail. Flag shared-component consumers impacted by a styling or layout change.
## Phase 3: UI Category Review
Create report: `plans/reports/ui-review-{date}-{slug}.md`
For EACH file in scope, evaluate against ALL applicable categories. Skip categories not applicable to the file type (e.g., a pure `.ts` store file skips overflow/sizing/z-index but still hits Category 5's architecture checks and Category 6's loading/error/empty-state wiring).
> **Apply the `Think:` reasoning prompt before each category — derive violations, do NOT recite checklists.**
---
### Category 1: Long-Content Overflow & Truncation — Severity: WARN (HIGH when a flex child truncates with no `min-width: 0`)
**Think:** Does every text container survive a 200-char value? Single-line or multi-line? Can the user still read the full value when it is truncated?
**Detection signals:**
- Hand-rolled `text-overflow: ellipsis` (with `white-space: nowrap` / `overflow: hidden` re-declared by hand) instead of the project mixin/directive
- A flex child that truncates but has **NO `min-width: 0`** — the flex-overflow trap: a flex item's default `min-width: auto` refuses to shrink below content width, so ellipsis never triggers
- Truncated text with **NO tooltip / `title`** to reveal the full value
**DECISION RULE the reviewer enforces:**
- Single-line labels / table cells / chips → ellipsis **+ tooltip-on-overflow**
- Multi-line prose / descriptions → wrap or `-webkit-line-clamp`
**Project fix guidance** (cite real reuse targets from the resolved styling rules doc):
- Prefer the project's documented overflow/ellipsis directive, component, or utility. It must expose the full value only when the element actually overflows and must handle the flex `min-width` trap.
- OR the project's documented truncate/text-ellipsis mixins or utility classes from the styling rules doc.
- Multi-line: use the project-documented clamp pattern.
**GOOD vs BAD:** a utility/token-driven truncation that exposes the full value on overflow (tooltip/`title`) is correct; a hand-rolled substring / width-math truncation, or truncated text with no tooltip, is the anti-pattern. Cite the styling rules doc for the project's reuse targets.
---
### Category 2: Responsive Multi-Screen via Flex — Severity: WARN (BLOCKED only when content is broken on a small screen — clipped, cut off, or unreachable)
**Think:** Is this usable at 320 / 768 / 1024 / 1440? Does the layout flex, wrap, and **reflow from row to column** on small screens? If it genuinely cannot reflow, does it at least stay *usable* via a fixed `min-width`/`min-height` + `overflow: auto` scroll — or does content get clipped, cut off, or pushed out of reach?
**Small-screen usability — the minimum bar (canonical):**
- **Preferred:** reflow — `flex-wrap: wrap`, a `flex-direction: row → column` switch at the breakpoint, or a responsive grid that collapses to a single column.
- **Acceptable fallback:** when a layout genuinely can't reflow (dense tables, canvases, diagrams, wide data grids), a fixed `min-width`/`min-height` with `overflow: auto` is fine — **scrolling is OK, not a defect.** Do NOT flag a component BLOCKED merely because it scrolls.
- **Hard minimum (BLOCKED if violated):** on a small screen the UI is *usable* and nothing is **broken** — no clipped, cut-off, or unreachable content/controls (e.g. a submit button pushed off-screen with no scroll path, text overlapping, a fixed row that overflows AND hides content instead of scrolling).
- **Escalation:** if making a surface small-screen-usable would need a refactor too large for the current change, STOP and **confirm scope with the user** before proceeding — note it as a finding, do not silently rewrite the layout.
**Detection signals:**
- Raw `@media (max-width: NNNpx)` / `(min-width: NNNpx)` in component SCSS that bypasses the breakpoint mixins
- A multi-child flex `row` with **NO `flex-wrap`**, **NO `flex-direction: column`** override, AND **no `overflow: auto`** escape → content is trapped and clips on a phone (BLOCKED); the same row WITH a scroll escape is at most WARN (prefer reflow)
- Multi-column CSS grid with fixed column counts / fixed track widths and no single-column collapse and no scroll container at small breakpoints
- Non-flex fixed layouts (absolute positioning, fixed px widths on containers) that cannot reflow AND cannot scroll → content lost off-screen
- Content clipped, overlapping, or a control pushed out of reach below ~360px with no scroll path (BLOCKED). Horizontal scroll *by itself*, with all content still reachable, is the acceptable fallback — not a finding.
**Project fix guidance:**
- Preferred: the project documented responsive-flex mixins/utilities; add `flex-wrap: wrap` and/or the documented `row → column` breakpoint switch so the layout stacks vertically on small screens
- Fallback (when reflow isn't feasible): give the container a sensible `min-width`/`min-height` and `overflow: auto` so everything stays reachable by scroll
- Breakpoints from the project breakpoint tokens — NEVER inline pixel breakpoints
- Large layout refactor required → surface it as a finding and confirm with the user; don't bundle a big responsive rewrite into an unrelated change
**Anti-patterns:** raw `@media` pixel breakpoints that bypass the project's breakpoint mixins; a `flex-direction: row` with no wrap, no column fallback, AND no scroll escape so content clips; and non-flex fixed grids that neither reflow nor scroll. Cite the styling rules doc for documented offenders; grep the changeset for the same patterns.
---
### Category 3: Flex-Grow vs Fixed Width/Height (prefer min/max) — Severity: WARN
**Think:** Must this size be fixed, or can it grow/shrink with content + viewport?
**Detection signals:**
- Fixed `width:` / `height:` in px (≥ ~3 digits) on containers / cards / forms / dialogs
**Project fix guidance:**
- Prefer `flex: 1` / `flex-grow` + `max-width` / `min-width` caps, and `min-width: 0` on truncating flex children
- The project flex-container mixin/utility documented in the styling rules doc
- Reserve fixed px for icons / borders / genuinely fixed UI
**Anti-patterns:** large fixed `width:` / `height:` in px on containers / cards / forms / dialogs (e.g. `width: 964px`, `height: 772px`) that should flex with content + viewport. Cite the styling rules doc for documented offenders.
---
### Category 4: Z-Index Scale Discipline — Severity: BLOCKED (HARD GATE)
**Think:** Which layer does this surface belong to (base / raised / dropdown / sticky / modal / toast)?
**Detection signals:**
- Raw numeric `z-index` (literal value instead of a token)
- **ANY `z-index` with `!important` → BLOCKED** (an escalation war that the next dev will only beat with a bigger literal)
**Project fix guidance — use tokens:**
- The project documented z-index layer tokens
- Existing legacy/framework token systems only when the current file already uses that system
- The semantic layer variables declared canonical by the project design-system doc
Cross-reference the project design-system **Z-Index & Layering** map. The chosen token MUST match the surface's semantic layer.
**GOOD vs BAD:** a `z-index` set from a semantic token / layer scale is correct; a raw literal (e.g. `z-index: 99999`, `z-index: 10000`) or `z-index: N !important` is the anti-pattern. Cite the design-system and styling docs for the project's token scale and documented offenders.
---
### Category 5: SCSS/CSS Best Practices & BEM — Severity: WARN (BLOCKED on `!important`, chained BEM modifiers)
**Think:** Does this stylesheet read cleanly, follow BEM, and use tokens — or does it hardcode, over-nest, and chain modifiers?
> **SCSS/BEM rules (canonical):** BEM classes on ALL template elements (`block__element--modifier`). No magic numbers — use variables / design tokens. Max 3 nesting levels.
**Detection signals:**
- Nesting > 3 levels
- Hardcoded hex colors (should use CSS vars / design tokens)
- `px` where `rem` is expected
- Chained BEM modifiers (`.block__element.--modifier`) — `.--mod` MUST be a separate class, NEVER chained → BLOCKED
- Template elements missing BEM classes
- `!important` → BLOCKED
Apply fixes per the resolved project styling rules doc.
**Frontend architecture checks (OWNED JOINTLY WITH `architecture-review` Category 8 — reference, do not drift):**
> These checks are lifted from `architecture-review` Category 8 so the two skills stay synchronized. They are **owned jointly**; when one changes, update both. They apply to the `.ts` files in scope:
- Components MUST extend the project-documented base component/form/store component classes (BLOCKED)
- State MUST use the project-documented store/effect pattern — NEVER ad hoc local state when the project provides a canonical store pattern (BLOCKED)
- API services MUST extend the project-documented API service base — NEVER raw HTTP clients when the project provides a service abstraction (BLOCKED)
- All subscriptions MUST use the project's auto-teardown operator — NEVER manual unsubscribe (BLOCKED)
- All template elements MUST have BEM classes (WARN)
- Logic in lowest layer: Model > Service > Component (WARN)
---
### Category 6: Async UI States & Feedback — Loading / Error / Empty / Disabled — Severity: BLOCKED (HARD GATE when an async fetch or mutation renders NO loading indicator OR NO user-visible error surface)
> **This is the fundamental UI-resilience gate.** A screen whose happy path renders perfectly but shows a frozen blank while loading, fails silently on error, or shows nothing when empty is a broken user experience. Every async or interactive surface MUST answer three questions for the user: *what do I see while it's working, when it fails, and when there's nothing?*
**Think:** For EACH async operation the file performs (data fetch, form submit, mutation, navigation-triggered load, subscription), trace what the user actually sees in the in-flight, failure, and zero-result branches — not just the success branch. If any of those three branches renders a blank/frozen screen or nothing at all, that is the finding.
**The essential states every async/interactive surface MUST handle** (canonical vocabulary — shared verbatim with `design-spec` "Component States Checklist": Default / Loading / Disabled / Error / Empty / Success):
- **Loading** — every in-flight async request MUST render a loading indicator (spinner / skeleton / progress bar), NEVER a frozen or blank screen. Lists/tables → skeleton rows; buttons → in-button spinner + disabled.
- **Error** — every operation that can fail (network, validation, server error) MUST surface a human-readable error to the user WITH a recovery/retry path where sensible. NEVER a silent failure, a swallowed `catch`, or a raw stack trace / raw error object rendered to the user.
- **Empty** — every collection / list / table view MUST render a meaningful empty state (message + optional CTA) when it has zero items, NOT a blank area.
- **Disabled / in-flight guard** — submit/action controls MUST disable (or show busy) while their request is in-flight, to prevent double-submission.
- **Success** — a completed mutation SHOULD give confirmation feedback (toast / inline / visibly updated data).
**Detection signals:**
- An async call (fetch / HTTP / `subscribe` / awaited mutation) whose template binds NO loading flag (`isLoading` / `pending` / `loading$` / skeleton) → **BLOCKED**
- A `.catch` / `try-catch` / error callback that logs or swallows the error but renders NO user-visible error surface → **BLOCKED**
- A raw error shown to the user (stack trace, raw JSON, unmapped exception) → WARN
- A list/table rendered from a collection with NO empty-state branch (`@empty`, `*ngIf="!items.length"`, `items.length === 0 ? …`) → WARN (BLOCKED when the collection is the screen's primary content)
- A submit handler that does NOT disable its trigger while in-flight (double-submit risk) → WARN (BLOCKED for payment / create / irreversible actions)
> **Check for centralized handling BEFORE flagging BLOCKED (avoid false positives):** many apps satisfy loading/error at the app level — a route-level progress bar, an HTTP interceptor that shows a global spinner/toast, an error boundary, or a base component that renders loading/error for all its children. If such a mechanism demonstrably covers this surface, the local component is compliant — grep for the shared mechanism (per this skill's "grep 3+ counterexamples / established exception" rule) and downgrade or drop the finding. Flag BLOCKED only when NO layer — local or global — gives the user a loading indicator / error surface.
**Project fix guidance** (cite real reuse targets from the resolved frontend/patterns + design-system docs):
- Prefer the project's documented loading component / skeleton / spinner and the documented error-banner / empty-state components or patterns — NEVER hand-roll one-off state UI when a canonical one exists.
- Bind loading / error / empty off the store / view-model / API-service state per the project's documented state pattern — state belongs in the lowest layer (Model > Service > Component), not improvised in the template.
**GOOD vs BAD:** a fetch bound to `isLoading` → skeleton, `error` → inline retry banner, and empty → placeholder is correct; a fetch that renders ONLY the populated happy path (blank while loading, nothing on error, blank when empty) is the anti-pattern. Cite the frontend-patterns and design-system docs for the project's reuse targets.
> **Note vs Category 5's Bug-Detection "Error Handling":** the shared Bug Detection protocol checks that `catch` scope is correct and exceptions are not swallowed at the *code* level; Category 6 checks that the failure/loading/empty branch produces a *user-visible* state at the *UI* level. Both must pass — a correctly-caught error that renders nothing still fails Category 6.
---
## Phase 3B: UI/UX Design Principles Pass (9 dimensions)
The 40 clauses of `SYNC:ui-ux-design-principles` (full body inlined below in this skill) bind this skill in the **REVIEW** role: every clause is a fail-condition, not a suggestion. Run them as **NINE focused passes over the whole scope — one dimension at a time, in order.** A single simultaneous sweep of all nine is what degrades clause review into tick-boxing; serial attention is the mechanism, not a formatting preference.
**Per pass:** answer the `Think:` prompt from first principles FIRST — *what would make this dimension fail on THIS surface?* — then hunt the violation that reasoning predicts. A pass that produced no reasoning produced no review: record the reasoning, never a tick.
**Every finding:** `UI-<clause>` + `file:line` + severity from the Phase 4 rubric already in force (**BLOCKED** must fix before merge · **WARN** review and decide · **PASS** compliant; a WARN escalates to BLOCKED under the escalation rule stated there). This pass introduces NO new severity scale.
**Precedence (MUST ATTENTION):** the project styling / design-system / frontend-pattern docs loaded in Phase 0 **OUTRANK** these clauses; the clauses outrank generic taste. Where a project doc states its own value (type scale, spacing unit, breakpoints, token contrast pairs), the PROJECT value is the rule and the clause is satisfied by following it. A genuine conflict is SURFACED to the user by asking the user directly with both sides — NEVER resolved silently.
| # | Dimension | Clauses | `Think:` |
| --- | ------------------------- | ------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| 1 | Visual Hierarchy & Layout | `UI-1.1`-`UI-1.5` | Which element does a first-time user's eye land on, and is it the one this screen exists for? Which groups are held together by whitespace, and which by a border added because the whitespace was wrong? Are the empty, loading and error states designed at all — or only the full state? |
| 2 | Typography | `UI-2.1`-`UI-2.5` | Trace every family/size/weight declaration in scope back to the project type scale — which are one-off literals? At the widest breakpoint, how many characters per line does body text actually reach, and does any text a user must read fall below 14px? |
| 3 | Colour & Contrast | `UI-3.1`-`UI-3.4` | For each foreground/background pair that actually renders, what is the COMPUTED ratio (measured — never judged by eye)? What does a user who cannot perceive the accent hue see instead? In dark mode, is elevation signalled by lifted surfaces or by an inversion? |
| 4 | Spacing & Grid | `UI-4.1`-`UI-4.4` | Is every gap a multiple of the project base unit, or are there arbitrary values? Does spacing come from the container (`gap`) or from margins scattered across children? Is inner padding smaller than the gap to the next group? Do breakpoints break where the layout fails, or where a device is named? |
| 5 | Interaction & Feedback | `UI-5.1`-`UI-5.5` | For each interactive element: what changes visually within 100ms of the press? Which of the five states (default/hover/focus/active/disabled) is unstyled? Is the focus ring still visible after restyling? Could undo replace this confirmation? Does motion honour reduced-motion? |
| 6 | Navigation & IA | `UI-6.1`-`UI-6.4` | Landing on this screen cold: where am I, what's here, where next? How many top-level destinations exist? Are labels the user's words or the team's internal vocabulary? Does this state have a URL or back path, and where does hardware back land? |
| 7 | Forms & Input | `UI-7.1`-`UI-7.5` | Field by field: what breaks if this field is removed today? Is its label still visible once filled? When does validation fire, and does the message say how to fix it? Does the keyboard/autocomplete match the data type? What happens to typed data on validation error, navigation away, and refresh? |
| 8 | Mobile & Touch | `UI-8.1`-`UI-8.4` | At a touch viewport: measure each tappable element's HIT BOX (not the icon) and the gap to its neighbours; where do primary actions sit relative to the thumb; is anything reachable ONLY by gesture; what do notch, home indicator and the on-screen keyboard cover? _(Mobile/touch surfaces only — when the scope has none, say so explicitly.)_ |
| 9 | Speed & Perceived Speed | `UI-9.1`-`UI-9.4` | For everything that loads: what occupies its space before data arrives, and does the layout shift when it lands? Is the optimistic path rolled back VISIBLY on failure? On a slow or offline connection, what does the user see — a designed state or a hang? |
**No double-counting.** Several clauses overlap Categories 1-6 (`UI-1.5`/`UI-5.2`/`UI-9.1` overlap Category 6's async-state gate; `UI-2.3` overlaps Category 1's content handling; `UI-4.1` overlaps Category 5's magic-number rule; `UI-4.4` overlaps Category 2's responsive bar). Where they meet, emit **ONE** finding carrying BOTH citations (e.g. `Category 6` + `UI-5.2`) at the HIGHER of the two severities — never two findings for one defect, and never a downgrade because "the other category already covers it".
**Skip rule.** This pass runs whenever any frontend file is in scope. Skip an individual dimension ONLY when the scope contains no surface it can apply to (`UI-8.*` with no touch surface, `UI-7.*` with no input) — name the skipped dimensions and the reason, so a skip is auditable rather than an omission.

## Phase 3C: Design Distinctiveness Pass (`DD-1`–`DD-8`)
Phase 3B asked **"is this usable, accessible, and consistent?"** — a floor with measurable pass/fail. This pass asks the question none of the 40 clauses ask: **"is this THIS product's interface, or the one any generator would emit for any brief?"** A surface can pass every clause in Phase 3B and still be a template. The 8 clauses of `SYNC:design-distinctiveness-gate` (full body inlined below in this skill) bind this skill in the **REVIEW** role; the deep catalog is `.claude/docs/design-knowledge.md`.
**Run as FOUR focused passes, one at a time, in order** — same serial-attention mechanism as Phase 3B:
| # | Pass | Clauses | `Think:` |
| --- | --- | --- | --- |
| 1 | Identity & rationale | `DD-1`, `DD-2` | If I swapped this product for a different one in the same shape, which of these choices would have to change? The ones that would not are where the design defaulted. Read the token/variable names alone — could a reader guess what product this is, or do they read `--gray-700`/`--surface-2`? |
| 2 | Free-axis tell audit | `DD-4` | Which axes did the brief, the project design system, or an accepted ADR actually PIN — and which were free? On each FREE axis, does the code land on a T1–T5 cluster (cream+serif+`#D97757` · acid-on-black · broadsheet · the SaaS-card kit: identical cards, one radius for every hierarchy level, the same `rgba(0,0,0,.1)` shadow, gradient washes as decoration · template chrome: ALL-CAPS eyebrows, `A · B · C` middle-dot meta, spaced-em-dash labels, `#0B0B0B` for black, mono data labels, trailing `→`)? |
| 3 | Type, structure & motion | `DD-5`, `DD-6`, `DD-7` | How many families and how distinct? Does body text exceed ~80ch? Is a single word in a headline accented, are labels ALL CAPS, does an eyebrow just restate its heading? Do numbered markers sit on content that is genuinely a sequence? What does each border tell the reader that whitespace would not? Is there ONE orchestrated motion moment, or a fade-and-slide-up on every section plus a hover transition on every card? |
| 4 | Restraint & CSS honesty | `DD-8` | Where is the boldness spent — once, or scattered? Which decoration would the page not miss? Find the CSS lies: negative margins undoing a parent's padding, `calc()` values that exist only as workarounds, absolute positioning to escape layout flow, and type-vs-element selectors (`.section` vs `.cta`) cancelling each other's padding/margin. |
**Every finding:** `DD-<clause>` + `file:line` + a severity from the Phase 4 rubric already in force. This pass introduces NO new severity scale.
**Severity ceiling (MUST ATTENTION).** A `DD-4` tell match is a **hypothesis about a missed decision, never a defect** — it caps at **WARN**, and the finding is INVALID unless it names (a) the axis, (b) the evidence that the brief/project left that axis free, and (c) what the subject matter suggested instead. `DD-5`/`DD-6`/`DD-7` findings that are also `UI-*` violations (a sub-14px label, an unmeasured contrast pair, motion ignoring reduced-motion) take the `UI-*` severity. Only `DD-8`'s CSS-honesty findings reach **BLOCKED** on their own, and only where the hack actually breaks layout or maintainability.
**Precedence (MUST ATTENTION), strictest in this skill:** the **brief's stated visual direction WINS OUTRIGHT** — a design that was asked for one of the T1–T5 looks and delivered it is a PASS, not a finding. Then the project design-system / SCSS / frontend-pattern docs loaded in Phase 0 — **an established house style is an intentional identity, and a repo-wide convention is NEVER a `DD-4` finding.** NEVER open a finding that amounts to "this looks like other software" without the three-part evidence above. — why: an unevidenced distinctiveness finding is pure taste asserted as a defect, and it pushes a codebase toward a *different* uniform at review cost.
**No double-counting.** Where a `DD-*` clause meets a Category 1–6 check or a `UI-*` clause, emit **ONE** finding carrying BOTH citations at the HIGHER severity — never two findings for one defect.
**Skip rule.** Runs whenever the scope renders a user-facing visual surface. Skip entirely for pure logic/store/service changes with no rendered output — state that reason explicitly so the skip is auditable.
---
## Phase 4: Finalize — UI Compliance Report
Update report with final sections:
### Verdict Scoring
| Overall verdict | Condition |
| --------------- | --------- |
| **FAIL** | Any failed binary gate or unresolved evidence; any validated finding in round 1; any validated CRITICAL/HIGH/MEDIUM in round 2+; or persisted `minRounds` not yet met. |
| **PASS** | All binary gates and evidence resolved, current-round blocking findings empty, and persisted `minRounds` met. Record round-2+ LOW findings as deferred; they do not force another cycle. |
> **Severity vocabulary (single source of truth).** Category headers may use `BLOCKED` / `WARN`; the overall verdict is `PASS / FAIL` under `review-policy.cjs`, never the category label alone. The fresh sub-agent emits `Critical / High / Medium / Low`. Assign consequence first using the canonical rubric, then apply the round predicate:
>
> | Category label | Canonical finding | Round handling |
> | -------------- | ----------------- | -------------- |
> | BLOCKED | CRITICAL / HIGH | Blocks every round. |
> | WARN | MEDIUM when bounded but consequential | Blocks every round. |
> | WARN | LOW when non-blocking polish | Blocks round 1; record/defer in round 2+. |
> | No finding | Evidence-backed compliant or N/A | No severity finding; binary gates and the persisted minimum still apply. |
>
> A category's **"(HIGH when …)"** note is NOT a separate tier — it means that WARN **escalates to BLOCKED** when the stated condition holds (i.e., the finding is a real rendered bug, not a latent risk).

## Systematic Review Protocol (10+ changed frontend files)
1. **Categorize** — Group files by app / shared-library / component concern
2. **Parallel Sub-Agents** — Launch one UI/UX-specialized sub-agent per group with the UI-category checklist
3. **Synchronize** — Collect findings, cross-reference shared-component consumers and cross-system token mixing
4. **Consolidate** — Single holistic report with per-category verdicts
---
## Phase 5: Why-Review Findings Validation Gate (MANDATORY when findings exist)
> **Purpose:** Adversarial validation of own findings BEFORE handoff. Catches over-flagged Highs, false positives, and severity inflation at the source rather than letting them propagate downstream.
**Trigger:** Any finding produced (Critical, High, Medium, OR Low). Skip ONLY when the report's verdict is unconditional PASS with literally zero findings.
**Protocol:**
1. Read own finalized report from `plans/reports/ui-review-{date}-{slug}.md` (the exact path written in Phase 3 — NOT `{skill}-…`)
2. Invoke `$why-review --validate-findings plans/reports/ui-review-{date}-{slug}.md`
3. Read the validation verdict path returned by why-review, expected as `plans/reports/why-review-validate-{date}.md`
4. **If why-review demotes/removes any finding:** UPDATE own finalized report with revised severities, remove false positives, and add a `## Why-Review Validation Notes` section citing what changed and why
5. **If why-review confirms all findings:** Append `## Why-Review Validation` line to own report stating "All N findings re-validated against actual code; no severity changes."
6. **If the report changed after validation:** re-run this validation gate, maximum 2 validation passes, until the report's remaining findings are validated or zero findings remain.
**Skip conditions (record explicit reason if skipping):**
- Verdict is unconditional PASS with zero findings → log "Skipped — no findings to validate"
- Why-review skill itself is the active context (avoid recursion)
**Why this exists:** AI sub-agent reports inherit confirmation bias — the orchestrator absorbs severity claims as ground truth. The 2026-05-09 review incident produced 5 Highs; adversarial validation demoted 3 of them. Codify this as standard practice.
---
## Phase 6: Validated Fix + Full UI Re-Review Loop (MANDATORY when validated findings remain)
**Trigger:** Phase 5 returns CLEAN/validated and the UI review report still has one or more findings that must be fixed.
**Protocol:**
1. Create a fresh fix-cycle task list before editing. Do not reuse the review tasks.
2. Fix only findings that survived `$why-review --validate-findings`; route broader or cross-cutting fixes through the parent `$plan` + `$feature-implement` flow when this skill is running inside a workflow.
3. Run targeted verification for the fixed UI files and any affected consumers.
4. Re-invoke `$ui-review` from Phase 0 over the full current UI scope, not only the fixed files.
5. The re-run MUST create brand-new review tasks, reload the UI docs, determine scope again, rerun blast radius where applicable, and review every changed UI file from the start.
6. Repeat validate → fix → full UI re-review until a complete pass clears the current round's exit bar (round 1: zero findings; round 2+: zero CRITICAL/HIGH/MEDIUM, LOW deferred).
7. If the same validated blocker repeats across 2 full invocations with no progress, stop and ask the user for a decision.
**Non-negotiable rules:**
- Never fix a finding before `$why-review --validate-findings` validates it.
- Never mark UI review clean after a targeted fix check only; the clean verdict must come from a full Phase 0 restart.
- Never review only fixed files during the recursive pass; analyze all UI files in scope again.
- Never reuse old todo/task items for the recursive review pass.
---
## Workflow Recommendation
> **MANDATORY — NO EXCEPTIONS:** If NOT already in a workflow, MUST use ask the user directly to ask user. Do NOT judge task complexity or decide "simple enough to skip" — user decides, not you:
>
> 1. **Activate `workflow-review-changes` workflow** (Recommended) — run the canonical workflow from `.claude/workflows.json`; it runs UI review in TWO places by design (keep both) — internally as `$changes-review`'s UI dimension AND as a dedicated conditional parallel-batch reviewer (step 9) — alongside findings validation, the other parallel reviewers, `code-simplifier` self-review, fix-plan cycle, full re-review restart, docs, and handoff.
> 2. **Execute `$ui-review` directly** — run this skill standalone
---
## Next Steps
**MANDATORY — NO EXCEPTIONS:** After completing, use ask the user directly to present:
- **"$code-simplifier" (Recommended)** — Simplify and refine the styling/component code
- **"$web-design-guidelines"** — Generic accessibility / UX checklist for a11y depth
- **"Skip, continue manually"** — user decides
## AI Agent Integrity Gate (NON-NEGOTIABLE)
Before reporting ANY work done:
1. **Grep every removed name.** Extraction/rename/delete → grep confirms 0 dangling refs across ALL file types (SCSS `@use`, template class refs, TS imports)
2. **Ask WHY before changing.** Existing values intentional until proven otherwise — a fixed `width` may be a genuinely fixed UI element; no "fix" without traced rationale
3. **Verify ALL outputs.** One compiled stylesheet ≠ all consumers — a shared-component style change affects every consuming app
4. **Evaluate pattern fit.** Copying a nearby mixin/token? Verify the file imports/uses the SAME token system and does not mix incompatible project token systems
5. **New artifact = wired artifact.** Created a class/mixin? Prove it is imported, referenced in the template, and reachable
> **[IMPORTANT]** Use task tracking to break ALL work into small tasks BEFORE starting. Simple tasks: ask user whether to skip.
<!-- OVERRIDE:fresh-context-review -->
> **Fresh Context Re-Review** — Eliminate orchestrator confirmation bias after fixes by restarting the full review with isolated sub-agents where applicable.
>
> **Why:** The main agent knows what it (or `$feature-implement`) just fixed and rationalizes findings accordingly. A fresh sub-agent has ZERO memory, re-reads from scratch, and catches what the main agent dismissed. Sub-agent bias is mitigated by (1) fresh context, (2) verbatim protocol injection, (3) main agent not filtering the report.
>
> **When:** ONLY after a validated-finding fix cycle, or when the user/workflow explicitly requests an independent high-risk UI synthesis pass. A review pass that finds issues triggers validation first; it does NOT trigger a fresh-context pass over the same findings before validation/fix.
>
> **How:**
>
> 1. Start a NEW full review invocation/task breakdown; when that protocol calls for agents, spawn a NEW `spawn_agent` tool call — use the UI/UX-specialized agent_type from the local sub-agent selection guide
> 2. Inject ALL required review protocols VERBATIM into the prompt — see `SYNC:review-protocol-injection` for the full list and template. Never reference protocols by file path; AI compliance drops behind file-read indirection (see `SYNC:shared-protocol-duplication-policy`)
> 3. Sub-agent re-reads ALL target files from scratch via its own tool calls — never pass file contents inline in the prompt
> 4. Sub-agent writes structured report to `plans/reports/{review-type}-round{N}-{date}.md`
> 5. Main agent reads the report, integrates findings into its own report, DOES NOT override or filter
>
> **Rules:**
>
> - NEVER reuse a sub-agent across rounds — every iteration that uses sub-agents spawns a NEW `spawn_agent` call
> - NEVER fix unvalidated findings; validate first using the caller's validation gate
> - NEVER skip the full review restart after a validated fix cycle — every fix invalidates the prior verdict
> - Continue until a complete full review pass clears the current round's exit bar and persisted `minRounds` (round 1: zero findings; round 2+: zero CRITICAL/HIGH/MEDIUM, LOW deferred); if the same blocker repeats across 2 full invocations with no progress, escalate by asking the user directly
> - Persist completed rounds, repeated blockers, findings and the explicit minimum in the owning run's `review-policy.cjs` record. Resume that record after interruption; target changes invalidate evidence and acceptance but preserve the bounded round budget. In-flight attempt IDs may be session-local; they do not replace or reset completed-round state
<!-- /OVERRIDE:fresh-context-review -->
## Sub-Agent Type Override
> **MANDATORY:** UI reviews spawn the UI/UX-specialized sub-agent defined by the local sub-agent selection guide.
> Keep `agent_type: "ui-ux-designer"` in the canonical template below when that agent type exists in the local catalog.
> **Rationale:** The shared sub-agent selection guide routes frontend UI/UX, accessibility, responsive layout, and design-token work to the UI/UX specialization. Do not fall back to a generic code-reviewer catch-all unless the local catalog lacks a UI/UX reviewer.
<!-- OVERRIDE:review-protocol-injection -->
> **Review Protocol Injection** — Every fresh sub-agent review prompt MUST embed 11 protocol blocks VERBATIM. The template below has ALL 11 bodies already expanded inline. Copy the template wholesale into the Agent call's `prompt` field at runtime, replacing only the `{placeholders}` in Task / Round / Reference Docs / Target Files / Output sections with context-specific values. Do NOT touch the embedded protocol sections.
>
> **Why inline expansion:** Placeholder markers would force file-read indirection at runtime. AI compliance drops significantly behind indirection (see `SYNC:shared-protocol-duplication-policy`). Therefore the template carries all 11 protocol bodies pre-embedded.
### Subagent Type Selection
- `ui-ux-designer` — default for UI reviews when the local agent catalog provides it
- `code-reviewer` — fallback only when the local catalog lacks a UI/UX-specialized reviewer
### Canonical Agent Call Template (Copy Verbatim)
```
spawn_agent({
description: "Fresh Round {N} UI review",
agent_type: "ui-ux-designer",
prompt: `
## Task
{review-specific task — e.g., "Review all uncommitted frontend changes for UI quality: long-content overflow, responsive layout (flex-wrap / row→column, usable on small devices), flex-vs-fixed sizing, z-index discipline, SCSS/BEM, and async UI states & feedback (loading indicator, user-visible error surface, empty state, in-flight disable)" | "Review SCSS/template files under {path}"}
## Round
Round {N}. You have ZERO memory of prior rounds. Re-read all target files from scratch via your own tool calls. Do NOT trust anything from the main agent beyond this prompt.
## Protocols (follow VERBATIM — these are non-negotiable)
### Spec ↔ Tests ↔ Code Triangulation
DO THIS FIRST — before any per-protocol check below. The review target is the WHOLE PACKAGE, not the diff alone: load the behavior's spec (§3 ACs / §4 BRs / §8 TCs), its tests, and the changed code TOGETHER, and reason about their mutual consistency BEFORE judging any one in isolation.
1. Locate all three faces: the Feature Spec section(s) governing the changed behavior, the tests that guard it, and the production code that implements it. A missing face is itself a finding (SPEC-GAP / TEST-GAP / DEAD-SPEC).
2. Triangulate pairwise — every disagreement is a finding; classify which face is wrong:
- code vs spec: behavior the code does that no §3/§4/§8 rule describes → CODE-EXTRA or SPEC-STALE; a [HARD] §4 rule or §5 invariant with no enforcing code path → CODE-WRONG.
- tests vs spec: a §8 TC with no test, or a test asserting behavior no TC/rule names → TEST-GAP or SPEC-SILENT.
- tests vs code: a changed code path with no covering test → TEST-GAP; a test that still passes against a deliberately broken invariant → WEAK-TEST (apply the mutation thinking in Bug Detection).
3. Hidden-rule capture: any invariant the code enforces but the spec never states (SPEC-SILENT) MUST be surfaced as a finding to add into §3/§4/§8 AND guarded with a test — the enrichment loop, never a silent pass.
4. Only after the three faces agree — or every disagreement is logged as a finding — proceed to the per-protocol checks below; when enrichment adds spec/test content, re-review the package against the enriched spec.
NEVER mark review PASS while any spec/test/code face disagrees without a logged finding. The diff is the entry point; the package is the unit of judgment.
### Evidence-Based Reasoning
Speculation is FORBIDDEN. Every claim needs proof.
1. Cite file:line, grep results, or framework docs for EVERY claim
2. Declare confidence: >80% act freely, 60-80% verify first, <60% DO NOT recommend
3. Cross-service validation required for architectural changes
4. "I don't have enough evidence" is valid and expected output
BLOCKED until: Evidence file path (file:line) provided; Grep search performed; 3+ similar patterns found; Confidence level stated.
Forbidden without proof: "obviously", "I think", "should be", "probably", "this is because".
If incomplete → output: "Insufficient evidence. Verified: [...]. Not verified: [...]."
### Bug Detection
MUST check categories 1-4 for EVERY review. Never skip.
1. Null Safety: Can params/returns be null? Are they guarded? Optional chaining gaps? .find() returns checked?
2. Boundary Conditions: Off-by-one (< vs <=)? Empty collections handled? Zero/negative values? Max limits?
3. Error Handling: Try-catch scope correct? Silent swallowed exceptions? Error types specific? Cleanup in finally?
4. Resource Management: Connections/streams closed? Subscriptions unsubscribed on destroy? Timers cleared? Memory bounded?
5. Concurrency (if async): Missing await? Race conditions on shared state? Stale closures? Retry storms?
6. Stack-Specific: Check the configured language/runtime pitfalls and framework-specific failure modes discovered from local code.
Classify every finding by consequence using `SYNC:severity-rubric` (never by effort): CRITICAL = immediate material security/safety/data-loss risk or failed binary gate → block; HIGH = material correctness, contract, privacy, or authority risk → must fix; MEDIUM = bounded consequential edge/resilience/maintainability gap → must clear the current round, or escalate with an explicit residual-risk follow-up that does not create a clean pass; LOW = non-blocking polish with no credible present impact → record/defer from round 2; `NOT VERIFIABLE` is unresolved evidence, not LOW.
### Design Patterns Quality
Priority checks for every code change:
1. DRY via OOP: Same-suffix classes (*Entity, *Dto, *Service) MUST share base class. 3+ similar patterns → extract to shared abstraction.
2. Right Responsibility: Logic in LOWEST layer (Entity > Domain Service > Application Service > Controller). Never business logic in controllers.
3. SOLID: Single responsibility (one reason to change). Open-closed (extend, don't modify). Liskov (subtypes substitutable). Interface segregation (small interfaces). Dependency inversion (depend on abstractions).
4. After extraction/move/rename: Grep ENTIRE scope for dangling references. Zero tolerance.
5. YAGNI gate: Recommend extraction when 3+ similar patterns exist OR an evidenced consumer boundary/substitution need justifies it; do not create patterns for hypothetical future use.
6. Purpose-oriented naming: Name public or cross-layer abstractions by the capability, domain purpose, or contract consumers rely on—not the current provider, SDK, framework, database, or transport. `IStorage`/`Storage` → `AzureBlobStorage`; use `IAzureStorage` only when Azure-specific semantics are intentionally part of the contract.
7. Contract-fit check: Read callers and every implementation before judging a name; narrow an over-broad abstraction (`IObjectStore`, `DocumentStore`) instead of rewarding a generic name that lies about behavior.
8. Mechanism/generic-name smell: Treat `Manager`, `Helper`, `Utils`, `Data`, `Thing`, `Service`, `Interface`, type decorations, and unexplained abbreviations as review signals—not automatic defects; flag them only when they hide purpose, scope, or responsibility.
9. Concrete implementation names: Provider, strategy, transport, or test-double names are valid on concrete types when they distinguish real behavior (`AzureBlobStorage`, `InMemoryStorage`, `RetryingStorage`); keep those details out of the caller-facing contract unless the contract promises them.
10. Language convention: Preserve local interface syntax and naming style; `.NET` `I` prefixes and Google TypeScript's unmarked interfaces are both valid local conventions.
Anti-patterns to flag: God Object, Copy-Paste inheritance, Circular Dependency, Leaky Abstraction.
### Logic & Intention Review
Verify WHAT code does matches WHY it was changed.
1. Change Intention Check: Every changed file MUST serve the stated purpose. Flag unrelated changes as scope creep.
2. Happy Path Trace: Walk through one complete success scenario through changed code.
3. Error Path Trace: Walk through one failure/edge case scenario through changed code.
4. Acceptance Mapping: If plan context available, map every acceptance criterion to a code change.
5. Tests Verify Intent: For test/spec changes, verify tests name the protected business rule or invariant and would fail if that intent breaks.
6. Migration Test Exclusion: Do not write tests for migration code. Schema/data migrations are one-time execution paths, not core application logic.
NEVER mark review PASS without completing both traces (happy + error path).
### Test Spec Verification
Map changed code to test specifications.
1. Identify the project's test/spec format from existing docs, test-case files, BDD feature files, or spec folders.
2. Every changed code path MUST map to a corresponding test case/spec (or flag as "needs test case").
3. New functions/endpoints/handlers → flag for test spec creation.
4. Migration files are excluded from test/spec creation; schema/data migrations are one-time execution paths, not core application logic.
5. If spec evidence fields exist, verify they point to actual code (file:line, not stale references).
6. Verify each meaningful test case names the business intent/invariant; flag behavior-only cases that only mirror implementation details.
7. Auth/data changes → verify corresponding authorization and data-state test cases exist.
8. If no specs exist for a changed path → log the gap and recommend the project's test-spec workflow.
NEVER skip test mapping. Untested code paths are the #1 source of production bugs.
### Behavioral Delta Matrix
MANDATORY for any bugfix review. Produce input-state × pre-fix × post-fix × delta table BEFORE writing verdict.
- Minimum 3 rows; include at least one row OUTSIDE the original bug report.
- Any "REGRESSION" delta → review returns FAIL until a preservation test is added.
- Narrative descriptions do NOT substitute for the matrix.
Example rows (external-record sync fix):
| Input | Pre-fix | Post-fix | Delta |
| --------------------- | ------- | ------------------------- | ---------- |
| Record exists (valid) | Reused | Always recreated → orphan | REGRESSION |
| Record missing (404) | Error | Recreated | Fixed |
### Fix-Layer Accountability
NEVER fix at the crash site. Trace the full flow, fix at the owning layer. The crash site is a SYMPTOM, not the cause.
MANDATORY before ANY fix:
1. Trace full data flow — Map the complete path from data origin to crash site across ALL layers (storage → backend → API → frontend → UI). Identify where bad state ENTERS, not where it CRASHES.
2. Identify the invariant owner — Which layer's contract guarantees this value is valid? Fix at the LOWEST layer that owns the invariant, not the highest layer that consumes it.
3. One fix, maximum protection — If fix requires touching 3+ files with defensive checks, you are at the wrong layer — go lower.
4. Verify no bypass paths — Confirm all data flows through the fix point. Check for direct construction skipping factories, clone/spread without re-validation, raw data not wrapped in domain models, mutations outside the model layer.
BLOCKED until: Full data flow traced (origin → crash); Invariant owner identified with file:line evidence; All access sites audited (grep count); Fix layer justified (lowest layer that protects most consumers).
Anti-patterns (REJECT): "Fix it where it crashes" (crash site ≠ cause site, trace upstream); "Add defensive checks at every consumer" (scattered defense = wrong layer); "Both fix is safer" (pick ONE authoritative layer).
### Rationalization Prevention
AI skips steps via these evasions. Recognize and reject:
- "Too simple for a plan" → Simple + wrong assumptions = wasted time. Plan anyway.
- "I'll test after" → RED before GREEN. Write/verify test first.
- "Already searched" → Show grep evidence with file:line. No proof = no search.
- "Just do it" → Still need task tracking. Skip depth, never skip tracking.
- "Just a small fix" → Small fix in wrong location cascades. Verify file:line first.
- "Code is self-explanatory" → Future readers need evidence trail. Document anyway.
- "Combine steps to save time" → Combined steps dilute focus. Each step has distinct purpose.
### Graph-Assisted Investigation
MANDATORY when .code-graph/graph.db exists.
HARD-GATE: MUST run at least ONE graph command on key files before concluding any investigation.
Pattern: Grep finds files → trace --direction both reveals full system flow → Grep verifies details.
- Investigation: trace --direction both on 2-3 entry files
- Fix/Debug: callers_of on buggy function + tests_for
- Feature/Enhancement: connections on files to be modified
- Code Review: tests_for on changed functions
- Blast Radius: trace --direction downstream
CLI: python .claude/scripts/code_graph {command} --json. Use --node-mode file first (10-30x less noise), then --node-mode function for detail.
### Understand Code First
HARD-GATE: Do NOT write, plan, or fix until you READ existing code.
1. Search 3+ similar patterns (grep/glob) — cite file:line evidence.
2. Read existing files in target area — understand structure, base classes, conventions.
3. Run python .claude/scripts/code_graph trace <file> --direction both --json when .code-graph/graph.db exists.
4. Map dependencies via connections or callers_of — know what depends on your target.
5. Write investigation to .ai/workspace/analysis/ for non-trivial tasks (3+ files).
6. Re-read analysis file before implementing — never work from memory alone.
7. NEVER invent new patterns when existing ones work — match exactly or document deviation.
BLOCKED until: Read target files; Grep 3+ patterns; Graph trace (if graph.db exists); Assumptions verified with evidence.
## Reference Docs (READ before reviewing)
- {resolved project styling rules doc}
- {resolved project design-system/token doc, especially Z-Index & Layering}
- {resolved project frontend architecture/patterns doc}
- {resolved project code-review rules doc}
## Target Files
{explicit file list OR "run git diff and filter by the project frontend path/extension patterns"}
## Output
Write a structured report to plans/reports/ui-review-round{N}-{date}.md with sections:
- Status: PASS | FAIL
- Issue Count: {number}
- Critical Issues (with file:line evidence)
- High Priority Issues (with file:line evidence)
- Medium / Low Issues
- Cross-cutting findings (cross-system token mixing, shared-component fan-out)
Return the report path and status to the main agent.
Every finding MUST have file:line evidence. Speculation is forbidden.
`
})
```
### Rules
- DO copy the template wholesale — including all 11 embedded protocol sections
- DO replace only the `{placeholders}` in Task / Round / Reference Docs / Target Files / Output sections with context-specific content
- DO keep the UI/UX-specialized `agent_type` for UI reviews when the local catalog provides it (see Sub-Agent Type Override above)
- DO NOT paraphrase, summarize, or skip any protocol section
- DO NOT pass file contents inline — the sub-agent reads via its own tool calls so it has a fresh context
- DO NOT reference protocols by file path or tag name — the bodies are already embedded above
- DO NOT introduce placeholder markers for the protocols — they must stay literally expanded
<!-- /OVERRIDE:review-protocol-injection -->
> **Critical Purpose:** UI quality — no content overflow without escape, no broken responsive layouts (rows that never wrap or stack on small devices), no fixed sizing fighting the viewport, no z-index escalation wars, no styling/BEM drift, and no async surface that leaves the user staring at a frozen blank while loading, a silent failure on error, or a blank area when empty.
> **External Memory:** Complex/lengthy work → write findings to `plans/reports/`. Prevents context loss, serves as deliverable.

> **`fresh-context-review` is intentionally OVERRIDE-only in this skill** — see the `OVERRIDE:fresh-context-review` block above (it uses the UI/UX-specialized `ui-ux-designer` agent_type, NOT the generic `code-reviewer`). The generic `SYNC:fresh-context-review` copy is deliberately omitted here so the two cannot drift into a `code-reviewer` vs `ui-ux-designer` contradiction. This mirrors how `OVERRIDE:review-protocol-injection` is handled (override-only, no generic SYNC copy). **Do NOT re-add the generic `SYNC:fresh-context-review` block** — the `sync-inline-versions.md` propagation only updates existing `SYNC:` markers, so omission is stable.
> **`ui-ux-design-principles` is deliberately NOT inside the `OVERRIDE:review-protocol-injection` template.** That template's protocol region MUST stay substance-identical to canonical `SYNC:review-protocol-injection` across all three OVERRIDE carriers (`integration-test-review`, `architecture-review`, `ui-review`) — `sync-carrier-parity.test.cjs` pins it, precisely because those copies silently drifted once before. Adding a 12th protocol here fails that guard. The dispatched reviewer still receives the 40 clauses: this skill's fresh-eyes sub-agent is `ui-ux-designer`, and `.claude/agents/ui-ux-designer.md` carries `SYNC:ui-ux-design-principles` in its own definition. **Do NOT add the clauses to the injection template** — route them through the specialist agent instead. — why: a shared template that also feeds security and integration reviewers is the wrong layer for UI-only clauses.

The full backend-OOP treatise (anemic models, primitive obsession, value objects, repo leakage) does not apply to UI review and is intentionally not carried here. UI-relevant essence: (1) **extract repeated component lifecycle** — 3+ forms/list views reimplementing loading/dirty/submit/pagination → base component / hook / composable / mixin; (2) **keep derivations, formatting, and validation off the template** — move them onto the model / store / view-model / API service, not inline in the component.

<!-- SYNC:design-patterns-quality -->
> **Design Patterns Quality** — Priority checks for every code change:
>
> 1. **DRY via OOP:** Identify classes/modules with the same purpose, naming pattern, or lifecycle. Apply your knowledge of the project's language/framework to determine the idiomatic abstraction (base class, mixin, trait, protocol, decorator). 3+ similar patterns → extract to shared abstraction.
> 2. **Right Responsibility:** Logic in LOWEST layer (Entity > Domain Service > Application Service > Controller). Never business logic in controllers.
> 3. **SOLID:** Single responsibility (one reason to change). Open-closed (extend, don't modify). Liskov (subtypes substitutable). Interface segregation (small interfaces). Dependency inversion (depend on abstractions).
> 4. **After extraction/move/rename:** Grep ENTIRE scope for dangling references. Zero tolerance.
> 5. **YAGNI gate:** Recommend extraction when 3+ similar patterns exist OR an evidenced consumer boundary/substitution need justifies it; do not create patterns for hypothetical future use.
> 6. **Purpose-oriented naming protocol:** Name public or cross-layer abstractions by the capability, domain purpose, or contract consumers rely on—not the current provider, SDK, framework, database, or transport. `IStorage`/`Storage` → `AzureBlobStorage`; use `IAzureStorage` only when Azure-specific semantics are intentionally part of the contract. — why: provider-coupled names make an implementation replacement look like a contract change.
> 7. **Contract-fit check:** Read callers and every implementation before judging a name; narrow an over-broad abstraction (`IObjectStore`, `DocumentStore`) instead of rewarding a generic name that lies about behavior. — why: a name cannot be validated from the declaration alone.
> 8. **Mechanism/generic-name smell:** Treat `Manager`, `Helper`, `Utils`, `Data`, `Thing`, `Service`, `Interface`, type decorations, and unexplained abbreviations as review signals—not automatic defects; flag them only when they hide purpose, scope, or responsibility. — why: blanket word bans replace judgment with another naming convention.
> 9. **Concrete implementation names:** Provider, strategy, transport, or test-double names are valid on concrete types when they distinguish real behavior (`AzureBlobStorage`, `InMemoryStorage`, `RetryingStorage`); keep those details out of the caller-facing contract unless the contract promises them. — why: implementation names should explain the selected behavior while callers depend on stable semantics.
> 10. **Language convention:** Preserve local interface syntax and naming style; `.NET` `I` prefixes and Google TypeScript's unmarked interfaces are both valid local conventions. — why: purpose-oriented naming is universal, marker syntax is ecosystem-specific.
>
> **Anti-patterns to flag:** God Object, Copy-Paste inheritance, Circular Dependency, Leaky Abstraction.
>
> **Serial Attention for Design Quality** — Scan one quality dimension at a time (serial passes), not all concerns at once. — why: split attention misses violations that single-focus passes catch.
>
> 1. **Identify applicable dimensions** — Based on the code's language, domain, and patterns, determine which quality dimensions apply: DRY, SOLID principles (SRP/OCP/LSP/ISP/DIP), OOP idioms, cohesion/coupling, GRASP, Law of Demeter, CQRS invariants, etc. Your list is NOT fixed — derive from what the code actually does.
> 2. **One focused pass per dimension** — Dedicate single-focus attention to EACH dimension in sequence. Do NOT mix concerns across passes.
> 3. **Threshold: 3+ similar patterns = MANDATORY extraction** — Not optional suggestion. Flag as mandatory structural fix requiring action.
> 4. **2+ violations of same kind = structural finding** — Report as "pattern problem" needing architectural resolution, not a list of individual instances.

<!-- SYNC:double-round-trip-review -->
> **Validated-Finding Fix + Full Re-Review Loop** — Re-review is triggered by a validated finding fix cycle or an explicitly declared independent-pass minimum, not by a round number alone. Review purpose: `review → validate findings → fix validated findings that block the current round → full re-review` until a complete review pass clears the round's exit bar (see **Severity floor** below). **A clean review ENDS the loop once the persisted `minRounds` is met (default 1); an explicitly declared minimum such as 2 still requires that independent pass.**
>
> _aka **Self-Review Convergence Loop**._ The name is historical — there is **NO 2-round cap**; "double-round-trip" only means a validated-finding fix cycle forces at least one fresh re-review. It runs until the current round's exit bar is clear (round 1: zero findings; round 2+: zero CRITICAL/HIGH/MEDIUM, LOW deferred), bounded by the **3-round ceiling** below.
>
> **Round cap — 3 rounds MAX (a ceiling, NEVER a target).** A clean pass ENDS the loop at ANY round once `round >= minRounds` — round 1 included with the default minimum; the cap never obliges extra rounds. Hitting round 3 with blocking findings still open (severity floor applied) → **STOP and escalate by asking the user directly** with the still-open findings listed; NEVER emit a silent "good enough" PASS on cap exhaustion, and NEVER let the cap substitute for the clean-review requirement. The 2-repeated-no-progress blocker rule stays an EARLIER exit — escalate at whichever trips first.
>
> **Severity floor — from round 2, LOW stops blocking.** The exit bar tightens after the first review pass, so the loop converges on consequence instead of spinning on polish:
> Define one predicate everywhere: `blocking_findings(round, findings)` returns all validated findings in round 1 and only validated CRITICAL/HIGH/MEDIUM findings in rounds 2–3. A binary gate (test-green, security must-fix, required artifact) is exempt only when its owning invariant explicitly says so; in practice binary gates always remain blocking when they fail.
>
> | Round | Exit bar — loop ENDS when the fresh full review has… | Must be fixed to continue |
> | --- | --- | --- |
> | 1 | zero validated findings at ANY severity | CRITICAL · HIGH · MEDIUM · LOW |
> | 2–3 | zero validated CRITICAL / HIGH / MEDIUM findings — **LOW-only clears the severity bar** | CRITICAL · HIGH · MEDIUM only |
>
> From round 2 onward LOW findings are **NOT required to be fixed**: a round whose validated findings are ALL LOW **ENDS the loop once the persisted minimum is met** — do not open another fix/re-review round for them. Severity tiers are `SYNC:severity-rubric` (CRITICAL block-merge · HIGH must-fix · MEDIUM must clear the current round · LOW record/defer); round 1 remains strict, so a LOW found initially is still validated and fixed when warranted before the floor can apply.
>
> **Severity-floor rules:**
>
> - **Never silently drop a deferred LOW.** Every unfixed LOW is listed in the final report under `## Deferred LOW Findings (severity floor, round ≥2)` with file, line, and description, so the owner can schedule it. Dropping it from the report is a protocol violation, not a clean pass.
> - **Never re-tier a finding to trigger the exit.** Downgrading a real CRITICAL/HIGH/MEDIUM to LOW so the loop can end is a FALSE PASS. Severity is set by consequence per `SYNC:severity-rubric` before the round bar is applied — never after, and never with the exit in view. — why: a floor that can be reached by relabeling is not a floor.
> - **The floor bounds the loop, not the standard.** It ends *iteration*; it never authorizes shipping a known CRITICAL/HIGH/MEDIUM, and it never lowers the finding-survival bar that admits a finding in the first place.
> - **The floor never applies to a hard gate.** Test-green gates (a suite must actually pass), security must-fix gates, and any gate whose criterion is binary rather than severity-rated are unaffected — a failing test is a failure, not a LOW finding.
>
> **Universal scope (any new output/judgment):** any newly produced output or judgment gets **≥1 self-review**; any **new judgment** gets **≥1 `$why-review --validate-findings` pass**; anything flagged to re-check is re-checked **≥1 time** — before that output is treated as final. This loop is the default convergence contract for ANY work-producing skill, not review skills only.
>
> **Routing invariant (author-facing):** a skill that validates findings MUST route them through `$why-review --validate-findings` (the terminal validator) — NEVER fork an inline finding-validation. Routing through why-review is what makes the finding-survival bar and this loop apply; the `verify-review-validate-coverage` sensor enforces this exact route mechanically.
>
> **Round 1:** Main-session review. Read target files, build understanding, note issues. Output findings + verdict (PASS / FAIL).
>
> **Decision after Round 1:**
>
> - **No issues found (PASS, zero findings)** → review ENDS if `round >= minRounds`; otherwise perform the explicitly required independent pass. Do NOT invent a confirmation pass.
> - **`blocking_findings(round, findings)` is non-empty** → run the active review skill's findings-validation gate first; for review skills the default gate is `$why-review --validate-findings <report-path>`. Fix only validated findings that block the current round, then restart the full review protocol from the beginning with a fresh task breakdown.
>
> **Fresh full re-review after every fix cycle:** Re-run the whole review protocol over the current full target. When sub-agents are part of that protocol, spawn NEW `spawn_agent` calls — never reuse prior agents. Reviewers re-read ALL files from scratch with ZERO memory of prior rounds. See `SYNC:fresh-context-review` for the spawn mechanism and `SYNC:review-protocol-injection` for the canonical Agent prompt template. Each fresh full review must catch:
>
> - Cross-cutting concerns missed in the prior round
> - Interaction bugs between changed files
> - Convention drift (new code vs existing patterns)
> - Missing pieces that should exist but don't
> - Subtle edge cases the prior round rationalized away
> - Regressions introduced by the fixes themselves
>
> **Loop termination:** After each full re-review, repeat the same decision against **that round's exit bar**: bar cleared and persisted minimum met → END; blocking findings remain → validate findings → fix → restart from the first review phase. Round 1 clears only on zero findings at any severity; **from round 2 the bar is zero CRITICAL/HIGH/MEDIUM, so a LOW-only round ENDS the loop once the persisted minimum is met** (deferred LOWs go in the report). Capped at **3 rounds**. Escalate by asking the user directly at whichever comes first: the same validated finding repeats for 2 full invocations with no progress · a fix requires product/owner input · round 3 completes with CRITICAL/HIGH/MEDIUM still open. NEVER loop past 3 rounds, and NEVER convert cap exhaustion into a PASS.
>
> **Rules:**
>
> - A clean Round 1 ENDS the review when `minRounds=1`; an explicitly declared `minRounds=2` requires the independent second pass
> - From round 2 on, a round whose validated findings are ALL LOW ENDS the loop once the persisted minimum is met — never open round N+1 to fix LOW alone; list those LOWs as deferred instead
> - NEVER re-tier a CRITICAL/HIGH/MEDIUM down to LOW to reach the round-2 exit — severity is assigned by consequence before the bar is applied
> - NEVER fix unvalidated findings; validate first using the caller's validation gate
> - Every surviving finding must additionally clear the **finding-survival bar** defined in why-review's Findings Validation Routine (a deliberately higher bar than the generic act-gate — "keep this finding?" is a stricter question than "act on this evidence?"); a finding below the bar is demoted or dropped, not kept
> - NEVER skip the full re-review after a fix cycle (every fix invalidates the prior verdict)
> - NEVER reuse a sub-agent across rounds — every iteration that uses sub-agents spawns NEW Agent calls
> - Main agent READS sub-agent reports but MUST NOT filter, reinterpret, or override findings
> - The 3-round cap NEVER replaces the clean-review requirement — it bounds runaway looping, it does not authorize shipping an un-clean review; a clean pass ends the loop early once the persisted minimum is met, and cap exhaustion escalates rather than passes
> - Enforce the round cap of 3 alongside the 2 repeated-no-progress blocker rule; both are escalation triggers, neither is a completion criterion
> - Persist completed rounds, repeated blockers, findings and the explicit minimum in the owning run's `review-policy.cjs` record. Resume that record after interruption; target changes invalidate evidence and acceptance but preserve the bounded round budget. In-flight attempt IDs may be session-local; they do not replace or reset completed-round state
> - Final verdict must incorporate ALL rounds executed
>
> **Report must include `## Round N Findings (Fresh Sub-Agent)` for every round N≥2 that was executed, plus `## Deferred LOW Findings (severity floor, round ≥2)` whenever the loop ended on the round-2+ bar with LOWs still open.**

> Each batch sub-agent receives: its full file list; `SYNC:category-review-thinking` as its primary thinking model — derive each category's concerns from first principles, NOT a fixed checklist (if the consuming skill does not carry that block, apply category-first thinking directly); project reference docs relevant to its concern (discover via `*patterns*`, `*conventions*`, `*style-guide*`); cross-reference verification instructions (counts, tables, links). All batch agents run in parallel and write findings to `plans/reports/` (per `SYNC:task-tracking-external-report`); reducers read from disk, never from memory.
>
> **Step 3 — Reduce.**
>
> - **Flat reduction (rung 2, ≤6 categories AND ≤40 files):** the orchestrator collects each batch report, cross-references counts/tables/contracts ACROSS batches, detects gaps visible only across categories (feature in code but missing from docs; new API endpoint with no client call), and consolidates into one categorized holistic report.
> - **Hierarchical reduction (rung 3, > 6 categories OR > 40 files):** insert a mid-tier — each concern gets ONE synthesizer agent that reads only its own batch reports and emits a single concern-synthesis. The orchestrator reads the **concern-syntheses (~5)**, never the raw batch reports — keeping the reducer's context O(#concerns), not O(#files).
> - **Cross-concern interaction pass (mandatory at rung 3 — closes the synthesis-tier blind spot):** concern-siloed synthesis can drop an interaction spanning two concerns AND two batches (tainted source in data-layer/batch 7 → sink in api/batch 3). So: (a) each concern-synthesizer MUST emit an explicit **"cross-concern interaction candidates"** list — entities/symbols/contracts it touched that plausibly bind to another concern (shared DTOs, event names, table/collection names, exported symbols); (b) the orchestrator MUST run the Step-3 cross-reference/gap step **over those candidate lists across all concern-syntheses**, not only within a batch, before concluding. Without this pass the tier trades completeness for context-bounding on exactly the large diffs it targets.
>
> **Step 4 — Holistic assessment.** With all findings combined, judge: overall coherence as a unified intent; cross-category sync (docs match code? contracts match callers?); risk areas where categories interact; missing doc/spec updates for changed artifacts.
>
> **No silent truncation.** If any cap forces sampling or a batch is dropped for budget, ANNOUNCE the dropped/sampled scope explicitly — bounded coverage must never read as complete coverage.

<!-- SYNC:severity-rubric -->
> **Severity Rubric** — Classify every finding by consequence, not by effort, reviewer preference, or how annoying the fix is. One scale applies to every review, skill, agent, workflow, and host so a tier has the same meaning everywhere. Choose the highest credible consequence supported by evidence; do not lower a tier to make a round pass.
>
> **Finding vs observation (required):** An observation becomes a finding only when it names the affected user/system/data/contract, the shipped consequence, the evidence location, and the normalized tier. `INFO`, advice, preference, duplicate wording, or an unsubstantiated concern is not a finding and must not reopen a loop. If the concern might affect a required behavior or gate but evidence is incomplete, emit `NOT VERIFIABLE` with the missing evidence and keep it unresolved; never silently convert uncertainty into LOW.
>
> | Severity | Action | Definition and examples |
> | --- | --- | --- |
> | CRITICAL | Block immediately; escalate | Immediate material risk if shipped: authentication/authorization or safety bypass; secrets/PII exposure; irreversible destructive action; data loss/corruption; or a silent failure on a critical path. A failed binary gate that makes the result untrustworthy is represented as a separate synthetic blocker by the executable policy (not as an ordinary severity judgment). |
> | HIGH | Must fix before PASS/merge | Material correctness or contract risk: wrong behavior on a supported path; violated business/data invariant; meaningful privacy or authority gap; breaking API/schema/compatibility change; likely harm to users/downstream systems; or a missing proof for a behavior-changing fix. |
> | MEDIUM | Must clear the current round; escalate if the fix needs an owner decision | Bounded but consequential risk: an edge case, resilience/observability/testability/maintainability gap, credible future defect, or local architectural drift whose impact is real but not immediate material loss. An explicit follow-up records the escalation/residual risk; it does not make an open MEDIUM a clean pass. |
> | LOW | Record and defer; never open another fix/re-review round from round 2 onward | Non-blocking polish with no credible present correctness, security, privacy, authority, availability, or data-integrity impact: wording/formatting, minor documentation or convention drift, optional defensive cleanup, or a cosmetic/refinement suggestion. |
>
> **Consequence decision tree (apply in order):** (1) Is a binary gate failed? Keep it as a separate hard blocker (the executable helper represents it as synthetic CRITICAL); do not use the ordinary severity label to hide what failed. Otherwise, would shipping permit immediate material security/safety/authority harm, irreversible destruction, data loss/corruption, or a critical-path silent failure? → **CRITICAL**. (2) Otherwise, does a supported path, invariant, public contract, privacy/authority boundary, compatibility promise, or behavior-changing proof fail with material user/downstream impact? → **HIGH**. (3) Otherwise, is there a bounded but consequential edge, resilience, observability, testability, maintainability, or architectural gap with a credible impact? → **MEDIUM**. (4) Otherwise, is the evidence sufficient to show only non-blocking polish with no credible present material impact? → **LOW**. (5) If the evidence needed to choose between steps 1–4 is missing, → **NOT VERIFIABLE**, not LOW. When multiple tiers fit, select the highest credible consequence; effort, implementation cost, reviewer discomfort, frequency alone, and proximity to the round cap never decide the tier.
>
> **Boundary examples (normalize before applying the round predicate):** an auth bypass, exposed secret/PII, destructive command without an authority gate, or failed required test/generation/parity gate is **CRITICAL**; a wrong supported response, broken invariant/API/schema, meaningful privacy/authority defect, or unproven behavior-changing fix is **HIGH**; a bounded retry/timeout/alert/testability gap or credible maintainability drift is **MEDIUM**; a typo, formatting inconsistency, optional cleanup, or cosmetic suggestion proven not to affect present behavior is **LOW**. A missing fact about any of those boundaries is **NOT VERIFIABLE** until evidence or an explicitly documented residual-risk decision exists.
>
> **Classification procedure (required for every finding):** (1) state the affected user, system, data, contract, or gate; (2) assess consequence if the issue ships; (3) assess exposure/likelihood and reversibility/detectability; (4) select the highest tier justified by those facts; (5) cite `file:line` or equivalent evidence and a confidence percentage. Effort, implementation cost, reviewer discomfort, and proximity to the round cap are never severity inputs. `NOT VERIFIABLE` is a pending evidence state, not one of the four tiers and never a LOW escape hatch: if the unresolved claim could affect required behavior, security, privacy, authority, availability, data integrity, or a binary gate, it remains an open evidence blocker until resolved or explicitly owner-accepted with documented residual risk. Classify an item LOW only when evidence supports the absence of credible present material impact.
>
> **Hard-gate rule:** Binary gates (tests, required artifacts, security must-fix checks, generated parity, policy compliance) are not ordinary severity-rated findings. The executable helper records a failed gate as a synthetic CRITICAL blocker solely so one predicate can carry it; the report must still name the gate and failure evidence. A failed gate blocks at every round, including when all ordinary findings are LOW; never disguise a failed gate as LOW.
>
> **Score-based skills** map their numeric scale onto these tiers — do not invent a parallel vocabulary:
>
> - **0-2 criterion scoring** (e.g. production-readiness-review): `0` = CRITICAL/HIGH (criterion unmet, blocks readiness), `1` = MEDIUM (partial, consequential gap), `2` = pass (no finding). If the criterion is only polish, use LOW rather than forcing a `0`.
> - **Two-axis scoring** (e.g. performance-review, impact × likelihood): high impact + high exposure → CRITICAL/HIGH; material impact with bounded exposure → HIGH/MEDIUM; low impact and low exposure → LOW. Record the axes and why the selected tier is the highest credible consequence.
> - **Scorecards / `/20` grades** (e.g. architecture-scalability-review): the aggregate score and verdict band are separate from finding severity. A sub-80 area is evidence to investigate, not an automatic CRITICAL/HIGH/MEDIUM/LOW label; classify each underlying gap by the consequence decision tree and keep advisory score deductions separate from blocking findings.
>
> **Domain-vocabulary normalization (mandatory):** Specialized skills may keep a local reporting vocabulary, but it MUST feed this same four-tier round predicate — never a second severity system:
>
> - `BLOCKED`, `HARD FAIL`, or `FAIL` is a blocking local verdict, not an automatic CRITICAL label. Classify the underlying consequence as CRITICAL when it is an immediate material risk or failed binary gate; otherwise classify it as HIGH or MEDIUM with evidence, while preserving the local block until the owning gate is satisfied.
> - `WARN` is not permission to ignore a finding. Map it to MEDIUM when the gap is consequential, to LOW only when evidence supports no credible present material impact, or upward to HIGH/CRITICAL when the consequence warrants it. `PASS`/compliant is not a finding.
> - UI `P0`/`P1`/`P2`/`P3`/`P4` map to CRITICAL/HIGH/MEDIUM/LOW/LOW respectively as a starting point; override upward only when the evidence shows a higher shipped consequence. A P0/P1 accessibility or task-completion floor remains a blocking gate even when a local UI report calls it a priority rather than a severity.
> - Numeric SRE/readiness or impact/likelihood scores are evidence inputs, not replacement tiers. Emit the score, the consequence, and the normalized CRITICAL/HIGH/MEDIUM/LOW tier together. `INFO`/advisory observations are not findings unless the evidence shows a material consequence.
>
> A finding's tier drives the gate: CRITICAL/HIGH/MEDIUM remain actionable and blocking under the round policy; LOW may be tracked as a follow-up and, from round 2, does not by itself justify another fix/re-review. An owner decision may explain or schedule an open MEDIUM but does not turn it into a clean pass; owner acceptance never makes a failed binary gate pass and must record scope, rationale, and residual risk.

> **Category Review Thinking** — A thinking framework for reviewing any category of changed files. NOT a fixed checklist — derive concerns from domain knowledge; the examples are starting points only. Your knowledge of the category exceeds any list here — trust it.
>
> **Step 1 — Understand the category's role.** What is this category responsible for in the overall system? What invariants must it uphold? What are its consumer contracts (who depends on it, what do they expect)?
>
> **Step 2 — Read project conventions for this category.** Search for reference docs, style guides, ADRs, or READMEs specific to this area. Grep 3+ existing similar files — extract naming conventions, structural patterns, shared base classes. If no docs exist, derive conventions empirically from existing code.
>
> **Step 3 — Derive concerns from first principles.** Apply all that are relevant; expand beyond this list based on the actual category:
>
> - **Correctness:** Does the logic match the intent? Trace happy path AND error path.
> - **Boundary contracts:** Are interfaces/APIs/events/protocols honored? No implicit coupling introduced?
> - **Project conventions:** Does new code follow the patterns found in Step 2? Evidence-confirmed, not assumed.
> - **Security:** Auth enforced at every entry point? Input validated at boundaries? No secrets in the diff?
> - **Performance:** Unbounded operations? N+1 patterns? Blocking calls in async context? Unindexed queries?
> - **Maintainability:** DRY? Single responsibility? Complexity within reason? Names reveal intent?
> - **Boundary naming:** When the category exposes public or cross-layer types, APIs, events, or modules, verify that names describe the capability, domain purpose, or contract rather than the current provider/framework/transport; concrete adapters may carry those details. Check callers and implementations before flagging a name, and treat generic names (`Manager`, `Helper`, `Utils`, `Data`) as signals rather than automatic violations.
> - **Test coverage:** Are the changed paths covered by tests? Are existing tests still valid after the change?
> - **Documentation:** Do related docs, specs, or READMEs reflect the changes?
>
> **Step 4 — Create sub-tasks and execute.** For each identified concern: create a task tracking sub-task, work through it with `file:line` evidence, mark done. No findings without proof.
>
> **Illustrative concern examples by category type** (not exhaustive — trust your knowledge beyond this):
>
> - _Server-side logic:_ handler/service structure conventions, validation layer placement, side-effect isolation, cross-service boundary enforcement, data-access layer separation, error propagation strategy
> - _Client-side logic:_ component lifecycle management, resource cleanup (subscriptions, listeners, timers), state management patterns, API integration layer separation, reactive stream composition
> - _Data/Schema:_ migration reversibility (rollback script), lock impact on table volume, backfill idempotency, index coverage for query patterns, deployment ordering
> - _Configuration:_ present in ALL environments? No secrets in diff? App fails fast if config missing (not silently null)? Documented in setup guide?
> - _Infrastructure:_ dev/prod parity? No hardcoded dev values (localhost, debug flags)? Pinned image/dependency versions? CI/CD secret requirements documented?
> - _Styles/Assets:_ follows project naming conventions? Uses design variables/tokens (no hardcoded magic values)? Correct scope (no global side effects from component styles)?
> - _Documentation:_ accurate? Links valid? Examples still match current code/behavior? Covers new scenarios?
> - _Tests:_ assertions verify specific outcomes (not just "no exception")? Idempotent (repeatable N times)? Covers edge cases, not just happy path?
> - _Security artifacts:_ all code paths reach the gate? Negative tests exist (unauthorized denied)? Both enforcement AND display control updated?
> - _Build/Tooling:_ rule changes apply consistently? No exceptions that silently swallow violations? Impact on CI runtime documented?

> 4. **After execution/verification:** append an Iteration Log entry — result, evidence references (`file:line`, command output, report path), remaining gaps.

>
> 1. **Is there any trade-off?** Name what it SACRIFICES. "None" / "pure win" is an unfinished analysis, NOT an answer — to claim none, state which dimensions you checked and why each is unaffected: future change cost · complexity · performance/latency · memory/cost · coupling · reversibility · migration burden · operational load · blast radius · security posture · testability · team skill/ramp · delivery time · UX.
> 2. **Is it worth it?** Weigh gain against sacrifice EXPLICITLY — what is gained (with a metric) · what it costs · WHO pays · WHEN it comes due — then emit **WORTH IT / NOT WORTH IT / UNCLEAR**. "Better" with no metric and no cost FAILS this question. NOT WORTH IT → withdraw or replace the recommendation, never keep it as-is.
> 3. **Is the trade-off material enough to CONFIRM WITH THE USER?** A material trade-off is the user's call, never yours. **MATERIAL** when ANY holds: irreversible / one-way door (data migration, public contract, storage format, vendor lock-in) · cost shifted onto someone else (another team, ops/on-call, future maintainer, end user) · one quality attribute traded for another (correctness↔speed, security↔convenience, latency↔cost, simplicity↔flexibility) · a boundary crossed (client↔server tier, service contract, event contract, shared library) · a high-consequence path (auth, money, data integrity, breaking change, High/Medium residual risk) · the worth-it verdict is UNCLEAR.
>
> **MATERIAL → STOP and confirm by asking the user directly BEFORE the verdict stands** — state the trade-off, both options, what each sacrifices, and your recommendation. **NOT material →** record it inline with a one-line justification and proceed.
>
> **Non-asking execution contexts — ESCALATE BY HANDOFF, never by silence.** ask the user directly reaches only the main interactive agent: a sub-agent cannot ask the user, and a terminal/verdict-only mode asks nothing by design. When you are running in such a context, the obligation is **redirected, never waived** — do ALL of: (a) complete questions 1 and 2 normally; (b) decide materiality and record it in the Trade-Off Assessment row with `confirmed? = NO — cannot ask from this context`; (c) **name the unconfirmed MATERIAL trade-off explicitly in your returned summary/verdict so the CALLER (or parent orchestrator) escalates it by asking the user directly on your behalf** — a material trade-off mentioned only inside a report file on disk is NOT a handoff; (d) do not emit an unqualified PASS — mark the verdict as carrying an unconfirmed material trade-off, so the caller's gate stays closed until the user answers. The caller inherits the escalation duty the moment it reads your return.
>
> This carve-out is about **reachability, not convenience**: it applies ONLY where the tool genuinely cannot reach the user (spawned sub-agent, terminal validate/verdict-only mode, non-interactive/headless run). It is NEVER a licence to skip the question, to self-approve a one-way door, or to downgrade materiality because asking is inconvenient — if you CAN ask, you MUST ask.

>
> **1.0 Visual Hierarchy & Layout**
>
> - `UI-1.1` One focal point per screen. Two elements competing for first read → demote one.
> - `UI-1.2` Signal order: size → weight → colour → position. Use the cheapest signal that works before adding another.
> - `UI-1.3` Group by proximity, NEVER by border. Whitespace separates cleanly; boxes inside boxes do not.
> - `UI-1.4` Align to a shared edge. Every unexplained indent reads as an accident.
> - `UI-1.5` Design the empty, loading and error state FIRST. The full state is the easy one.
>
> **2.0 Typography**
>
> - `UI-2.1` Max 2 families, 3 weights each. More variety reads as inconsistency, not range.
> - `UI-2.2` Body text 16px web, 17px mobile. NEVER below 14px for anything a user must read.
> - `UI-2.3` Line length 45–75 characters. Constrain the measure, not the container.
> - `UI-2.4` Leading scales inversely with size: 1.5 body, 1.1–1.2 display.
> - `UI-2.5` Fixed type scale — 6 named steps shared with engineering. NEVER one-off sizes.
>
> **3.0 Colour & Contrast**
>
> - `UI-3.1` Contrast 4.5:1 text, 3:1 UI edges. Measure it — NEVER judge by eye on a bright screen.
> - `UI-3.2` One accent, one job. An accent that is everywhere points at nothing.
> - `UI-3.3` Colour NEVER carries meaning alone — pair it with an icon, label or position.
> - `UI-3.4` Dark mode is NOT inverted light mode. Lift surfaces to signal elevation; soften pure-white text.
>
> **4.0 Spacing & Grid**
>
> - `UI-4.1` One spacing unit, multiplied — 4px or 8px base; every gap a multiple of it.
> - `UI-4.2` Space belongs to the container, not the child. Use `gap`; reserve margins for exceptions.
> - `UI-4.3` Tighter inside, looser between — inner padding always smaller than the gap to the next group.
> - `UI-4.4` Breakpoints follow content, not devices. Break where the layout stops working.
>
> **5.0 Interaction & Feedback**
>
> - `UI-5.1` Every action gets a response under 100ms, even when the result takes longer.
> - `UI-5.2` Specify all 5 states — default, hover, focus, active, disabled — plus loading where it applies.
> - `UI-5.3` Prefer undo over confirmation. Confirm ONLY what cannot be reversed.
> - `UI-5.4` Motion clarifies cause and effect: 150–250ms, ease-out, honours reduced-motion.
> - `UI-5.5` Keep the visible focus ring. Restyle it if it clashes; NEVER remove it.
>
> **6.0 Navigation & IA**
>
> - `UI-6.1` Every screen answers: where am I, what's here, where next.
> - `UI-6.2` Max 5 top-level destinations. Depth beats a crowded first level.
> - `UI-6.3` Label by the user's word, not the internal one. Team vocabulary is not a taxonomy.
> - `UI-6.4` Every state deserves a URL or a back path. Deep links and hardware back must land somewhere sensible.
>
> **7.0 Forms & Input**
>
> - `UI-7.1` Ask for less. Every field needs a reason it exists today.
> - `UI-7.2` Labels stay visible. Placeholders are hints, NEVER labels.
> - `UI-7.3` Validate on blur, not on keystroke. Errors sit next to the field and say how to fix it.
> - `UI-7.4` Match keyboard to data type — correct input type, autocomplete and autocapitalise on every field.
> - `UI-7.5` NEVER lose entered data. Preserve input across errors, navigation and refresh.
>
> **8.0 Mobile & Touch** _(mobile/touch surfaces)_
>
> - `UI-8.1` Hit target ≥44×44pt, 8px apart. The target may exceed the visible icon.
> - `UI-8.2` Primary actions in the bottom third — that is where the thumb lives.
> - `UI-8.3` Gestures are shortcuts, NEVER the only route. Anything swipeable is also tappable.

Then the **project's design-system / SCSS / frontend-pattern docs and accepted ADRs** — a house style IS an intentional identity, and re-deciding it per feature is the incoherence this gate prevents. Then these clauses. A genuine conflict is SURFACED to the user with both sides, NEVER resolved silently.
>
> **Relationship to `UI-1.1`–`UI-9.4`:** a different question, no overlap — the 40 clauses ask _"is this usable, accessible, consistent?"_ (a measurable floor); this gate asks _"is this THIS product's interface, or the one any generator would emit for any brief?"_. A surface can pass all 40 clauses and still be a template. BOTH bind; where they touch (type scale, colour, motion timing) the clause sets the floor and this gate picks the value.
>
> - `DD-1` **Ground it in the subject matter.** Before designing, name the concrete subject, the audience, and the design's primary job — and CONFIRM with the user when the brief is silent. Distinctive choices come FROM the subject's industry, materials and vernacular; they are never taste applied on top. **Test: if the palette, type and layout would fit a different product unchanged, there is no identity yet.**
> - `DD-2` **Every choice carries a WHY.** "It's common", "it's clean", "users expect it" are not reasons. A decision with no articulable reason is a default that arrived unnoticed. Defaults hide in what feels like infrastructure — typography, navigation, data display, and TOKEN NAMES. **Token-name test: someone reading only your CSS variables should be able to guess what product this is** (`--ink`/`--parchment` evoke a world; `--gray-700`/`--surface-2` evoke a template).
> - `DD-3` **Two passes, and the review pass is mandatory.** (1a) Write a compact **design plan** — Colour (4–6 named hex values) · Type (families + roles + scale) · Layout (one-sentence prose + ASCII wireframes to compare alternatives, including alignment: left/centre/justified) · Principles (what makes THIS page unique). (1b) **BLOCKING generic test — before any code:** work through a similar prompt and see whether you arrive somewhere similar; **any part that reads like the generic default for any comparable page rather than a choice for THIS brief gets REVISED, and you state what you changed and why.** Then (2a) build the REVISED plan, (2b) critique. — why: writing a plan and going straight to code reproduces the default, because the plan came from the same patterns the code will.
> - `DD-4` **Audit every FREE axis against the generated-design tell catalog** (`[model-knowledge]`, calibration not prohibition — each trait is legitimate for SOME brief): **T1** cream `#F4F1EA` + high-contrast serif + terracotta near `#D97757` (Anthropic's own interaction accent — on a user's brief it reads specifically as a tell) · **T2** near-black + one acid-green/vermilion accent · **T3** broadsheet hairline-rule pastiche, zero radius, dense columns · **T4** the SaaS-card kit: identical rounded cards, ONE radius regardless of hierarchy, the same `rgba(0,0,0,.1)` shadow under each, gradient washes as decoration · **T5** template chrome whatever the subject: tracked-out ALL-CAPS eyebrow above every heading, meta strings joined with middle dots (`A · B · C`), `WORD — fragment` labels with a spaced em dash, tinted near-black (`#0B0B0B`/`#111`) standing in for black, monospace for small data labels, `→` appended to link/button text. **A match is a HYPOTHESIS about a missed decision, never a defect** — promote it only by naming the axis, that the brief left it free, and what the subject suggested instead.
> - `DD-5` **Typography carries the personality.** One family, or two CLEARLY distinct ones — you do NOT need separate display and body faces. Choose deliberately, not the default you would reach for on any project. Set a real scale with intentional weights, widths and spacing. When type is a headline it is an ACTIVE part of the design, not a neutral delivery vehicle. Measure under ~80 characters; serifs tolerate slightly longer lines and want slightly more line-height than sans at the same size. Hierarchy needs weight/tracking/opacity, not size alone. **Avoid the three commonest tells: accenting a single word in a headline (italic/bold/colour) · ALL CAPS labels · an eyebrow label that names the section the heading already names.**
> - `DD-6` **Structure is information, not decoration.** Outlines, borders, numbering, eyebrows, dividers and labels must encode something about the content. **Before adding numbered markers (`01 / 02 / 03`), check the content really IS a sequence** — a stepped process, timeline or ranking. For every device ask: what does this tell the reader that whitespace would not? Nothing → cut it. **Hero:** open with the most characteristic thing in the subject's world, in whatever form fits (headline, image, animation, live demo, interactive moment) — big-number-plus-small-label-plus-gradient is the DEFAULT treatment, so use it only when it is genuinely best here. **Composition:** rhythm over monotone (same card size, same gap, same density everywhere is the sound of no one deciding); proportions must say something you can articulate; one dominant focal point.
> - `DD-7` **Motion sparingly and deliberately.** Non-user-triggered motion draws attention ONLY. One orchestrated moment — a single page-load sequence or one reveal — lands better than scattered effects; **fade-and-slide-up entrances on each section and hover transitions on every card are the generic default and read as generated.** Motion that ANSWERS a person's action (opening, expanding, confirming) is welcome when it shows what changed. Honour `prefers-reduced-motion`.
> - `DD-8` **Spend boldness once, then remove one accessory.** Let ONE element be the memorable thing and keep everything around it quiet and disciplined; cut any decoration that does not serve the brief. **Critique the BUILT page, not just the plan** — composition, craft (density is a decision, not a constant), content coherence, and CSS honesty (negative margins undoing a parent's padding, `calc()` values that exist only as workarounds, absolute positioning to escape layout flow are lies; the correct answer is always simpler than the hack). Take screenshots to review where the environment supports it — a picture is worth 1000 tokens. Then ask "if they said this lacks craft, what would they point to?" and fix that. **Build the quality floor in silently** — responsive, visible keyboard focus, reduced-motion respected, measured contrast, tokens never raw hex or magic numbers — and watch CSS selector specificity, where a type-based selector (`.section`) and an element-based one (`.cta`) most often cancel each other's padding/margin.
>
> **Memory:** vary between briefs — light and dark, families, direction. NEVER converge on the same choice across generations (Space Grotesk, for example). Where the project already has a design system, tokens, or an `interface-system.md`, ADOPT and record it rather than re-deciding; write back any pattern used 2+ times with measurements worth remembering.
>
> **Skip ONLY** when the change has NO user-facing visual surface (backend-only, tooling, docs) — state that reason explicitly so the skip is auditable, not an omission.

> **Words are design content, not decoration** — binds whenever a task authors, changes, or reviews user-visible strings (labels, CTAs, headings, empty/error/loading text, toasts, placeholder content).

>
> Before writing anything, ask what the design needs to SAY and how it can best be said to help the person navigate the experience. Then:
>
> 1. **Write from the end user's perspective.** Name things by what users will understand in simple language, not by how the system is built — a user manages **notifications**, not **webhook config**. Describe what something is or does in plain terms rather than selling it. Being specific and legible to a new user ALWAYS beats being clever.
> 2. **Active voice by default.** A CTA says exactly what happens when it is used: **"Save changes"**, NEVER "Submit".
> 3. **One name per action, across the whole flow.** The button that says **Publish** produces a toast that says **Published**. The vocabulary of an interface is the signposting for someone navigating the product — cohesion and consistency are how people learn their way around.
> 4. **Failure and emptiness give DIRECTION, not mood.** Explain what went wrong and how to fix it, in the interface's voice rather than a person's. **Errors do NOT apologize, and are NEVER vague about what happened.** An empty screen is an invitation to act.
> 5. **Conversational tone, one job per element.** Plain verbs, sentence case, no filler, tone matched to the brand and the audience; let each written element do exactly one job.
> 6. **Real content, never lorem.** When the brief supplies no copy, write plausible strings for the ACTUAL subject. **Coherence check — read every visible string as a user would, checking for truth, not typos:** could a real person at a real company be looking at exactly this data right now, or does the page title belong to one product, the body to another, and the sidebar metrics to a third? A beautifully designed interface with nonsensical content is a movie set with no script.

> **Front-End Design Review Checklist** — the EXECUTABLE review protocol for any artifact carrying a user-facing front-end surface. Full catalog (`A1`…`Q`, ~130 checks with failure signals and default severities): **`.claude/docs/design-review-checklist.md`**. This gate carries the protocol and the triage pass; the file carries the checks.
>
> **Applies when — and ONLY when — the change, plan, or artifact carries a user-facing front-end surface.** A back-end-only diff, a doc edit, or a config change is `N/A`: state that once and move on. NEVER run a UI review on a non-UI change to manufacture coverage. When it DOES apply, **MUST ATTENTION READ `.claude/docs/design-review-checklist.md` and work its sections** — a review that cites a check ID without opening the catalog is asserting, not checking.
>
> **`CL-1` Context before checks (§0.1).** Establish platform · primary user & expertise · primary task · success metric · constraints · review scope · available artifacts. Fewer than four known → state the gap at the top of the report and mark affected findings **low confidence** — why: a check judged against an unknown task is a guess wearing an ID.
>
> **`CL-2` Evidence or nothing (§0.2).** Every finding cites a specific location (screen · element · `file:line`). NEVER invent a measurement — contrast, tap-target size, and load time that cannot be measured from the given artifact are `NOT VERIFIABLE`, never a guessed number. Tag every finding `MEASURED` · `OBSERVED` · `HEURISTIC`. Status values: `PASS` · `FAIL` · `PARTIAL` · `N/A` · `NOT VERIFIABLE`.
>
> **`CL-3` Severity, then a cap (§0.3).** `P0` blocks task completion / loses data / excludes a protected group (ship blocker) · `P1` significant friction or a legal accessibility floor (fix before release) · `P2` measurable inefficiency (next iteration) · `P3` polish (backlog) · `P4` note. Cap the report at the top 10 by severity unless a full audit was requested. A clean section reports "no issues found" — NEVER pad. Every `P0`/`P1` carries a concrete fix.
>
> **`CL-4` Section sweep, in order.** §A core usability heuristics · §B cognitive load & decision design · §C visual design & hierarchy · §D interaction + **the eight screen states** (ideal, empty, first-run, loading, partial, error, offline, maximum-data) · §E information architecture · **§F web / §G mobile / §H desktop — conditional on platform** · §I accessibility (WCAG 2.2 AA; every item `P1` minimum, `P0` when it blocks the task) · §J content & UX writing · §K trust, ethics & privacy (dark patterns are `P0`) · **§L AI & agentic patterns — conditional on the product having AI features** · §M cross-cutting consistency · §N edge-case probes. One focused pass per section — why: a section skipped in the long middle silently becomes an unreported defect class.
>
> **`CL-5` Quick Triage Pass (§P)** when a full sweep is not possible — these 10 catch the majority of serious defects: (1) can a new user complete the primary task unaided · (2) does every action give visible feedback within 400ms · (3) do empty/loading/error states exist AND offer a forward path · (4) is the primary action obvious, singular, reachable · (5) text ≥4.5:1 contrast and focus visible · (6) whole flow completable by keyboard · (7) touch targets ≥44/48px · (8) destructive actions reversible · (9) holds at 320px and 200% zoom · (10) any dark patterns.
>
> **`CL-6` Report shape (§O).** Context (+ known gaps) → Verdict (Ship / Ship with fixes / Do not ship) → What works (2–4 specific strengths, cited) → Findings grouped `P0`→`P3`, each with Location · Evidence + tag · Impact · Principle (checklist ID) · Fix → Open questions → Coverage table. Any `P0` caps the grade at Fail regardless of score; report a score only ALONGSIDE findings, never instead of them.
>
> **Precedence and no-double-counting.** The project's design-system / SCSS / frontend-pattern docs and accepted ADRs OUTRANK this checklist; the brief's stated direction outranks aesthetic judgment. A deliberate, documented convention is NEVER a defect — check intent before flagging, and surface a genuine conflict to the user with both sides, NEVER resolve it silently. This checklist is the review PROCEDURE, not a third set of taste rules: `UI-1.1`–`UI-9.4` ask "does it meet the usability floor?", `DD-1`–`DD-8` ask "is this THIS product's interface?", and these checks ask "did the review actually look, with evidence, and rank it?". Where a check restates a `UI-*` or `DD-*` clause, report the defect ONCE under whichever ID the consuming skill already uses.
>
> **For a PLAN or a PLAN REVIEW.** When the plan contains front-end work, the checklist binds the plan's ACCEPTANCE CRITERIA, not a built page: name the platform, the applicable conditional sections (§F/§G/§H, §L), the eight screen states each UI phase must deliver (§D2), and the §I accessibility floor — so the work is specified against the checklist before it is written. A UI phase whose acceptance criteria omit the states and the a11y floor is INCOMPLETE — say so.

- **MANDATORY** Load detail just in time immediately before the first target read/grep/edit/test; hooks may provide a pointer, but a hook event or prior turn is never evidence that the current files were read.

**IMPORTANT MUST ATTENTION** follow declared step order for this skill; NEVER skip, reorder, or merge steps without explicit user approval
**IMPORTANT MUST ATTENTION** for every step/sub-skill call: set `in_progress` before execution, set `completed` after execution
**IMPORTANT MUST ATTENTION** every skipped step MUST include explicit reason; every completed step MUST include concise evidence
**IMPORTANT MUST ATTENTION** if Task tools unavailable, maintain an equivalent step-by-step plan tracker with synchronized statuses
<!-- PROMPT-ENHANCE:STEP-TASK-CLOSING:END -->
<!-- SYNC:double-round-trip-review:reminder -->
- **MANDATORY IMPORTANT MUST ATTENTION** execute the review loop (aka **Self-Review Convergence Loop**): review → validate findings → fix validated blocking findings → full re-review. Round 1 ends only with zero findings and the persisted `minRounds` met; from round 2 onward, zero CRITICAL/HIGH/MEDIUM ends the loop once the persisted minimum is met and LOW findings are recorded as deferred. Any newly produced output/judgment gets ≥1 self-review; any new judgment gets ≥1 `$why-review --validate-findings` pass before it is treated as final.
- **MANDATORY** apply the **severity floor**: round 1 exits on zero findings at any severity; **from round 2 the bar is zero CRITICAL/HIGH/MEDIUM — LOW findings are no longer required to be fixed, so a LOW-only round ENDS the loop once the persisted minimum is met.** List every deferred LOW in the report; NEVER re-tier a real CRITICAL/HIGH/MEDIUM down to LOW to reach the exit, and NEVER apply the floor to a binary gate (test-green, security must-fix).
- **MANDATORY** enforce the **round cap of 3 — a ceiling, NEVER a target**: a clean pass ends the loop once the persisted `minRounds` is met (default 1; explicit 2 requires an independent pass), and round 3 completing with CRITICAL/HIGH/MEDIUM still open → **STOP & escalate by asking the user directly**, never a silent PASS. The 2-repeated-no-progress blocker rule is an earlier exit — escalate at whichever trips first. NEVER loop open-ended.
<!-- /SYNC:double-round-trip-review:reminder -->
<!-- SYNC:goal-contract-satisfaction-loop:reminder -->
- **MANDATORY** Resolve the active Goal Contract BEFORE work (active plan `goal.md` → `plans/goals/{YYMMDD-HHmm}-{slug}/goal.md` → create from current request) and read saved success criteria before editing.
- **MANDATORY** Append iteration evidence after execution; emit a Goal Satisfaction matrix (PASS/FAIL/BLOCKED) before reporting PASS; loop on validated FAIL; escalate repeated no-progress or blockers. NEVER store secrets in goal files.
<!-- /SYNC:goal-contract-satisfaction-loop:reminder -->
<!-- SYNC:trade-off-interrogation-gate:reminder -->
- **MANDATORY MUST ATTENTION ALWAYS ASK THE 3 TRADE-OFF QUESTIONS** — on the thing under review AND on every recommendation you make: (1) **is there any trade-off?** name what it SACRIFICES (change cost · complexity · perf · coupling · reversibility · migration · ops load · blast radius · security · testability · delivery time · UX) — "none"/"pure win" is an unfinished analysis, so state the dimensions checked; (2) **is it worth it?** gain (with a metric) vs cost, WHO pays, WHEN → emit **WORTH IT / NOT WORTH IT / UNCLEAR**; NOT WORTH IT → withdraw or replace it; (3) **is it material enough to confirm with the user?** irreversible/one-way door · cost shifted onto another team/ops/maintainer/user · one quality attribute traded for another · a tier/service/event/library boundary crossed · auth/money/data-integrity/breaking-change/High-or-Medium-risk path · verdict UNCLEAR → **STOP and confirm by asking the user directly BEFORE the verdict**.
- **MANDATORY** A MATERIAL trade-off with no user confirmation can NEVER be PASS; NEVER bury one as a Low-severity note, NEVER decide it silently, and NEVER let delivery or convergence pressure authorize a one-way door. — why: an un-walked-back one-way door is the user's call to make, not the reviewer's.
- **MANDATORY — non-asking contexts escalate BY HANDOFF, never by silence.** ask the user directly reaches only the main interactive agent: a sub-agent cannot ask the user, and a terminal/verdict-only mode asks nothing by design. There the duty is REDIRECTED, not waived — still name the trade-off, still decide materiality, record `confirmed? = NO — cannot ask from this context`, **state the unconfirmed MATERIAL trade-off in your RETURNED verdict/summary so the CALLER escalates it** (a note only in an on-disk report is not a handoff), and never emit an unqualified PASS. Applies ONLY where the user is genuinely unreachable (spawned sub-agent, terminal validate mode, headless run) — if you CAN ask, you MUST ask.

> **Parallel Sub-Agent Dispatch** — Plan parallelism the moment a task breakdown exists, BEFORE executing it — running provably independent tasks sequentially wastes wall-clock. Applies to every multi-step job: workflow steps, planning, batch updates, investigation, research, scans, reviews, doc sync. **Plan execution is metadata-gated, NEVER default-parallel** — fan-out follows ONLY what the plan declares (`PAR`/`SEQ` tags + per-phase write set); an untagged plan runs sequentially — why: a derived write set cannot see cascade or generated writes.
>
> 1. **Tag every task `PAR` or `SEQ`.** `PAR` = inputs exclude every pending task's output AND write set disjoint from every other `PAR`. Else `SEQ` — MUST ATTENTION name the dependency forcing it.
> 2. **Group `PAR` into waves.** No edge between members. Two writers of one file NEVER share a wave. Read-only work (search, investigation, review, research) parallelizes freely.
> 3. **Declare before dispatch:** `Parallel plan: wave 1 = [...] · wave 2 = [...] · SEQ = [...] (reason)`.
> 4. **Spawn each wave in ONE message** — every `spawn_agent` call in one response, NEVER dripped per turn. Route each task to its specialist (`.claude/skills/shared/sub-agent-selection-guide.md`); NEVER `code-reviewer` as catch-all.
> 5. **Brief each sub-agent self-contained:** goal · scope + owned files · reference docs · return contract (summary + `Full report:` path, per SYNC:subagent-return-contract) · incremental persistence to `plans/reports/` (per SYNC:incremental-persistence).
> 6. **Barrier per wave.** Advance ONLY after EVERY member returns (a skipped conditional counts as returned). Merge, mark each task completed/skipped, THEN dispatch the next wave. Mutating steps wait for the barrier.
> 7. **One level deep.** A dispatched sub-agent executes its own brief; further fan-out stays the orchestrator's job unless that agent's `.claude/agents/*.md` definition authorizes it.
>
> **NEVER parallelize:** tasks sharing a write target · a task consuming a pending task's output · trivial single-file work (dispatch overhead > gain) · an order a skill or workflow explicitly fixes · gates awaiting user approval.
>
> **Blocked until:** MUST ATTENTION every task tagged PAR/SEQ with a named reason per SEQ · waves declared + write-set disjointness checked · each wave spawned in ONE message · barrier honored before the next wave.

## Closing Reminders
**IMPORTANT MUST ATTENTION Goal:** Validate UI/frontend changes for the six visual-quality dimensions that break in production but slip past correctness review — long-content overflow & truncation, responsive multi-screen layout (flex-wrap / row-to-column so it stays usable on small devices), flex-grow vs fixed sizing, z-index scale discipline, SCSS/CSS/BEM styling quality, and async UI states & feedback (loading indicator, user-visible error surface, empty state, in-flight disable) — so frontend/UI changes survive real content, responsive layouts, layering, styling conventions, and the loading/error/empty branches before handoff.
**IMPORTANT MUST ATTENTION Workflow:** Phase 0 load project UI rules → Phase 1 determine and filter scope (skip with evidence when no frontend files) → Phase 2 graph blast radius → Phase 3 review Categories 1–6 → Phase 3B run all nine UI/UX design-principles passes → Phase 4 write the compliance verdict → Phase 5 validate findings with `$why-review` → Phase 6 fix only validated findings that block the current round and restart the full UI review (Round 1: all severities; Round 2+: CRITICAL/HIGH/MEDIUM; LOW-only deferred; binary gates always block); batch large scopes and use the UI/UX specialist only as the protocol requires.
**Protocols in force (concise digest of the SYNC/shared blocks this skill carries — MUST ATTENTION honor each canonical body above):**
- **Graph-Assisted Investigation:** Run graph command on key files first.
- **Nested Task Creation:** Expand child phases; link parent when nested.
- **Project Reference Docs Guide:** Read project docs before reviewing.
- **Task Tracking External Report:** Track tasks; persist findings incrementally.
- **Subagent Return Contract:** Sub-agent returns summary plus report path.
- **Critical Thinking Mindset:** Traced proof per claim; never guess.
- **Sequential Thinking Protocol:** Multi-step reasoning; state confidence closer.
- **Evidence-Based Reasoning:** Cite `file:line`; >80% to act.
- **Design Patterns Quality:** DRY, layered responsibility, SOLID; grep dangling.
- **Double Round-Trip Review:** Validate findings, fix only current-round blocking findings, and full re-review until the severity bar is clear (Round 1: zero findings; Round 2+: zero CRITICAL/HIGH/MEDIUM, LOW deferred; binary gates always block).
- **Source-Test Drift Check:** Source changes; inspect affected tests.
- **Understand Code First:** Read code, grep 3+, before changing.
- **AI Mistake Prevention:** verify generated content against evidence, trace downstream references, verify all affected outputs, re-read after context loss, surface ambiguity.
- **Systematic Review Batching:** Large changeset; parallel size-capped batches.
- **Severity Rubric:** Classify by consequence using `SYNC:severity-rubric`; round 1 blocks on every validated finding, rounds 2–3 block only CRITICAL/HIGH/MEDIUM, LOW is recorded/deferred, and failed binary gates always block.
- **Category Review Thinking:** Derive concerns first-principles, never fixed checklist.
- **Parallel Sub-Agent Dispatch:** Tag tasks PAR/SEQ, group PAR into disjoint-write-set waves, spawn each wave in ONE message, barrier before advancing.
**MUST ATTENTION** break work into small tasks using task tracking BEFORE starting
**MUST ATTENTION** resolve and read project UI/styling docs BEFORE reviewing — rules come from docs, not general knowledge
**MUST ATTENTION** SKIP this skill when no files match the project frontend path/extension patterns
**MUST ATTENTION** every violation requires `file:line` proof — NEVER speculate
**MUST ATTENTION** grep 3+ counterexamples before flagging any pattern violation
**MUST ATTENTION** `z-index` with `!important` and chained BEM modifiers are HARD-GATE BLOCKED
**MUST ATTENTION** NEVER mix incompatible project token systems in one file — recommend whichever system the file already imports/uses
**MUST ATTENTION** after validated UI fixes, rerun the full UI review; when that protocol uses a fresh reviewer, use the UI/UX-specialized sub-agent from the local sub-agent selection guide
**MUST ATTENTION** run at least ONE graph command on key files when graph.db exists
**MUST ATTENTION** NEVER fix code — review and report only
**MUST ATTENTION** apply `Think:` reasoning prompt before checking each category — derive violations, don't recite checklists
**MUST ATTENTION** run the Phase 3B UI/UX Design Principles pass — all 40 clauses (`UI-1.1`-`UI-9.4`) as NINE focused passes, one dimension at a time; every finding cites `UI-<clause>` + `file:line` + BLOCKED/WARN severity, and project design-system docs OUTRANK the clauses (genuine conflict → ask the user directly, NEVER resolved silently)
**MUST ATTENTION** use ask the user directly to present next steps after completing review
**Anti-Rationalization:**
| Evasion | Rebuttal |
| ----------------------------------------- | --------------------------------------------------------------------------------------- |
| "Too simple for a UI review" | Simple templates still overflow on a 200-char value. Apply all 6 categories. |
| "Already read the docs" | Show the extracted rule (mixin name, token name) — no recall = no read. |
| "Just flag obvious z-index literals" | Gray areas matter most. Trace the surface's semantic layer before recommending a token. |
| "Fixed width is fine, it looks right" | Looks right at 1440px ≠ usable at 320px. Apply the flex/min-max decision rule. |
| "web-design-guidelines already covers UI" | That is a11y/UX, not the project styling gate. Different scope — do both. |

## Static Prompt Protocol Mirror (Auto-Synced)
Source: `.claude/.ck.json` + `.claude/skills/shared/sync-inline-versions.md` (`:full` blocks) + `.claude/scripts/lib/hookless-prompt-protocol.cjs` (legacy filename; static protocol composer)
## [WORKFLOW-EXECUTION-PROTOCOL] [BLOCKING] Workflow Execution Protocol — MANDATORY IMPORTANT MUST CRITICAL. Do not skip for any reason.
**Generic portability boundary:** Reusable skills and protocol text stay project-neutral; project-specific conventions are discovered from docs/project-config.json and docs/project-reference/. Apply shared AI-SDD from `shared/sdd-artifact-contract.md`. Read `docs/project-config.json` and `docs/project-reference/docs-index-reference.md`, then open the project reference docs named there immediately before the first target read, grep, edit, test, or analysis. For spec, test-case, behavior-change, public-contract, or `docs/specs/` work, route through the local spec docs named by the docs index: `feature-spec-reference.md`, `spec-system-reference.md`, `spec-principles.md`, and `workflow-spec-test-code-cycle-reference.md` when specs/tests/code must stay synchronized. If either file or a required reference doc is missing or stale, auto-run `$project-init` (or the narrow lower-level route such as `$project-config`, `$docs-init`, `$scan-all`, or `$scan --target=<key>`) before ordinary project-specific work. After compaction, resume, delegation, or a material context change, re-read the required docs and state `Reference docs read: ... | Not applicable: ...`; a hook reminder or prior conversation is not proof that the files are loaded. Any supported AI tool may execute when this shared context and local docs are available.
1. **DETECT:** If the prompt starts with an explicit slash skill/workflow command, execute it directly. Otherwise match the prompt against the workflow catalog and skill list.
2. **ANALYZE:** Choose the best option: execute directly, invoke a skill, activate a standard workflow, or compose a custom step combination.
3. **AUTO-SELECT:** Pick the best option yourself. Do not ask the user to choose between direct execution, skill, standard workflow, or custom workflow.
4. **ACTIVATE:** For a selected workflow, call `$start-workflow <workflowId>`; for a selected skill, invoke that skill; for a custom workflow, sequence custom steps directly; for direct execution, proceed with the task.
5. **CREATE TASKS:** task tracking for ALL workflow/skill/custom steps before execution when the selected path has multiple steps.
6. **PARALLELIZE:** Before executing the task list, tag each task `PAR` (independent inputs + write set disjoint from every other `PAR` task) or `SEQ` (name the blocking dependency), group `PAR` tasks into waves, declare the wave plan, and spawn each wave's sub-agents in ONE message — all-return barrier per wave, fan-out one level deep unless a sub-agent's own definition authorizes further fan-out. Sequential-by-default is a defect when tasks are independent; do not parallelize shared write targets, output-consuming tasks, trivial single-file work, ordering a skill or workflow explicitly fixes, or user-approval gates.
7. **EXECUTE:** Advance per the **Workflow Step Advancement & Parallel Phases** rule in your context instructions — model-driven; a sub-agent completion advances a step identically to an inline call; a parallel-phase group is an all-return barrier (advance only after ALL members return, never serialize it)

> 5. Any supported AI tool may plan, implement, review, or verify with synced context; using multiple tools is optional.
> 6. Update `.claude` source first, then sync generated mirrors; do not manually edit `.agents`, `.codex`, or `AGENTS.md`. — why: mirrors are generated artifacts; hand-edits are overwritten on the next sync

## SYNC:ai-sdd-artifact-contract:reminder
- **MANDATORY** Apply `shared/sdd-artifact-contract.md`; keep reusable AI-SDD in `.claude` and local rules in project docs.
- **MANDATORY** Code-to-spec extraction is reference-only until canonical acceptance; any supported AI tool may execute with synced context.
- **MANDATORY** Update `.claude` source before syncing generated mirrors; do not manually edit `.agents`, `.codex`, or `AGENTS.md`.
- **MANDATORY** Missing or stale project config, root instruction files, or required reference docs route project-specific work through `$project-init` or the narrow setup route automatically.
**[TASK-PLANNING] [MANDATORY]** BEFORE executing any workflow or skill step, create/update task tracking for all planned steps, then keep it synchronized as each step starts/completes.
## [LESSON-LEARNED-REMINDER] [BLOCKING] Task Planning & Continuous Improvement — MANDATORY. Do not skip.
Break work into small tasks (task tracking) before starting. Add final task: "Analyze AI mistakes & lessons learned".
**Extract lessons — ROOT CAUSE ONLY, not symptom fixes:**
1. Name the FAILURE MODE (reasoning/assumption failure), not symptom — "assumed API existed without reading source" not "used wrong enum value".
2. Generality test: does this failure mode apply to ≥3 contexts/codebases? If not, abstract one level up.
3. Write as a universal rule — strip project-specific names/paths/classes. Useful on any codebase.
4. Consolidate: multiple mistakes sharing one failure mode → ONE lesson.
5. **Recurrence gate:** "Would this recur in future session WITHOUT this reminder?" — No → skip `$learn`.
6. **Auto-fix gate:** "Could `$code-review`/`$code-simplifier`/`$security-review`/`$lint` catch this?" — Yes → improve review skill instead.
7. BOTH gates pass → ask user to run `$learn`.
**[CRITICAL-THINKING-MINDSET]** Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence >80% to act.
**Anti-hallucination principle:** Never present guess as fact — cite sources for every claim, admit uncertainty freely, self-check output for errors, cross-reference independently, stay skeptical of own confidence — certainty without evidence root of all hallucination.
**AI Attention principle (Primacy-Recency):** Put the 3 most critical rules at both top and bottom of long prompts/protocols so instruction adherence survives long context windows.
**Goal-driven execution:** Define success criteria first, loop until verified, and stop only when observable checks pass.
**Tests verify intent:** Tests must protect business rules/invariants and fail when the protected intent breaks, not only mirror current behavior.
## Common AI Mistake Prevention (System Lessons)
- **Re-read files after context compaction.** Edit requires prior Read in same context; compaction wipes read state. Re-read before editing.
- **Grep for old terms after bulk replacements.** AI over-trusts find/replace completeness. Grep full repo after bulk edits for missed refs in docs/configs/catalogs.
- **Check downstream references before deleting.** Deletions cascade doc/code staleness. Map referencing files before removal.
- **After memory loss, check existing state before creating new.** Compaction wipes prior-work memory. Query current state to resume — never blindly duplicate.
- **Verify AI-generated content against actual code.** AI hallucinates APIs, class names, method signatures. Grep to confirm existence before documenting/referencing.
- **Trace full dependency chain after edits.** Changing a definition misses downstream consumers. Trace the full chain.
- **When renaming, grep ALL consumer file types.** Some file types silently ignore missing refs (no compile error). Search code, templates, configs, generated files.
- **Trace ALL code paths when verifying correctness.** Code existing ≠ code executing. Trace early exits, error branches, conditional skips — not just happy path.
- **Update docs that embed canonical data when source changes.** Docs inlining derived data (workflows, schemas, configs) go stale silently. Update all embedding docs alongside source.
- **Verify sub-agent results after context recovery.** Background agents may finish while parent compacted — grep-verify output, don't trust assumed completion.
- **Cross-check full target list against sub-agent assignments.** Parallel sub-agents by category miss boundary items. Reconcile union of assignments against target list before proceeding.
- **Sub-agents inherit knowledge only from their agent .md definition — use custom agent types, not built-in Explore.** Tool adoption = permission + knowledge + enforcement (numbered workflow step).
- **Persist sub-agent findings incrementally, not as a final batch.** Long sub-agents hit cutoffs before final write — findings lost. Instruct append-per-section to report file.
- **When debugging, ask "whose responsibility?" before fixing.** Trace caller (wrong data) vs callee (wrong handling). Fix at responsible layer — never patch symptom site.
- **Test failure → record a provisional verdict before trace/edit, then investigate.** Use the full five-way taxonomy: SOURCE-WRONG (production violates intent), TEST-WRONG (assertion/setup is stale), TEST-NOT-OPTIMAL (valid but fragile or low-signal test), ENVIRONMENT-BLOCKED (external state prevents a verdict), or AMBIGUOUS (intent/evidence cannot choose safely). Then trace root cause and triangulate against the governing spec (`docs/specs/**` if one exists) AND source. NEVER weaken an assertion, add a skip, relax a timeout, or change source merely to force green.
- **Grep ALL removed names after extraction/refactoring.** Primary file "done" ≠ secondary files clean. Grep entire scope for every removed symbol before declaring complete.
- **Assume existing values are intentional — ask WHY before changing OR flagging one as a defect.** Pattern-matching as "wrong" skips context. Before changing or reporting any constant/limit/flag/cutoff: read comments, git blame, the CALLER's ordering (the guarantee that makes the value correct usually lives in code running immediately BEFORE the cited line), and 2+ sibling call sites of the same convention. A doc stating WHAT without WHY is missing rationale, not proof of a missing guard — and in a validation pass, an accurate `file:line` citation proves the transcription, never the defect.
- **Verify ALL affected outputs, not just the first.** One build green ≠ all green. Multi-stack changes (backend/frontend/tests/docs) require verifying EVERY output.
- **Evaluate fit before copying a nearby pattern.** Closest example ≠ matching preconditions — verify the new context shares the same constraints, base classes, scope, lifetime.
- **Holistic-first debugging — resist nearest-attention trap.** Don't dive into first plausible cause. List EVERY precondition (config, env vars, paths, DB, endpoints, creds, versions, DI, data). Verify each against evidence (grep/query — not reasoning). Ask "what would falsify this?" — if nothing, it's not a hypothesis. Most expensive failure: going deeper in "obvious" layer while bug sits in layer never questioned.
- **Surgical changes — apply the diff test (context-aware).** Two modes: (1) Bug fix → every line traces to the bug; no restyling; orphan cleanup only for imports YOUR changes made unused. (2) Review/enhancement → implement improvements AND announce as "Enhancement beyond main request: [what]". Never silently scope-creep. Diff test: "Would this line exist if I wasn't asked to do X?" — if no, delete or announce.
- **Surface ambiguity before coding — don't pick silently.** Multiple valid interpretations → present each with effort: "[Request] could mean (1) [N h], (2) [N h]. Which matters?" List scope/format/volume/constraints assumptions first. If simpler path exists, say so. Never silently pick.
- **[MANDATORY FIRST ACTION] ALWAYS activate a suitable skill or workflow BEFORE responding.** Match task against workflow catalog + skill list; invoke via skill invocation or `$start-workflow <workflowId>`. NEVER answer or write code before checking. Skip = protocol violation.
- **Why-Review adversarial mindset — apply when reviewing any plan, decision, or design.** Default SKEPTIC not VALIDATOR: steel-man a rejected alternative, invert each stated reason ("what does it sacrifice?"), stress-test top 2-3 assumptions, run pre-mortem ("ships, fails in 3 months — what breaks?"), surface 1-2 alternatives author missed. Section presence ≠ quality; quality = causal reasoning + concrete mitigations + evidence, not "it's better" or "monitor closely".
- **Front-load report-write in sub-agent prompts for large reviews.** Many-file sub-agents hit budget before final write — findings lost. Design prompts so: (1) report-write is first explicit deliverable, (2) append per-file/section (not batched), (3) scope bounded so reads don't exhaust budget. Truncated mid-sentence with no report file → spawn narrower scope, don't retry same prompt.
- **After context compaction, re-verify all prior phase outcomes before continuing.** Summaries describe intent, not environment state (git index, filesystem, processes). On resume, FIRST audit: git status, re-read modified files, verify filesystem. Every "completed" claim is an untested hypothesis until evidence confirms.
- **OOM/memory: check row count before row size.** Triage: (1) Unbounded query — no DB filter for trigger? Push filter to DB; eliminates OOM. (2) Large rows? Projection reduces proportionally. Row reduction > projection in ROI.
- **Assert the outcome your system OWNS, never the intermediate state your INFRASTRUCTURE owns.** When testing anything asynchronous (queue/broker delivery, retries, background jobs, caches, replication), assert the final business/entity state. NEVER assert the delivery bookkeeping — consume/send status, attempt counts, last-error, row existence or counts in a broker, scheduler, or outbox/inbox table. That bookkeeping lives in shared infrastructure that ANY co-running process (a peer worker, a second replica, a leftover local container) can write, usually under a deterministic shared key, so the assertion silently tests the developer's environment instead of the system: green when run alone, flaky the instant anything else shares that broker + database. Gate question for every assertion: "would this hold no matter WHICH process did the work?" — if no, assert the converged data state instead. Corollary: process-local fault injection and in-process telemetry cannot gate work any process may perform — use them as stress amplifiers (arm → bounded window → disarm → assert convergence), never as preconditions.
- **Keep domain concepts out of generic/shared/infrastructure layers.** Reusable layer (shared library, framework, infra module) must reference NO consumer-specific domain concept — tenant/customer/product IDs, business entities, feature rules. Leak compiles + runs → passes review silently while coupling the "reusable" layer to one consumer. Keep shared type domain-free; push domain fields/logic down into the consumer via subclass/composition. — why: a layer coupled to one consumer's domain is no longer reusable.
