Claude Skills by Uxcel-Lab

Run a structured rigor audit on how a team validated (or plans to validate) its assumptions — for a discovery plan, experiment, test, or any "we validated it" claim. Produces a severity-rated issue list with concrete fixes — catches testing the comfortable assumption instead of the riskiest, untestable phrasing, method fidelity mismatched to decision risk, stated intent mistaken for behavior, success criteria set after the fact, goalpost-moving, and underpowered evidence. Use when reviewing a...

Run a structured quality audit on a product decision or its rationale — a build/buy/sunset/re-platform/pricing call, a decision log, a retrospective, or any "we decided X because…". Produces a severity-rated issue list with concrete fixes — catches outcome-based reasoning (resulting), deliberation mismatched to reversibility, uncalibrated confidence, confirmation/anchoring/framing/sunk-cost bias, missing pre-mortems, and undocumented reasoning. Use when reviewing a major decision or its write...

Run a structured validity audit on OKRs, KPIs, North Star Metrics, or any success-metric set. Produces a severity-rated issue list with concrete fixes — catches vanity metrics, unfalsifiable key results, outputs disguised as outcomes, gameable targets without guardrails, and metrics disconnected from business value. Use when reviewing OKRs, goals, KPIs, dashboards, or success metrics, or as a validation step after defining metrics in a spec, roadmap, or strategy doc.

Run a structured rigor audit on prioritization decisions, scored backlogs, RICE/ICE/MoSCoW outputs, or roadmap orderings. Produces a severity-rated issue list with concrete fixes — catches invented scores with false precision, priorities unmoored from strategy, feature-factory ordering, everything-is-a-must-have inflation, and trade-offs left implicit. Use when reviewing a prioritized backlog, scoring exercise, roadmap order, or "what should we build first" decision, or as a validation step a...

Run a structured quality audit on a product spec, PRD, or requirements document. Produces a severity-rated issue list with concrete fixes — catches untestable requirements, happy-path-only flows, missing scope exclusions, absent dependencies/constraints/assumptions, implementation details leaking into functional specs, and unvalidated assumptions presented as facts. Use when reviewing a spec, PRD, or requirements doc, or as the validation step after writing one.

Produce or critique a competitive/market analysis that yields a strategic edge — not a flat feature table. Scopes to a research objective and industry context, finds direct/indirect/potential competitors, profiles them from honest public sources, applies the right framework (perceptual map, feature matrix, SWOT, Porter's, TAM/SAM/SOM), and ends with strategic implications and a positioning conclusion. Applies the always-true core and gates context-dependent decisions (which framework, primary...

Build a go-to-market plan that's a stage-appropriate system — customers, channels, pricing, timing, and partnerships that fit the company's maturity — not a generic launch checklist. Gates on GTM readiness (validated demand) and company stage, picks the right channel and entry timing, and treats the buyer journey as non-linear. Catches the defaults Claude misses: GTM-as-one-time-launch, stage-skipping, channel/timing blindness, funnel-forcing, partnerships-as-shortcut. Trigger when asked to c...

Write OKRs, KPIs, or a North Star Metric derived from product strategy — or review an existing goal set. Enforces outcome-based key results with baselines and targets, one focus objective per team per cycle, leading+lagging balance, and guardrails against gameable targets. Trigger when asked to write OKRs, set quarterly goals, define KPIs or success metrics, choose a North Star Metric, or run goal-setting/planning for a team or product.

Write a product requirements document (PRD) or spec anchored to a validated problem, with measurable requirements and surfaced risks — or review an existing one. Trigger when asked to write a PRD, product spec, user stories, technical requirements, or to review/critique an existing spec document.

Create or critique a product roadmap — outcome-oriented, theme-based, confidence-aware (Now-Next-Later) roadmaps tied to strategy, instead of dated feature lists. Gates format and detail by audience and planning horizon. Trigger when the user asks to build, write, review, or restructure a product roadmap, quarterly/annual plan, Now-Next-Later view, or roadmap presentation.

Produce or critique a product vision and/or product strategy — an aspirational destination and the deliberate, trade-off-driven choices to reach it — not a buzzword poster or a feature list. Distinguishes the vision/strategy/roadmap/mission artifacts, ladders product vision up to company vision, forces a focused segment + differentiation + explicit "won't do", and sets the stability rule (stubborn on vision, flexible on strategy). Applies the always-true core and gates context-dependent decis...

Build or critique an audience-understanding artifact — research-based user personas, a Jobs-to-Be-Done framing, or the choice between them. Grounds the work in real research (never invented demographic fiction), keeps only detail that changes a decision, and picks the lens by research objective, stage, and resources. Applies the always-true core and gates context-dependent decisions (personas vs. JTBD vs. both, research-based vs. proto, how many personas, which details, segmentation depth, AI...

Write or critique a product problem statement — turning a vague prompt, signal, or feature request into a clear, evidence-grounded, testable statement of the real problem before any solution. Separates the problem from solutions, symptoms, goals, and constraints; applies the always-true core (gap not feature, root cause not symptom, specific and measurable, grounded in evidence, bridges user and business) and gates context-dependent decisions (which definition tool, how much measurability, re...

Write or critique a user story — a small unit of user value framed from a real persona's need, not a restated task. Frames stories around who/what/why, keeps them INVEST and testable, maps them across the journey, and resists writing stories that add no clarity. Applies the always-true core and gates context-dependent decisions (strict formula vs. free-form, whether to write a story at all, acceptance-criteria depth, splitting into a map, communication framing). Trigger when asked to write us...

Run a product-analytics analysis that produces a decision, not a dashboard — start from the question, pick actionable over vanity metrics, separate signal from noise, segment (averages lie), pair quant with qual, and end in an insight→impact→action story. Catches the defaults Claude misses: vanity metrics, correlation-as-causation, reacting to small samples/short windows, survivorship/selection bias, unsegmented averages. Trigger when asked to analyze product data/metrics, plan what to measur...

Plan how to test the assumptions behind a product idea before building — decompose the idea into its load-bearing beliefs, prioritize the riskiest, phrase them as falsifiable hypotheses, and pick the cheapest method that answers the question. Or critique an existing validation plan. Trigger when asked to validate an idea, de-risk a feature, plan discovery/experiments, test assumptions or a hypothesis, design an MVP test, or decide "how do we know this will work?"

Plan or critique a product discovery process — figuring out what to build before building it. Establishes which risk you're de-risking and how much certainty the decision needs, applies the always-true core (continuous not phased, outcomes over output, problem before solution, ask about past behavior, match evidence to risk, generate solutions from validated problems, research ethically) and gates the context-dependent decisions (problem vs. solution research, qual vs. quant, lightweight vs. ...

Design or critique an A/B test or controlled product experiment with statistical rigor — pre-registered falsifiable hypothesis, sample-size/power up front, a full business cycle, one primary metric plus guardrails, segment + long-term reads, and a pre-set iterate/pivot/persevere decision. Catches the defaults Claude misses: peeking/early stopping, tiny samples, no guardrails, vanity metrics, \"it won\" with no learning loop. Trigger when asked to set up or review an A/B test, design an experi...

Decide what to build first, or critique a prioritization. Derives criteria from strategy, picks the right framework for the context (RICE/ICE/MoSCoW/Kano/Impact-Effort), scores to expose trade-offs rather than manufacture false precision, sequences for flow, and says no with strategic context. Applies the always-true core and gates context-dependent decisions (which framework, scoring rigor, roadmap horizon, appetite vs. estimate, bets vs. tactical) with trade-offs. Trigger when asked to prio...

Orchestrated, idea-to-plan PM workflow. Establishes context once, then composes the PM generative ladder in order — problem → discovery → users → riskiest-assumption test → prioritization → spec → metrics — gating each step, enforcing evidence before the spec, and handing the result to product-review. Trigger when the user wants to go from a raw idea to a build-ready plan ("take me from problem to plan", "I have an app idea, where do I start", "turn this idea into a product plan", "plan a new...

Orchestrated review of a PM artifact (spec, PRD, OKRs, roadmap, prioritization, strategy). Routes by artifact type to the right audits, auto-runs the always-relevant assumption check, and returns one prioritized report. Trigger when the user asks for a full review of a PM document, "review my spec/roadmap/OKRs", "is this PRD solid", or general PM feedback — but NOT when they name a single specific audit.

Run a structured WCAG 2.1 AA accessibility audit on a design, screen, component, or page. Produces a prioritized issue list — each finding cites the violated WCAG criterion, a severity rating (Critical/Major/Minor), and a concrete fix. Use when auditing for a11y compliance or as a validation step after generating UI.

Audit the visual quality of a UI against established visual-design principles — hierarchy, emphasis, contrast, spacing, alignment, grouping, consistency, and depth. Produces a severity-rated issue list with concrete fixes. Specializes in catching overdesign, clutter, and competing focal points. Use when reviewing whether a screen looks professional, or as a validation step after generating UI.

Audit a UI, flow, or copy for dark (deceptive) patterns — design that manipulates users into unintended actions. Produces a prioritized findings list naming each pattern, its intent, severity, and an honest-design fix. Use when reviewing conversion flows, checkouts, paywalls, sign-ups, or cancellation flows for ethical design issues.

Run a structured usability audit of any UI against Nielsen's 10 heuristics. Produces a severity-rated, prioritized issue list — each finding tagged with the violated heuristic and a concrete fix. Use when auditing a screen, flow, or component for usability problems, or as a validation step after generating UI.

Run a structured information architecture audit on a sitemap, navigation tree, category structure, menu labels, or multi-screen product. Produces a severity-rated issue list with concrete fixes — catches scheme/task mismatches, narrow-and-deep hierarchies, low-information-scent labels, inconsistent labeling systems, single-path findability, and dead-end pages. Use when auditing IA, site structure, categories, taxonomy, or labels, or as a validation step after generating navigation or any mult...

Audit interface copy — labels, buttons, errors, empty states, tooltips, notifications, form hints — against UX-writing standards. Produces a severity-rated issue list with concrete rewrites. Use when reviewing UI copy for clarity, tone, and consistency, or as a validation step on any generated screen.

Run a structured mobile-responsiveness audit on a design, screen, or component — viewport adaptation and reflow, orientation, touch-target size and spacing, thumb reachability, mobile input ergonomics, gesture safety, and mobile readability/content priority. Produces a severity-rated issue list with concrete fixes. Use when reviewing whether a UI works on phones/tablets, or as a validation step after generating mobile or responsive UI.

Design or critique UI buttons — pick the right button type for the action's importance, apply sizing/label/state best practices, and gate stylistic levers like shape, shadows, FABs, and icon-only buttons. Trigger when the user asks to design, choose, style, or review buttons, CTAs, button labels, button hierarchy, or button states.

Design or critique UI cards — one-topic, scannable cards with clear hierarchy, the right container style (elevated, outlined, flat), and restrained shadows. Trigger when the user asks to design or review cards, card layouts, card grids, content tiles, user/profile cards, or a browse view built from cards.

Design or critique forms and input fields — field selection, labels, layout, validation, error states, and submission. Applies the always-true core (minimal fields, one column, labels outside inputs, inline validation) and gates levers like multi-step splitting, floating labels, and smart defaults. Trigger when the user asks to design, build, or review a form, signup/checkout/survey fields, input validation, or error messages.

Design or critique loading states and progress indicators — match the feedback type (spinner, text, determinate bar, skeleton, progress tracker) to the wait duration and task structure, and manage perceived performance. Trigger when the user asks to design or review loaders, spinners, loading states, skeleton screens, progress bars, progress trackers, steppers, or multi-step flow progress.

Design or critique UI menus — pick the right menu type (dropdown, cascading, contextual, single/multi-select, search, inline) for the action set, and apply item ordering, grouping, labeling, and state best practices. Trigger when the user asks to design or review a menu, dropdown, context/right-click menu, overflow (⋮) menu, or asks how to organize actions into a menu.

Design or critique modals, dialogs, alerts, popovers, and bottom sheets — gate WHEN interrupting users is justified, then apply dismissal, title/button, and focus best practices. Trigger when the user asks to design or review a modal, dialog, popup, overlay, confirmation, alert, permission request, lightbox, or bottom sheet — or asks whether something should be a modal at all.

Design or critique navigation systems — match the nav pattern (top bar, sidebar, tabs, hamburger, mega menu, bottom nav) to the information architecture, and apply wayfinding, header, breadcrumb, and pagination best practices. Trigger when the user asks to design or review navigation, menus, navbars, sidebars, tabs, breadcrumbs, headers, pagination, or asks "how should users move around" a site or app.

Design or critique notifications — pick the right type (badge, banner, snackbar, toast, alert, push) for the message's urgency, and respect user attention with timing, frequency, and opt-out controls. Trigger when the user asks to design or review notifications, toasts, snackbars, badges, banners, alerts, push notifications, or a notification strategy.

Design or critique search experiences — search input, auto-suggest, results page, filtering/sorting, and zero-results recovery. Matches search features to how users actually seek (known-item vs. exploratory) and gates levers like rich suggestions, filter layout, and chips. Trigger when the user asks to design or review search, a search bar, autocomplete/auto-suggest, search results, filters, sorting, or a "no results" page.

Design or critique selection controls — pick the right control (checkbox, radio button, toggle switch, dropdown, slider, picker) for the choice being made, and apply labeling, alignment, and state best practices. Trigger when the user asks to design or review checkboxes, radio buttons, toggles/switches, dropdowns, sliders, range filters, or any "which control should I use" question.

Design or critique data tables and lists — scannable structure, alignment rules (left for text, right for numbers), sorting/filtering, row interactions, and the right list type for the content. Trigger when the user asks to design or review a data table, data grid, admin table, list view, email/feed list, or asks how to present tabular or structured data.

Design or critique tooltips and contextual hints — decide when a tooltip clarifies vs. when it's a crutch for unclear design, and apply placement, styling, and brevity rules. Trigger when the user asks to design or review tooltips, hover hints, info icons, contextual help bubbles, or asks whether something needs a tooltip.

Design or critique a checkout, cart, payment, or booking flow — the path from "ready to buy" to "order confirmed." Applies the conversion-protecting core (guest checkout, transparent cost summary, inline validation, processing feedback, confirmation) and gates context-dependent levers (name fields, payment-method count, single- vs. multi-step, booking date pickers, promo-code prominence) with trade-offs. Trigger when designing or reviewing a checkout page, shopping cart, payment form, card-en...

Design or critique how a product prevents, surfaces, and recovers from errors — input/validation errors, system & network failures, AI/prediction failures, destructive actions, and 404/dead-end pages. Leads with prevention (most errors are designable away), applies the always-true core (validate without interrupting, write recoverable messages, give a safety net, never dead-end) and gates context-dependent levers (confirm vs. undo, validation timing, humor, degradation, transparency vs. secur...

Design or critique an offboarding flow — canceling a subscription, unsubscribing, or deleting an account. Leads with the ethical stance (leaving must be easy and respectful — hiding the exit is a dark pattern), applies the always-true core (findable exit, preserve goodwill, prevent accidental destruction, explain consequences, ask feedback respectfully, offer genuine alternatives, close with a recovery path) and gates the retention levers (incentive offers, value reminders, confirmation frict...

Design or critique a user-onboarding flow — the first-run experience that gets users to value fast. Gates context-dependent choices (onboarding method, progressive profiling, product tours) and applies the always-true core. Trigger when designing welcome screens, first-run experiences, product tours, activation flows, or when onboarding drop-off needs improving.

Design or critique a product's color palette and system — base hue, harmony, neutrals, semantic colors, tonal scales, and tokens. Applies the always-true core and gates context-dependent decisions (dark mode, brand expressiveness, accessibility trade-offs). Trigger when creating a color palette, choosing UI colors, building a color system, setting up color tokens, or reviewing a palette for issues.

Choose and design UI icons that are understood, not just decorative — universal metaphors, one consistent style, text/accessible labels where meaning isn't obvious, legible at small sizes, and adequate touch targets. Replaces ambiguous icon-only buttons and mixed icon styles with a system. Trigger when asked to add or pick icons, design an icon set, decide filled vs outlined, label icons, fix inconsistent/ambiguous iconography, or choose between a system library (SF Symbols/Material) and cust...

Lay out a screen with disciplined spacing, sizing, and grids — every value on one base unit (8px/4px scale), content aligned to a grid, proximity and whitespace doing the grouping, and space establishing visual hierarchy. Replaces arbitrary pixel values and ad-hoc alignment with a system. Also carries the spatial visual-hierarchy/alignment/composition fundamentals. Trigger when asked to design or critique a layout, set spacing/padding/margins, build a spacing scale or design tokens, choose or...

Write or improve UX microcopy — button labels, error and empty states, tooltips, form labels, notifications, and confirmations — so it's clear, concise, action-oriented, and on-voice. Trigger when asked to write microcopy, improve a button label or error message, write copy for a flow, or make interface copy clearer or friendlier.

Design or critique a product's typography — typeface selection and pairing, type scale, hierarchy, and readability settings (size, line length, line height, spacing, alignment). Trigger when choosing a typeface or font pairing, setting up a type scale, fixing typographic hierarchy, improving text readability, or reviewing a UI layout for typography issues.

Design or critique an activity feed / stream — a scannable list of updates where what matters stands out and noise fades. Gates the feed-type choice (chronological vs. algorithmic/ranked) and levers like notification aggregation, follow recommendations, and per-entry controls, while applying the always-true core (curated entries, legible text, relative timestamps, no empty feed, visible refresh status). Trigger when the user asks to design or review an activity feed, news/social feed, activit...
