# ADR — Architecture Decisions (WHAT)

**Template:** `references/default-template.md` — local reference for ADR structure and workflow.

## Default guardrails (before any final content)

1. Apply **`output-handshake`**: confirm **where** the final ADR will be recorded and that a **human** will review.
2. Then follow the steps below.

## When to use

Use **`decision-log`** for lightweight product/project/operational decisions and **`agreement`** for explicit commitments or terms among parties. Use this ADR skill only for durable architecture or technical decisions.

- A change has **long-term** architectural, security, data-model, or cost impact.
- You need **options with pros/cons** and a **record** for future readers (and for supersession later).
- The project needs decisions linked to PRDs, TRDs, tasks, PRs, diagrams, or other supporting artifacts.

## Instructions

0. **Match existing convention first** (per `addyosmani/agent-skills` `documentation-and-adrs` 2026-08-12, diff `docs/research/diff-394-documentation-and-adrs.md`): inspect `docs/adrs/` (or `Documentation/Decisions/`, MADR, `adr-tools` `.adr-dir`) — location/format (Markdown vs reStructuredText), numbering/naming (`ADR-004-*.md` vs `0004-*.md`), section headings. Surface conflict rather than silently introducing another scheme. Only when no convention can be established, default to `docs/adrs/000N-*.md` or `docs/adrs/ADR-0xx-*.md` six-part structure.

1. **Confirm the decision qualifies** (new service, tech selection, schema change, deployment change, etc.) per the "When to Create an ADR" criteria.
2. **Draft** using the six-part structure: Title & status, Context, Options, Decision, Consequences, References (link **PRD/TRD**, tasks, PRs, diagrams as applicable). Use lifecycle `PROPOSED → ACCEPTED → (SUPERSEDED | DEPRECATED)` and **don't delete old ADRs** — when decision changes, write new ADR that references and supersedes old (per upstream 2026-08-12).
3. **Review** with the tech lead / peers as in the workflow; keep ADRs **short and actionable** (clarity over completeness).
4. **Link** the ADR to the relevant **epic or story** and to **PRs** in the forge (use **`github-cli-workflow` / `gitlab-cli-workflow`** for PR text when applicable).
5. If an ADR is **superseded**, **preserve history**: update status and point to the replacement document.

### Red flags & verification (after documenting)

* **No ADR for significant architectural choices** — every expensive-to-reverse decision needs one.
* **README missing quick start / architecture overview**, API without types, rules files (`CLAUDE.md`/`AGENTS.md`) stale, commented-out code, week-old `TODO`s, or docs that restate code.
* Verify: ADRs exist, README covers quick start/commands/architecture (link ADRs), API docs have types, gotchas inline, no commented-out code, `personas/` (HOW agent thinks) vs `skills/` (HOW task executes) preserved — see `docs/CONCEPTS.md`.

## What not to do

- Do not use an ADR for one-line fixes with no long-term effect (use a normal task or PR description).
- Do not paste the full org policy into this skill; keep a single **canonical** copy in the wiki.
