name	adr
description	Create a numbered ADR from the bundled template.
when_to_use	Use for any hard-to-reverse or cross-cutting choice (stack, database, auth, deployment, new pattern) or when asked to record a decision.

Write an ADR

Create a new Architecture Decision Record at /spec/decisions/000N-[slug].md in the product repo, from the bundled template.

Steps

1. Decide the next sequential number: list spec/decisions/ and use the highest existing 000N + 1 (start at 0001). Never renumber existing ADRs.
2. Pick a short kebab-case [slug] (use-postgres-for-search).
3. Ensure the dir exists (mkdir -p spec/decisions), then copy ${CLAUDE_PLUGIN_ROOT}/templates/spec/adr.md → spec/decisions/000N-[slug].md.
4. Fill in Context, Decision, Alternatives considered (with rejection reasons), and Consequences (positive / negative / neutral). Set Status to Proposed until accepted; set Deciders.

When to write one (and when not)

Write an ADR for choices that are hard to reverse (database, auth provider, deployment platform, tenancy model, major pattern), a new pattern other features will follow, an explicit rejection of an obvious alternative, or anything a future dev would ask "why did they do it this way?" about.

Do not write one for routine implementation choices, things obvious from the code, or single-feature decisions (those go in the feature's contract.md).

When superseding an ADR, mark the old one Superseded by [link] and link the new one — do not delete or renumber it. Full guidance: ${CLAUDE_PLUGIN_ROOT}/templates/reference/SPEC-FRAMEWORK.md.

ADRs are exempt from template reconciliation — they are immutable, point-in-time records. Never retrofit a newer adr.md template's sections into an existing ADR; supersede it with a new one instead.

Recommend the next action

After drafting the ADR, emit a ## Recommended next actions block per ${CLAUDE_PLUGIN_ROOT}/templates/reference/NEXT-ACTIONS.md. A freshly written ADR is Proposed, so the next step is a human decision — not a command.

Observed state	Category	Action / suggested command
ADR drafted, Status: Proposed	Human decision required	The Deciders ratify (Accepted) or reject it (no command)
ADR accepted, supersedes an older one	Recommended	Mark the old ADR Superseded by [link]
Accepted, no follow-up	Complete	No action is currently required.

The block recommends; ratifying the decision stays with the named Deciders.
