Conciseness

The ~80-line body is lean and assumes Claude's competence: it never explains what an ADR is or why decisions get recorded, gives a two-line framing then goes straight into a compact template, terse numbered workflows, and a short quality-standards list. Every section earns its place; nothing matches the over-explanation in the anchor-4 example.

Actionability

Fully executable throughout: a complete copy-paste markdown template with every mandatory section, the exact command `Glob docs/adr/[0-9]*.md`, the exact file-naming rule `docs/adr/NNNN-kebab-title.md`, a concrete index table format `| ADR | Title | Status | Date |`, and specific supersession semantics (update old Status, add back-reference). This matches the anchor-5 fully-executable standard.

Workflow Clarity

Both workflows are clearly sequenced, with an explicit checkpoint ("Present the draft — show it to the user for review before writing any file") and fallback branches ("If not, offer to start the ADR directory"; "If no ADR matches, suggest recording one now"). The gap keeping it below anchor 5: the recording workflow's step 7 ("Update the index") assumes docs/adr/README.md already exists and its table format is known, with no instruction for creating or verifying it — a minor validation gap characteristic of anchor 4. No destructive/batch cap applies since writes are additive new files.

Progressive Disclosure

No bundle files exist, and none are needed: all content (when-to-record, template, workflows, quality standards) is core operational material that correctly lives inline, organized under clear headers. There are no buried or nested references and no monolithic wall of content that should be split out, so a self-contained, well-sectioned file is the appropriate structure.

Specificity

Several concrete actions are named — "Record an architecture decision as an ADR in docs/adr/", choosing among "frameworks, libraries, databases, or architectural patterns", stating a decision with reasoning, and "querying past decisions" — with only minor gaps (no mention of listing, searching, or updating/superseding decisions). It sits above anchor 3 (only 1-2 actions) but short of anchor 5's fully comprehensive coverage.

Completeness

Both questions are explicitly and concretely answered: what it does ("Record an architecture decision as an ADR in docs/adr/") and when to use it ("Use when choosing between frameworks, libraries, databases, or architectural patterns; stating a decision with reasoning...; or querying past decisions"). This matches the anchor-5 example structure exactly and clearly exceeds anchor 4, where the 'when' clause is less specific.

Trigger Term Quality

Natural phrases users would actually say are quoted directly ("we decided X instead of Y because...", "why did we choose X?") along with concrete trigger domains (frameworks, libraries, databases, architectural patterns). It falls short of anchor 5's comprehensive synonym coverage — missing variations like "tech choice", "decision log", or "architecture decision record" spelled out beyond the single ADR acronym.

Distinctiveness Conflict Risk

The ADR framing carves a clear niche with distinct triggers ("we decided X instead of Y because..."), giving minimal conflict risk overall. However, "Use when choosing between frameworks, libraries, databases" could fire on general technology-comparison questions where the user wants advice rather than a recorded decision — a minor overlap with general advisory skills that keeps it below anchor 5.
