Conciseness

The body is overwhelmingly example-driven (ADR template, good/bad comment pairs, TSDoc, OpenAPI, verification checklist) rather than explaining concepts Claude already knows. Not 5 because the README structure and changelog templates restate formats Claude already knows, and the "Common Rationalizations" table is motivational padding that could be trimmed.

Actionability

Fully copy-paste-ready guidance throughout: a complete worked ADR template with alternatives and consequences, executable TypeScript comment examples with explicit BAD/GOOD contrasts, a full TSDoc example, an OpenAPI snippet, and a terminal verification checklist. Specific examples cover the common documentation cases.

Workflow Clarity

The primary workflow is clearly sequenced: inspect for existing convention first (location, numbering, headings), match it, surface conflicts explicitly, and only then apply the default template — plus a closing Verification checklist as checkpoints. Not 5 because there is no explicit error-recovery/feedback loop; not 3 because checkpoints are present and explicit rather than implicit.

Progressive Disclosure

Well-organized single file with clear section headers and no nested or buried references (there are no bundle files at all). Not 5 because at ~280 lines the README, changelog, and API-documentation example blocks are candidates for reference files to slim the main file, and the under-50-line simple-skill exception does not apply. Not 3 because nothing is buried and structure is consistently good.

Specificity

"Records decisions and documentation" names the domain with a single generic action verb; the concrete specifics (ADR, design choice, public APIs) appear only in the when-clause, so the what-side lists 1-2 actions without comprehensive coverage. Not 4 because the description's capability statement itself offers no specific concrete actions like the anchor-4 example.

Completeness

Both what and when are present, and the "Use when..." clause is explicit with multiple concrete triggers (5-level when). Not 5 because the what-side — "Records decisions and documentation" — is a single vague action, far short of the anchor-5 example's list of concrete capabilities. Not 3 because both halves are clearly and explicitly present.

Trigger Term Quality

Natural phrases users would say are present — "document an architecture decision (ADR)", "the reasoning behind a design choice", "changing public APIs", "shipping features". Not 5 because common natural terms the skill actually covers — README, changelog, code comments, CLAUDE.md/rules files — are missing from the description, so those user requests would not trigger it.

Distinctiveness Conflict Risk

The ADR/design-rationale niche has distinct triggers, but "shipping features" and "record context that future engineers... need to understand the codebase" are broad and could overlap with changelog, commit-message, or README-type skills. Not 5 due to this residual overlap; not 3 because the primary triggers are clearly specific to decision documentation.
