Conciseness

The guidance itself is tight and assumes competence (e.g., 'a JSDoc @param restating a parameter's type the signature already shows is noise'), but 'When to Apply', 'Use When', and 'In Scope' three times repeat the same four trigger scenarios in slightly different forms. Not 4: the triple duplication is more than 'minor over-explanation that could be trimmed'; not 2: nothing explains concepts Claude already knows, and the anti-patterns with BAD/GOOD examples earn their tokens.

Actionability

Concrete, executable guidance throughout: a copy-paste command ('npx typedoc --out docs src/index.ts'), complete BAD/GOOD JSDoc code examples, and a specific ADR structure (Context/Decision/Alternatives Considered/Consequences). Not 5: some common cases lack inline specifics — e.g., no minimal typedoc.json snippet or JSDoc example for a NestJS decorator, though these are deferred to the (real) reference files; not 3: what is inline is real code and commands, not pseudocode or hints.

Workflow Clarity

The JSDoc-first-then-TypeDoc ordering is only implied by an anti-pattern ('NEVER configure TypeDoc without first ensuring the source has real JSDoc'), and there is no explicit step sequence or validation checkpoint; the only verification note ('actually running npx typedoc and checking the generated output') lives in 'When NOT to Use' rather than a workflow. Not 4: no clearly listed sequence with checkpoints for the generate-and-publish flow; not 2: the anti-patterns do convey a coherent implicit order and the 'When NOT to Use' section covers misuse.

Progressive Disclosure

Clear overview structure with a References table mapping each of the four topics to a real one-level-deep file (all four exist in references/), each with a 'Covers' description, plus curated external links. Content is appropriately split: principles and anti-patterns inline, bulk detail in the reference files. Matches the anchor-5 pattern exactly.

Specificity

The description lists multiple specific concrete capabilities — 'JSDoc comment patterns that surface in IDE tooltips, TypeDoc configuration for generating API documentation sites, Architectural Decision Record (ADR) templates... framework-specific documentation patterns (NestJS, React, Angular/Compodoc)' — comprehensively covering the skill's four domains. Not 4: coverage of the skill's scope is complete with no gaps; each capability is named concretely rather than generically.

Completeness

Explicitly answers both questions: 'what' via the four listed capability areas and 'when' via the concrete trigger clause 'Use when writing JSDoc for a public API, setting up TypeDoc to generate documentation from source, recording why a technical decision was made, or documenting a framework-specific pattern.' This matches the anchor-5 example pattern (what + 'Use when...' with concrete triggers) exactly.

Trigger Term Quality

Strong natural keyword coverage — 'JSDoc', 'TypeDoc', 'ADR', 'NestJS', 'React', 'Angular/Compodoc', 'public API', 'API documentation sites' — terms users would actually say. Not 5: a few natural synonyms are missing (e.g., 'doc comments', 'API docs', 'documentation site' as a bare phrase); not 3: far more than partial keyword coverage since every major trigger term a user would utter is present.

Distinctiveness Conflict Risk

Clear niche (TypeScript documentation tooling) with distinct triggers (JSDoc, TypeDoc, ADR, framework docs) — a user asking to 'write JSDoc' or 'set up TypeDoc' would unambiguously land here rather than on a general TypeScript-practices skill. Not 4: no meaningful overlap risk with sibling TypeScript skills since the description scopes strictly to documentation of code, not type design or practices.
