The body is lean and structured (Goal/steps/Gate/Output per stage) and assumes Claude's competence without explaining concepts Claude already knows; tokens are largely purposeful.

Concrete structure and explicit output fields/classifications, but key details are missing — gates reference undefined thresholds ('coverage below threshold', 'too many unverifiable claims') and verification mechanics ('file_exists/line_exists/callable') without specifying how to perform them.

Eight clearly sequenced stages each with explicit validation gates and a defined failure loop (STOP → PRESERVE → report → AWAIT), giving strong checkpoints and feedback recovery.

Well-organized into clear sections, but it is a ~230-line monolithic single file with no bundle files and substantial inline detail (output schemas, failure-report template) that could be split into references.

Names the domain (codebase-feature documentation) and the core action (generating verified documentation with traceability), but the 'what' is essentially one capability with qualifiers rather than a list of multiple distinct concrete actions.

It explicitly answers both what ('Generates audit-grade, hallucination-free documentation from codebase features with full traceability') and when (an explicit 'Use when...' trigger clause).

The 'Use when documenting features, creating technical specs, or generating verified documentation with code references' clause uses natural phrasings a user would actually say, giving good trigger coverage.

The niche is distinct — verified, traceable documentation derived from codebase features with code references — making it unlikely to fire for generic writing or doc skills.
