Names the domain (repository auditing) and lists several areas it covers (stack, conventions, assets, tests, docs, risks, integration points), but the actions are somewhat vague — 'mapear' (map) is the only concrete verb, and the outputs are described generically as 'markdown reutilizavel'.

Clearly answers both 'what' (audit repository to map stack, conventions, assets, tests, docs, risks, integration points and persist results in reusable markdown) and 'when' (explicitly states 'Use quando precisar mapear stack real... antes de executar outras skills'). The 'Use quando' clause is explicit and well-defined.

Includes some relevant terms like 'auditoria', 'repositorio', 'stack', 'testes', 'docs', 'riscos', 'integracao', but these are mostly domain-specific Portuguese terms. Missing common natural user phrases like 'analyze repo', 'codebase overview', 'project structure', or 'onboarding'. The language barrier may also reduce trigger matching for English-speaking users.

The description carves out a clear niche as an initial/continuous repository audit skill that runs before other skills. The combination of auditing scope (stack, conventions, risks, integration points) and the explicit positioning as a prerequisite step makes it highly distinctive and unlikely to conflict with other skills.

The skill is reasonably structured but includes some redundant sections (e.g., 'Quando Usar' vs 'Quando Reauditar' overlap, 'Entradas Esperadas' is vague and adds little value, 'Responsabilidades' largely restates what's already covered elsewhere). The split catalog and detection rules are efficient, but overall the document could be tightened by ~30%.

The split catalog with detection heuristics (e.g., check for 'schema.prisma', 'Dockerfile', etc.) provides concrete guidance, and the output file paths are specific. However, there are no executable code examples, no concrete commands for running the audit, and the 'Conteudo Minimo' section is a checklist of topics rather than actionable steps with specific formats or templates shown inline.

The skill describes what to produce and when to trigger, but lacks a clear sequential workflow with numbered steps for actually performing the audit. There are no validation checkpoints (e.g., verify the audit is complete, validate split file sizes, confirm git diff before incremental update). The process is implied rather than explicitly sequenced.

The skill effectively uses progressive disclosure: it references `docs/skill-guides/repo-auditor.md` for deeper guidance, points to `templates/audit.md` for structure, and references multiple policy files. The split catalog itself is a form of progressive disclosure for output. References are one level deep and clearly signaled.
