Names the domain (documentation) and lists several types of documentation (features, APIs, arquitetura, setup, operação), but doesn't describe concrete actions beyond 'documentar' and 'manter atualizada'. Missing specific verbs like 'create', 'generate', 'update', 'review'.

Clearly answers both what (document features, APIs, architecture, setup, operation, maintain existing docs) and when (explicit 'Use quando' clause plus detailed 'Trigger em:' section with specific keywords).

Excellent coverage of natural trigger terms including both Portuguese and English variations: 'documentar', 'documentação', 'docs', 'ADR', 'README', 'feature doc', 'api doc', 'setup doc', 'runbook', 'troubleshooting'. These are terms users would naturally say.

Clear niche focused specifically on documentation with distinct triggers like 'ADR', 'runbook', 'troubleshooting', 'feature doc'. The specific documentation types and explicit trigger terms make it unlikely to conflict with general coding or other skills.

The skill is reasonably efficient but includes some redundant explanations (e.g., explaining what documentation is for, repeating 'nunca' rules). The governance section and multiple template references add overhead that could be consolidated.

Provides clear structure and categories but lacks concrete executable examples. No actual code snippets, curl commands, or copy-paste ready templates are included inline—everything references external files like 'documenter-templates.md'.

Clear temporal workflow ('Quando Documentar' section) with explicit phases: before coding, during design, during implementation, before deploy. The 4 levels are well-sequenced with clear 'Conteúdo obrigatório' checklists for each.

Excellent structure with clear overview and well-signaled one-level-deep references to templates and guides. Directory structure is explicit, and external references (documenter-templates.md, policies/) are clearly indicated without deep nesting.
