Conciseness

The body is dense and operational with no concept-explainer padding, but the exit-4/invalid-usage detection criteria are stated twice nearly verbatim ("`4` erro de configuração ou ferramenta ausente" followed by "O `4` é erro de configuração ou ferramenta ausente...", and the "stderr começa com `usage: bob`... Não é o exit `2`" clause repeated in step 1). This matches 'mostly efficient but includes some unnecessary explanation or could be tightened' rather than level 2, since the redundancy is localized and the rest earns its tokens.

Actionability

The skill provides a copy-paste-ready PR body template, exact commands (`bob check --format both`), concrete exit-code meanings, file paths, and explicit per-section placement rules, fully covering the common case. It matches 'fully executable; copy-paste ready code or commands'.

Workflow Clarity

Four clearly sequenced steps, each with an explicit 'Feito quando...' completion checkpoint, plus an error-recovery branch (exit-4 invalid usage detected via stderr heuristics redirects to the `bob-check` skill and forbids re-running the same argv). This matches the top anchor: clear sequence, explicit validation, feedback loop for error recovery.

Progressive Disclosure

The single-file skill is well-sectioned (Quando, Interface da CLI, Passos, Formato do relatório, Molde do corpo do PR) with clearly signaled external references ("Fonte do formato: `docs/SPEC.md`", "Catálogo em `docs/exit-codes.md#exit-4`"). It is not level 5 because the inline exit-code catalog partially duplicates the referenced `docs/exit-codes.md`, and stray floating lines ("⏭️ permanece ⏭️, com o motivo") sit outside any section.

Specificity

"Resumir `.bob/report.md` no corpo do PR" names the domain and one concrete action with a specific file and destination, matching the 'names domain and 1-2 concrete actions' anchor. It does not list several specific actions, so it falls short of level 4, while the single action is far too concrete for level 2.

Completeness

It explicitly answers what ("Resumir `.bob/report.md` no corpo do PR") and when ("Use ao escrever ou atualizar um pull request depois de `bob check`") with concrete trigger phrases, matching the top anchor. The 'when' clause is already specific and conditional, so level 4's 'could be more explicit' does not apply.

Trigger Term Quality

Natural trigger phrases like "pull request", "PR", "escrever ou atualizar" are present and map well to what a user would say. Common synonyms (e.g., "abrir/criar pull request", "descrição do PR") are missing, keeping it just below the comprehensive level 5.

Distinctiveness Conflict Risk

Triggers are anchored to tool-specific artifacts (`.bob/report.md`, `bob check`, PR body), giving the skill a clear niche with minimal overlap risk against generic PR-writing or review skills.
