Conciseness

The body is lean and assumes competence — no re-teaching of known concepts, terse section-based rules like "no maximo 15 tarefas ativas". Minor over-explanation remains: "Evidencia de Conclusao" largely restates earlier sections, and the mem9 GitHub attribution explains provenance rather than instructing. Not 5 due to these trimmable passages; well above the noticeably-verbose 2 and the mostly-efficient-but-padded 3.

Actionability

Mostly concrete: the lifecycle string "Criar item (pending) -> Atualizar para in_progress -> Execucao -> Atualizar para completed -> Revisar lista geral", specific file paths (docs/context/current-focus.md, docs/context/history.md), hard limits, and a copy-paste YAML frontmatter snippet for utility sub-skills. Gaps remain — directives like "identificar se o novo pedido compete com o trabalho ativo" are abstract, and key operational detail is deferred to policy files not present in the bundle. Not 5 because a significant share of guidance describes rather than instructs.

Workflow Clarity

The task lifecycle has a clear sequence plus an explicit validation checkpoint with error recovery ("Se a verificacao falhar, a tarefa volta pra in_progress com a razao anotada"), a genuine feedback loop. However, the focus-change workflow has no checkpoints, "Execucao" is an abstract step, and validation detail is deferred to an absent policies/verification-before-completion.md. Matches "clear sequence with most checkpoints present; minor validation gaps" rather than the fully-explicit 5 anchor.

Progressive Disclosure

The body itself is well-sectioned and keeps references one level deep and clearly named, but every referenced file — GLOBAL.md, policies/execution.md, policies/persistence.md, policies/token-efficiency.md, policies/handoffs.md, policies/evals.md, policies/verification-before-completion.md, templates/handoff.md — is absent from the bundle (no references/ directory exists), so navigation dead-ends. Structure is better than the minimal anchor (2) but the dangling, unbundleable references keep it below "most content is appropriately placed" (4).

Specificity

Lists several distinct concrete actions — "organizar tarefas, acompanhar progresso, trocar foco de trabalho, ou manter historico resumido" plus "persistencia enxuta entre sessoes" — with only minor gaps (the underlying mechanism is named generically as "mecanismo de task, memoria ou checklist"). Not 5 because coverage of the actions is not fully comprehensive; not 3 because it goes well beyond 1-2 actions.

Completeness

Explicitly answers both what ("Skill de gerenciamento de contexto e tarefas usando o mecanismo de task, memoria ou checklist... com persistencia enxuta entre sessoes") and when ("Use quando precisar organizar tarefas..." plus a concrete trigger-phrase list). Clearly matches the top anchor with concrete trigger phrases.

Trigger Term Quality

Provides an explicit trigger list of ten natural user phrases ("criar tarefa", "lista de tarefas", "status", "progresso", "trocar foco", "resetar contexto", "o que falta", "proxima tarefa", "historico", "pipeline de tarefas") in addition to a "Use quando" clause — comprehensive coverage of natural phrasings a user would actually say.

Distinctiveness Conflict Risk

The skill occupies a clear task/context-management niche and most triggers ("criar tarefa", "pipeline de tarefas", "trocar foco") are distinct, but single generic words like "status", "progresso" and "historico" could fire for other progress- or history-oriented skills. Mostly distinct with minor overlap risk, not the clean niche of the 5 anchor.
