Conciseness

The body is a lean, instruction-only playbook with no padding or explanation of concepts Claude already knows (e.g. the bytes-vs-tokens distinction is stated operationally, not pedagogically). However, the disk-versus-loaded distinction is repeated across the Fase 1 bullets, the four-layer numbered list, and Fase 3, which could be consolidated — fitting anchor 4 (minor over-explanation that could be trimmed) rather than anchor 5.

Actionability

Concrete executable guidance is present throughout: "node scripts/skill-catalog-budget.mjs", "--observed <arquivo>", the chars ÷ 4 proxy, alert thresholds at 80%/95%, and invocation examples ("Skill({ skill: \"dev-team-kit-fv:49-context-budget\" })", "/context-budget"). Minor gaps — no example of the captured hook JSON or a sample Fase 3 report format — keep it at anchor 4 rather than fully copy-paste-ready anchor 5.

Workflow Clarity

The Fase 0→4 sequence is clearly ordered with explicit guardrails and checkpoints: "Não execute --apply durante uma auditoria", approval required before disabling MCP, and alerts computed only against a "janela medida". It lacks explicit validate→fix→retry feedback loops, so it fits anchor 4 (clear sequence, most checkpoints) rather than anchor 5.

Progressive Disclosure

The ~90-line single-purpose playbook is appropriately self-contained with well-organized sections (Objetivo, Quando usar, Protocolo, Integração, Exemplo) and one-level-deep, clearly signaled references to kit scripts ("scripts/skill-catalog-budget.mjs", "scripts/skill-health.mjs"). Nothing belongs in a separate file and there are no nested references, matching the well-organized-structure standard for a skill of this scope.

Specificity

"Mede e reduz o peso de contexto carregado pelo agente" names the domain and exactly two concrete actions (measure, reduce) without enumerating the audited components (root instructions, rules, skills, MCP descriptions). This matches anchor 3 (1-2 concrete actions, not comprehensive), not anchor 4 which requires several specific listed actions.

Completeness

It clearly answers "what" in third person ("Mede e reduz o peso de contexto carregado pelo agente") and "when" via an explicit "Trigger em:" clause with concrete trigger phrases, exactly matching anchor 5. Anchor 4 would require the when-clause to be less explicit, which is not the case.

Trigger Term Quality

The explicit "Trigger em:" list provides twelve natural phrases with good PT/EN synonym coverage ("contexto inchado", "context overflow", "context budget", "tokens carregados"). A few plausible natural phrasings are still missing (e.g. "janela de contexto", "prompt grande"), so it fits anchor 4 rather than comprehensive anchor 5.

Distinctiveness Conflict Risk

The loaded-context overhead niche is distinct with mostly specific triggers ("overhead de rules", "impacto do MCP no contexto"), but broad triggers like "sessao lenta" and "respostas degradadas" create minor overlap risk with performance or cost-tracking skills. Fits anchor 4 (mostly distinct, minor overlap) rather than anchor 5 (minimal conflict risk).
