Conciseness

The body is dense and prescriptive: tables for naming and the tracking plan, an anti-patterns list, and no padding. The main over-explanation is the "Frameworks uteis" section defining AARRR ("Acquisition → Activation → Retention → Revenue → Referral") and HEART ("Happiness, Engagement, Adoption, Retention, Task success"), concepts Claude already knows. This fits anchor 4 (efficient, minor instances that could be trimmed) rather than 5; it is clearly above anchor 3 because the rest assumes competence and wastes few tokens.

Actionability

Guidance is fully concrete for an instruction-only skill: a copy-paste-ready tracking plan template table ("| Evento | Dispara quando | Propriedades | Tipo | Owner |"), a good/bad naming table with reasons, exact naming rules ("object_action, passado, snake_case"), enum-valued properties, a funnel format, and explicit server-vs-client firing rules. Per the scoring notes, absence of code is not penalized when guidance is this actionable, matching anchor 5.

Workflow Clarity

There is an explicit validation checkpoint with a feedback loop ("confirmar que o evento aparece no debugger/live events... Se não aparecer, checar API key/env e disparar de novo") and a completion checklist ("Evidencia de Conclusao"), but the overall workflow (entradas → convencao → tracking plan → metricas) is implied by section order rather than presented as an explicit sequence. That fits anchor 4 (clear sequence, most checkpoints, minor gaps) rather than 5, which expects a fully explicit ordered workflow.

Progressive Disclosure

No bundle files exist, and the ~110-line body is well organized into clearly labeled sections with one-level-deep, clearly signaled references ("policies/handoffs.md", "templates/analytics-plan.md"). Minor gaps: the frameworks section could live in a reference file, and referenced paths like templates/analytics-plan.md are external rather than part of the bundle. This fits anchor 4 (good structure, references mostly clear, minor organization gaps) rather than 5.

Specificity

"Define eventos, metricas e analises de produto" names the domain and a couple of actions (define events, metrics) but does not list the several specific capabilities the skill actually covers (tracking plan creation, naming convention, funnel mapping, instrumentation auditing). It matches anchor 3: domain plus 1-2 concrete actions, not comprehensive; it is above anchor 2 because actions are named, but below anchor 4 because no list of several specific actions appears.

Completeness

It explicitly answers both: what ("Define eventos, metricas e analises de produto") and when ("Trigger em: ..." followed by concrete trigger phrases), which is an explicit 'Use when'-equivalent clause. This matches anchor 5 (clear what AND when with concrete trigger phrases); it is not anchor 4 because the when-clause is explicit and phrase-level, not merely implied or generic.

Trigger Term Quality

The trigger list covers natural terms comprehensively with synonyms and product names: "tracking", "analytics", "eventos de produto", "funil de conversao", "instrumentar evento", "tracking plan", "data analytics", "PostHog", "Amplitude", "Mixpanel". This matches the anchor-5 pattern of comprehensive natural-term coverage including synonyms and tool names; anchor 4 would require notable missing terms, which is not the case.

Distinctiveness Conflict Risk

The niche is clear and mostly distinct thanks to specific triggers like "tracking plan", "instrumentar evento", "ativacao" and the tool names PostHog/Amplitude/Mixpanel. However, the generic terms "analytics" and "data analytics" could overlap with general data-analysis or BI skills, so it fits anchor 4 (mostly distinct, minor overlap risk) rather than anchor 5 (minimal conflict risk).
