Conciseness

The body is dense and purposeful — comparison tables, a numbered async flow, and delegation of detail to patterns/ and policies/ files — with almost no explanation of concepts Claude already knows. It is not a 5 because there is mild redundancy: the sync-is-a-bug point appears in the comparison table, the 'Por isso o fluxo NUNCA e sincrono' line, and again in 'Anti-padroes frequentes'.

Actionability

For an instruction-only skill the guidance is concrete: a 7-step reference flow, specific decisions ('mova o asset pro seu storage', 'dedupe por job_id', 'TTL + estado failed'), a default provider recommendation ('rotear via FAL.ai'), and a copy-paste-ready cinematographic prompt example. It is not a 5 because no executable code or commands appear and implementation detail is delegated to external patterns/ files rather than shown, leaving minor gaps.

Workflow Clarity

The async flow is clearly sequenced (steps 1-7 with a 5a/5b webhook/poll branch) and includes an explicit validation checkpoint with a feedback loop: 'Checkpoint antes de liberar: simular os 3 caminhos de falha... Corrigir o caminho que falhar e repetir a simulacao antes de liberar'. Cost confirmation (step 2) guards the expensive batch-like operation, matching the anchor-5 pattern of sequence plus explicit validation and retry loop.

Progressive Disclosure

The SKILL.md is a well-organized overview with a single clearly signaled, one-level-deep bundle reference — 'ver `references/vocabulario-cinematografico.md`' — which exists in the bundle and states when to load it, while deep implementation detail is delegated to kit patterns/ and policies/ files rather than inlined. This matches the anchor of a clear overview with well-signaled one-level-deep references and appropriate content split.

Specificity

The description enumerates several concrete capabilities — "text-to-video, image-to-video, clips promocionais, avatar video, motion explainers" — which matches the anchor 'lists several specific actions; minor gaps in coverage'. It is not a 5 because the governing verbs remain generic ('integrar geracao e manipulacao de video') and 'manipulacao' is unspecified; not a 3 because far more than 1-2 concrete capabilities are named.

Completeness

It explicitly answers both what ('Skill para integrar geracao e manipulacao de video em aplicacoes') and when ('Use quando o app precisar de...') with concrete trigger phrases appended, which is exactly the anchor-5 pattern. A 4 would require the 'when' to be less explicit, but here it is stated twice (Use-quando clause plus a dedicated trigger list).

Trigger Term Quality

The trigger list is comprehensive and natural in both Portuguese and English — "gerar video", "video generativo", "clip promocional", "text-to-video", "fal video", "Sora", "Veo", "Runway video", "video AI" — including provider names and synonyms users would actually say. Only trivial variations (e.g. 't2v', 'generate video' in English) are absent, which keeps it at 5 rather than dropping to 4.

Distinctiveness Conflict Risk

The niche is clear with distinct triggers (Sora, Veo, fal video, avatar video), but 'manipulacao de video' is broad enough to risk overlap with a video-editing/ffmpeg skill since no exclusion boundary appears in the description itself. Mostly distinct with minor overlap risk matches anchor 4; anchor 5 would require the description alone to delimit the boundary.
