Conciseness

The body is efficient and assumes Claude's competence — no basic concept explanations (ffmpeg, whisper, transcription) are present, and decision-relevant specifics like '~80 frames a 512px de largura ≈ 50-80k tokens de imagem' earn their tokens. Minor padding remains: 'Fontes Externas' credits and the 'Governança Global' file listing serve repo convention rather than task execution, keeping it below the lean 5 anchor.

Actionability

The only executable command is 'node scripts/setup-video-analysis.mjs' (plus '--check-only'); the core operations — yt-dlp download, ffmpeg frame extraction per strategy, faster-whisper invocation — are named but not shown, deferred to 'docs/skill-guides/video-analysis.md' which is not present in the bundle. Strategy parameters (caps of 50/100 frames, mono/16kHz preprocessing, GROQ_API_KEY/OPENAI_API_KEY fallback) are concrete, but the non-obvious executable details (e.g., the scene-aware scene-detection filter) are missing from what's provided, matching the 'concrete guidance but incomplete / missing key details' anchor rather than 'minor gaps'.

Workflow Clarity

'O Fluxo (3 passos, na ordem)' is a clearly sequenced conditional flow (subtitle first, frames only if visual question, transcription only without subtitle), and 'Checkpoint por passo: ler o resultado antes de avançar' adds explicit validation with feedback loops — bad auto-generated subtitle falls through to step 3, and a blurry/black frame loops back to step 1 with another download strategy. This matches the top anchor: clear sequence, explicit validation, error-recovery loops.

Progressive Disclosure

Good structure: lean sectioned overview with exactly one clearly signaled one-level-deep reference ('consultar docs/skill-guides/video-analysis.md apenas quando necessário') for the bulk command details. It falls short of a 5 because the referenced paths (scripts/setup-video-analysis.mjs, docs/skill-guides/video-analysis.md, GLOBAL.md, policies/*) are absent from the skill bundle, so the navigation they promise cannot be verified, and the transcription trade-off table plus anti-rationalization table sit inline where a reference file could carry them.

Specificity

It lists multiple specific concrete actions — 'baixar, extrair frames, transcrever audio e responder perguntas sobre o que acontece no video' — covering the skill's full scope (download, frame extraction, transcription, Q&A), matching the comprehensive multi-action 5 anchor. Not 4: there are no coverage gaps within its stated niche (existing-video analysis); not below: nothing is vague or abstract.

Completeness

It explicitly answers both: what — 'analisar conteudo de video existente: baixar, extrair frames, transcrever audio e responder perguntas' — and when — 'Use quando precisar entender, resumir ou buscar informacao dentro de um video ja existente', reinforced by the explicit 'Trigger em:' phrase list. This is the top-anchor pattern of concrete what + explicit when + concrete trigger phrases; the 'Use quando' clause is present so no cap applies.

Trigger Term Quality

The trigger list is comprehensive with synonyms in two languages — 'transcrever video'/'transcrever esse video', 'resumir video'/'resumir esse video', 'analisar video'/'analisar o conteudo desse video', 'extract frames from this video' — plus natural tool names users actually say ('whisper', 'yt-dlp', 'legenda automatica'). Matches the 5 anchor's comprehensive coverage including synonyms; only file extensions like .mp4 are absent, which is marginal given URL-based usage dominates this domain.

Distinctiveness Conflict Risk

It carves a clear niche — analysis of existing video — and explicitly fences off the nearest competing skill: 'nao para gerar video novo (isso e skill 27)'. Triggers ('transcrever video', 'extrair frames desse video', 'o que acontece nesse video') are phrased for this skill specifically, giving minimal conflict risk, matching the clear-niche 5 anchor.
