Conciseness

The body is dense and assumes competence — no basic video or Agent concepts are explained, and tables carry directive weight ('一拍一件事', '主体先动，镜头后动'). However, the 'promo is not a documentary' lesson is repeated four times (tips_exempt, §7, Failure-history brakes, Pressure test 6), which is trimmable over-explanation; not the level-5 'every token earns its place' anchor, but well above the level-3 'mostly efficient with unnecessary explanation' anchor.

Actionability

For an instruction-only skill the guidance is fully concrete: a fill-in sentence template ('Product-hero sentence: 这个产品让 [谁] 能 [发生什么变化]…'), a replacement test, a 7-beat causal story structure, named shot techniques (establish → focus → settle, match cut, J/L sound bridge), a columned cue-sheet table, a 5-row source-class table, and a concrete deliverable step ('复制 assets/director-brief-template.md, 至少填完…'). It meets the level-5 anchor with specific structures covering the common cases.

Workflow Clarity

The Intent Gate table sequences entry decisions; §1–§8 form a coherent pipeline (lock protagonist → pick format → visible actions → causal story → shots → sound → provenance → brief delivery → video-forge handoff) with explicit validation checkpoints: the replacement test, 9 pressure-test questions '交付 brief 前逐题回答', operator acceptance questions, and a staged cheap-to-expensive preview loop ('一句话、最危险那一段的最小样张、全片粗片…样张过之前只做那一段'). This matches the level-5 anchor: clear sequence, explicit validation, checklists, and feedback loops.

Progressive Disclosure

Structure within the body is good and the director-brief template is a real, clearly linked one-level asset, but the bundle has navigation gaps: assets/eli5-director-map.html (16KB) is never referenced from the body and is undiscoverable, and the three '../.cat-cafe-shared-refs/*.md' links (narrative-clarity, interaction-narrative, video-voice-and-timeline) do not resolve from this bundle. This fits the level-3 anchor (references present but not clearly signaled) better than level 4.

Specificity

The description lists multiple concrete actions with comprehensive coverage: '先锁产品主角、观众信念变化与影片格式，再把不可见的 Agent 协作翻译成可拍的故事、镜头、运动、声音和 provenance contract', plus '要拆参考片、写 creative brief/beat sheet', and a concrete Output list ('product-hero sentence + audience belief change + format decision + claim/proof beat sheet + shot/motion/sound maps + provenance ledger + operator acceptance questions'). Every claimed capability names a specific deliverable; not the level-4 anchor because there are no coverage gaps in the action list.

Completeness

Both 'what' and 'when' are explicit and concrete: the what is the creative-director-layer job plus a named Output list, and an explicit 'Use when:' clause gives concrete trigger phrases ('video-forge 开机前仍未锁定主语与镜头语法'). A 'Not for:' clause with redirect targets (video-forge, anime-forge, deep-research) further disambiguates the when.

Trigger Term Quality

Good natural trigger coverage: '用户问 Agent 产品宣传片如何导演/剪辑/叙事/配声音、要拆参考片、写 creative brief/beat sheet' — these are phrases a user would actually say. A few common synonyms are missing (e.g., '营销视频', 'product video', 'promo video' in English, '广告片'), so it does not reach the comprehensive-with-synonyms level-5 anchor.

Distinctiveness Conflict Risk

Clear niche — creative direction for Agent product promo films — with explicit boundaries against the adjacent skills: 'Not for: brief 已冻结后的录制/TTS/对齐/渲染（用 video-forge）、教程…（用 anime-forge）、只找时效性竞品（先用 deep-research）'. The GOTCHA line ('用户举的页面、thread 或成果只是候选证据，不自动成为影片主题') plus these redirects make wrong-skill triggering unlikely.
