The body is dense and operational with no padding explaining what FFmpeg/Playwright/perspective-compositing are, assuming Claude's competence; the few repeated mentions of the shadow-multiply trick reinforce distinct failure modes rather than restate the same point. Not a 2 because there is no unnecessary concept explanation or filler to trim.

Provides a copy-paste-ready bash workflow with real script paths and concrete parameters (0.72/0.13 crop, dsf 2, shadow_strength ~0.85, 13.05/1.0), plus specific failure-mode fixes. Not a 2 because the guidance is fully executable rather than pseudocode or abstract direction.

The 'Workflow (free assembly)' is a clear ordered command sequence with an explicit verify step ('watch the master — music-only, every poster legible, shadow falls across the art, end card holds') and a Failure Modes section giving error-recovery loops. Not a 2 because the batch/render operation includes both a verification checkpoint and recovery guidance, clearing the validation cap.

The body is a well-organized overview (Three layers, Inputs, Workflow, Rules, Failure Modes) with one-level-deep, clearly signaled references to verified bundle files (scripts/PIPELINE.md, scripts/config.example.json, scripts/scene.html). Not a 2 because content is appropriately split and navigation is explicit, not a monolithic wall of text.

Lists many concrete actions (render video from a config, hard-cut through ~10 named poster mockup types, perspective-composite into the detected frame quad, multiply leaf-shadow back, sequence via FFmpeg) in third-person voice. Not a 2 because the action set is comprehensive and specific, not just a domain plus a few actions.

Clearly states what the skill does and includes an explicit 'Use for the brand-identity-reveal format' trigger, answering both what and when. A weak 3: the trigger is explicit but narrow and self-referential rather than covering multiple natural user cues, which keeps it from being a strong example.

Trigger phrasing ('Use for the brand-identity-reveal format') and terms lean on an internal format name plus capability identifiers (create-image-fal, create-music-elevenlabs) rather than the natural variations a user would say. Not a 3 because common natural keywords ('brand reveal video', 'product mockup reel') are absent; not a 1 because 'brand identity reveal', 'poster mockups', 'video' are relevant.

The hard-cut poster-mockup-in-a-real-lit-space format with FFmpeg/Playwright composite is a distinct niche unlikely to trigger for unrelated skills. Not a 2 because the format signature is highly specific rather than a broad 'works with videos' overlap.
