Conciseness

Mostly efficient — the beat spine, mapping table, and craft rules are load-bearing — but there is noticeable redundancy: 'the ONLY composited bitmap is the REAL product photo (objectFit:contain, never stretched)' and 'never AI-rendered text' each appear verbatim in the intro, the beats section, AND the Craft rules; 'never stretched' appears four times. The 'Choices' section also restates that decisions come from the recipe twice. Fits the 3 anchor ('could be tightened') better than 4, where redundancy would be only minor.

Actionability

Fully executable: the Run section gives copy-paste commands ('cd project && npm install', 'python3 scripts/render.py --config path/to/config.json --work-dir <work> --out <work>/master') with expected outputs named, the config→props mapping table tells exactly which key binds to which prop and scene, and a worked example config (scripts/config.example.json) is shipped. Gating checks state precise pass/fail vocabulary. Matches the 5 anchor; not 4 because no key execution detail is missing.

Workflow Clarity

Clear sequence with explicit validation checkpoints and feedback loops: two gating checks run pre-render and 'render.py rejects' on failure (validate→fix→retry), install is auto-run when node_modules is absent, and a post-render 'watch' QC checklist ('re-confirm both gating checks visually') closes the loop. This exceeds the 4 anchor, which allows minor validation gaps — none are present.

Progressive Disclosure

The body is well-sectioned and points to real bundle files (scripts/render.py, scripts/config.example.json — both verified present), but it repeatedly references a bundled 'project/' tree ('project/src/props.ts', 'project/src/lib/anim.ts', 'project/src/scenes/Scene01–04.tsx', 'project/package.json') that does not exist in the bundle, so those references are broken. Additionally, the 15-row config→props mapping table is inline reference material that belongs in a separate reference file. Fits the 3 anchor ('content that should be separate is inline'; references not all resolving) better than 4, where references would be mostly clear.

Specificity

Multiple concrete actions are explicitly stated: 'A driver binds the config to Remotion input props, renders the 9:16 master, and derives a 1:1 center-crop with ffmpeg' plus 'Two gating checks run before render' with the exact conditions spelled out. Coverage of the skill's actions is comprehensive; not the 4 anchor only because no meaningful action is left out.

Completeness

Both 'what' (render the 4-beat offer ad, bind config, render 9:16 master, derive 1:1 crop, run gating checks) and 'when' ('Use for the motion-graphics-offer-ad format') are present. Not 5 because the 'when' clause names an internal format identifier rather than concrete natural trigger phrases; not 3 because the trigger is explicit, not merely implied.

Trigger Term Quality

Good keyword coverage: 'vertical (9:16)', 'music-only direct-response OFFER ad', 'kinetic-typography', 'Remotion', 'CTA'. However natural user synonyms like 'ad video', 'product ad', 'social/short-form video', or 'reel' are missing, and the sole trigger phrase 'Use for the motion-graphics-offer-ad format' is internal recipe jargon a user would not naturally say — closer to the 4 anchor ('a few natural terms missing') than 3, since the domain terms present are largely ones a user would say.

Distinctiveness Conflict Risk

Clear niche with distinct triggers — 'music-only direct-response OFFER ad', 'kinetic-typography film', 'motion-graphics-offer-ad format', Remotion-specific — that no generic video or image skill would claim. Minimal conflict risk.
