The body is lean and assumes Claude's competence, with no generic explanations of ffmpeg/Remotion concepts; the verification prose conveys genuine domain gotchas that earn their tokens.

It provides fully executable, copy-paste-ready commands (bunx remotion render, ffmpeg with exact flags, avconvert, cp) with concrete targets rather than pseudocode.

A clear 3-step sequence (render master, convert to WebM/MP4, copy into both folders) is paired with a dedicated Verification section containing explicit validation checkpoints and failure-mode feedback, satisfying the explicit-validation anchor.

No bundle files exist and none are needed; the single self-contained file is organized into clear Workflow and Verification sections with no nested references, which satisfies the simple-skill allowance for a well-organized single-purpose skill.

Names multiple concrete actions (rendering, replacing, copying) tied to specific asset formats (transparent Chrome WebM, Safari MP4) and target folders (promo-pages, docs), matching the 'lists multiple specific concrete actions' anchor.

It explicitly answers both what (render/replace/copy homepage video assets) and when via an explicit 'Use when...' clause, satisfying the both-what-and-when anchor.

It includes several relevant real terms (Remotion, homepage, transparent Chrome WebM, Safari MP4), but the core trigger phrase 'creator strip videos' is internal project jargon a user would not naturally say, so it falls short of full natural-term coverage.

The niche is highly specific to Remotion homepage creator-strip video assets in promo-pages and docs, making it unlikely to trigger for the wrong skill.
