The body is lean and assumes Claude's competence — it jumps straight to 'bun i && bun run build' and 'cd packages/docs && bun run start' with no padding or restating of concepts Claude already knows.

Provides copy-paste-ready executable commands for the build and start steps; the only conditional guidance (tool_search for the in-app browser) is inherently situation-dependent rather than vague.

A clear numbered sequence for a simple single-task skill, with built-in adaptation cues (read server output for the URL, follow the printed port). This is not a destructive or batch operation, so missing explicit validation checkpoints does not cap the score per the simple-skills note.

Under 50 lines with no need for external references, organized into Overview and Workflow sections — meeting the rubric's allowance that short, self-contained skills can score 3 with well-organized sections alone.

Names multiple concrete actions — 'Start the Remotion docs site and open it in the Codex browser' — which matches the score-3 anchor listing several specific concrete actions rather than the score-2 partial coverage.

Explicitly answers both what it does ('Start the Remotion docs site and open it in the Codex browser') and when to use it via a clear 'Use when...' clause, matching the score-3 anchor exactly.

Covers natural phrasings a user would actually say — 'invokes /docs or $docs', 'asks to launch the local documentation site', 'preview docs changes in Docusaurus' — giving good breadth of natural trigger terms.

The Remotion + Docusaurus + Codex-browser niche with /docs and $docs triggers is clearly distinct and unlikely to fire for unrelated skills.
