Conciseness

Lean and efficient with zero padding: every line carries repo-specific facts Claude cannot know (the file key "oJQ7t9q4e8oHzLZKuki7k1", "only slots accept appendChild on an instance", "new nodes land on the current page, which may be the cover"). It assumes Claude's competence and never explains concepts it already knows, matching the score-5 anchor.

Actionability

Concrete and mostly executable: real commands ("node prototypes/kit/build.ts <name>", the Playwright pnpm path) and named API calls ("setCurrentPageAsync", "importComponentSetByKeyAsync", "figma.variables.setBoundVariableForPaint"). Not 5 because the Figma push flow lacks a copy-paste-ready example script for the common case — guidance is procedural rather than executable end-to-end.

Workflow Clarity

Both edit/republish and Figma-pull are numbered sequences with explicit validation checkpoints ("Zero page and console errors, and look at a screenshot of what changed"; "screenshot the section with get_screenshot, and fix what's off") and error-recovery loops ("A failed script rolls back, so re-read before retrying"). The destructive/batch operations (republish, commit and push) are all gated behind verification, matching the score-5 anchor.

Progressive Disclosure

Well-signaled one-level-deep references ("prototypes/README.md is the index... Read it first", "<name>/changes.json", "<name>/prototype.json", "kit/add-icons.ts") and clear section structure. Not 5: the Figma push detail (~15 lines of component/color/API-call rules) sits inline where a reference file would fit, a minor organization gap matching the score-4 anchor rather than a fully split structure.

Specificity

Lists several concrete actions ("Open, edit, republish, and Figma-sync the template prototypes") with the named domain and apps ("Claude artifacts of Design, Chat, Slides, Clips, Analytics"). Not 5 because "Figma-sync" is a compound action and the build/verify loop is folded into "republish" rather than enumerated — minor gaps in coverage, matching the score-4 anchor.

Completeness

Explicitly answers both questions: what ("Open, edit, republish, and Figma-sync the template prototypes in prototypes/") and when ("Use when asked to open or change a prototype, push one to its app's Figma page, or pull Figma edits back into it") with concrete trigger phrases, matching the score-5 anchor exactly.

Trigger Term Quality

The when-clause uses natural phrases users would actually say: "open or change a prototype", "push one to its app's Figma page", "pull Figma edits back into it". A few natural synonyms and variations are missing, so it fits the score-4 anchor (good coverage, a few natural terms missing) rather than the comprehensive score-5 anchor.

Distinctiveness Conflict Risk

A clear niche with distinct triggers: "template prototypes in prototypes/", named apps, and bidirectional Figma page sync. The vocabulary (prototypes, Figma page, republish to the artifact link) is unlikely to fire for the wrong skill, matching the score-5 anchor.
