Conciseness

Mostly lean, table-driven, and free of generic-concept padding, but the 'Common anti-patterns' table restates points already made in earlier sections and a few rationale sentences could be trimmed.

Actionability

Highly actionable for a catalog skill: exact breakpoint widths (375/768/1280/1920 px), concrete threshold ranges (maxDiffPixels 50-200, threshold 0.2->0.3), specific tool flags, and worked naming examples — absence of code is appropriate here.

Workflow Clarity

Decision flows are clearly ordered (e.g. 'wait -> mask -> threshold' preference, baseline add/remove/update lifecycle, warn->block promotion after ~2 weeks) with explicit gating guidance, but there are no validate->fix->retry checkpoints because the skill drives decisions rather than performing operations.

Progressive Disclosure

Well-organized with clear section headers and one-level signaled references to sibling skills (e.g. playwright-snapshots references/responsive-breakpoints.md); no bundle files exist so everything is inline, and the duplicated anti-patterns table is a minor organization gap.

Specificity

Lists multiple concrete decisions — 'which Storybook stories or pages get baselines, how to choose breakpoints, when to mask vs adjust threshold, when to add or remove a baseline, and a decision matrix' — comprehensively covering the catalog's scope.

Completeness

Explicitly answers both what (the catalog of coverage decisions) and when ('Use when designing visual coverage for a new project or auditing an existing baseline set') with concrete trigger phrases.

Trigger Term Quality

Includes natural domain terms and synonyms a user would actually say — 'visual regression coverage', 'Storybook stories', 'breakpoints', 'baselines', plus the full set of tool names 'Percy / Chromatic / Playwright / Storybook test-runner'.

Distinctiveness Conflict Risk

Carves a clear niche — engine-agnostic 'which baselines and where' decisions — distinct from the named engine-specific skills, minimizing wrong-skill triggering.
