Quality

Content

75%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A well-structured, lean reference that provides executable fixes and a clear review workflow without over-explaining known concepts. It scores solidly across all dimensions with only minor room for tightening and broader example coverage.

Suggestions

Consolidate the "rule categories by priority" table and the "quick reference" section to remove the duplicated category listing and tighten conciseness.

Add one or two more concrete before/after code examples (e.g., will-change promotion, IntersectionObserver pause) to broaden actionability coverage.

Make the review-mode workflow's checkpoints more explicit (e.g., a numbered enforce-then-report sequence) to push workflow clarity toward 5.

DimensionReasoningScore

Conciseness

The body is lean with terse bullet rules and a compact glossary, assuming Claude's competence; the only redundancy is the "rule categories by priority" table restating categories later expanded in "quick reference".

4 / 5

Actionability

Provides executable CSS and JS examples (transform vs width, scroll-timeline, FLIP measurement) and directive rules, with minor gaps in coverage of additional cases.

4 / 5

Workflow Clarity

The review mode defines a clear output structure (violations, why it matters, concrete fix) and "review guidance" sequences enforcement, with most checkpoints present; not a destructive/batch skill so the validation cap does not apply.

4 / 5

Progressive Disclosure

No bundle files exist; content is a single well-organized file with clear section headers and appropriately self-contained material, with only minor organization gaps.

Description

87%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong description that explicitly pairs a concrete capability statement with natural trigger phrases. It is comprehensive on completeness and distinctiveness, with only minor room to add synonyms for trigger terms.

DimensionReasoningScore

Specificity

"Audit and fix animation performance issues including layout thrashing, compositor properties, scroll-linked motion, and blur effects" names the domain plus four concrete issue categories, but the two verbs (audit, fix) are broader than the anchor-5 example's distinct discrete actions.

4 / 5

Completeness

Explicitly answers both what ("Audit and fix animation performance issues including...") and when ("Use when animations stutter, transitions jank...") with concrete trigger phrases.

5 / 5

Trigger Term Quality

"Use when animations stutter, transitions jank, or reviewing CSS/JS animation performance" captures natural user phrases, but omits common synonyms like "laggy", "frame drops", or "60fps".

4 / 5

Distinctiveness Conflict Risk

Targets a clear niche (animation performance) with distinct triggers and minimal overlap risk with unrelated skills.
