Quality

Content

68%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.

The body is lean, actionable, and well-structured with a valid one-level-deep reference. It functions as a reference catalog rather than a sequenced workflow, so it lacks explicit validation checkpoints.

Suggestions

Add a brief decision/verification step for applying optimizations (e.g., 'Profile before and after; confirm re-render count dropped') to strengthen workflow clarity.

De-duplicate the executeBatched implementation between SKILL.md and references/rules/performance.md so the overview stays lean.

DimensionReasoningScore

Conciseness

The body is efficient with a quick-reference table, focused BAD/CORRECT code, and a built-in optimizations table; it avoids explaining basic React concepts, with only minor repetition of the executeBatched snippet.

4 / 5

Actionability

Provides copy-paste-ready executable code (executeBatched with concurrency limit) and concrete values (windowSize={5}, concurrency=3) in a BAD/CORRECT contrast, with only minor gaps in coverage of the listed categories.

4 / 5

Workflow Clarity

Content is organized as a patterns/reference catalog with a when-to-use table rather than a sequenced multi-step workflow, and there are no explicit validation checkpoints, which fits the anchor for a clear-but-checkpoint-missing structure.

3 / 5

Progressive Disclosure

SKILL.md acts as an overview with a clearly signaled, one-level-deep, real reference ([performance.md](references/rules/performance.md), 779 lines) and a topic list; minor gap is the executeBatched code being duplicated across both files.

Description

66%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.

The description is specific and uses natural technical terms, but omits any explicit 'Use when...' trigger guidance, which limits its completeness. It is otherwise distinct and reasonably comprehensive.

Suggestions

Add an explicit 'Use when...' clause naming concrete trigger phrases (e.g., 'Use when the user reports jank, slow lists, re-renders, or bundle size issues in React/React Native').

Include common synonyms/variations users might say (e.g., 'lag', 'jank', 'AppHang', 'slow scrolling') to broaden trigger term coverage.

DimensionReasoningScore

Specificity

Names the domain ('Performance optimization for React/React Native') and lists several concrete subtopics ('re-renders, memoization, FlashList, memory leaks, and bundle size'), giving broad coverage though framed as topics rather than explicit actions.

4 / 5

Completeness

Has a clear 'what' (performance optimization areas for React/React Native) but no 'Use when...' clause or equivalent trigger guidance, which caps completeness at 3 per the guidelines.

3 / 5

Trigger Term Quality

Includes natural developer terms like 're-renders', 'memoization', 'memory leaks', and 'bundle size' that users actually say, but lacks synonyms or explicit trigger phrasing.

4 / 5

Distinctiveness Conflict Risk

Targets a clear performance niche, though it overlaps somewhat with the related /react-native-best-practices skill referenced in the body.
