Quality

Content

87%

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

The body is concise, actionable, and well-structured with a properly signaled single-level reference, but it lacks explicit verification/measure-remeasure checkpoints that a performance-optimization workflow should provide.

Suggestions

Add a brief validate/measure step to the critical rules, e.g. confirm re-render reduction or bundle-size delta with the profiler before considering an optimization done.

Since executeBatched already appears in references/rules/performance.md, consider keeping only the call-site example in the body and deferring the full implementation to the reference to avoid duplication.

DimensionReasoningScore

Conciseness

The body is lean — a quick-reference table, one well-chosen BAD/CORRECT code example, a built-in-optimizations table, and a single pointer to the detailed reference — with no explanations of concepts Claude already knows, so every section earns its place.

3 / 3

Actionability

It provides fully executable, typed TypeScript (the generic executeBatched with PromiseSettledResult returns) plus concrete numeric guidance ('Limit to 3-5', concurrency = 3, windowSize={5}), making the examples copy-paste ready.

3 / 3

Workflow Clarity

Rules are well-organized by category with clear BAD/CORRECT contrast and a useful 'Already Optimized - NO ACTION NEEDED' guard, but there is no measure-optimize-remeasure validation loop (e.g. profiler-based verification) for a performance skill, leaving checkpoints implicit.

Progressive Disclosure

SKILL.md is a clear overview pointing exactly one level deep to a verified references/rules/performance.md, with a 'Topics covered' list signaling the reference's contents and Related Skills cross-links for navigation.

Description

72%

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 well-targeted to a clear niche with strong natural trigger terms, but it omits an explicit 'Use when...' clause, leaving the invocation trigger only implied and capping completeness.

Suggestions

Add an explicit trigger clause, e.g. 'Use when optimizing React/React Native performance, debugging re-renders, memory leaks, or reducing bundle size.'

Reframe the topic list as concrete actions (e.g. 'reduce re-renders, apply memoization, switch to FlashList, fix memory leaks, shrink bundle size') to lift specificity to the top anchor.

DimensionReasoningScore

Specificity

Names a concrete domain (React/React Native performance) and specific subtopics ('re-renders, memoization, FlashList, memory leaks, and bundle size'), but these are capability topics framed as nouns rather than concrete verb-actions like 'extract', 'fill', 'merge', so it stops short of the level-3 anchor.

2 / 3

Completeness

It clearly states what the skill does (performance optimization for React/RN with listed topics) but lacks any explicit 'Use when...' trigger clause, so the 'when' is only implied — per the judging guidelines a missing trigger clause caps completeness at 2.

2 / 3

Trigger Term Quality

Terms like 're-renders', 'memoization', 'FlashList', 'memory leaks', 'bundle size', and 'Performance optimization' are exactly the natural language a developer would say when needing this skill, giving good coverage rather than jargon-only or generic phrasing.

3 / 3

Distinctiveness Conflict Risk

Scoping to React/React Native performance with OneKey-specific items like FlashList gives it a clear niche with distinct triggers unlikely to fire for unrelated skills.
