Conciseness

The body is mostly concrete PASS/FAIL code examples that earn their tokens, but it includes unnecessary explanation of concepts Claude already knows — the KISS/DRY/YAGNI/readability principles block and aphorisms like '代码被阅读的次数远多于被编写的次数' — and the PASS/FAIL doubling on basic naming examples could be tightened. It is not severely padded (score 2) because the bulk is actionable code, but it carries more than minor over-explanation.

Actionability

It provides extensive concrete, executable TypeScript/React snippets covering naming, error handling, async, types, components, hooks, API design, validation, memoization, and testing — mostly copy-paste ready. Minor gaps (placeholder '// Implementation' bodies in getMarket/searchMarkets and empty '() => { }' test bodies) keep it just below fully executable at score 5.

Workflow Clarity

This is a reference/standards document, not a sequenced process: sections are roughly ordered (principles → language → React → API → file org → comments → perf → testing → smells) but there are no defined operational steps or validation checkpoints for applying the standards, and validation is absent. It is above score 1 (content is coherent and has an activation list) but lacks the sequenced steps required for score 3.

Progressive Disclosure

The body is well-organized into a clear hierarchy of headers, but everything is inlined in a single ~530-line SKILL.md with no external references or bundle files — content that could be split out (detailed API design, code-smell catalog, JSDoc guide) lives inline. It is better than 'minimal structure' (score 2) due to the clear headers, but has no signaled one-level-deep references required for score 4.

Specificity

The description names the domain ('TypeScript、JavaScript、React和Node.js开发') but the actions ('通用编码标准、最佳实践和模式') are abstract categories rather than concrete actions like 'enforce naming conventions' or 'review code'. It is not entirely vague (it specifies a stack) but the actions are minimal and generic, fitting score 2 rather than 3 which requires 1-2 concrete actions.

Completeness

There is a clear 'what' (coding standards/best practices/patterns for the stack) but no 'when' — there is no 'Use when...' clause or equivalent explicit trigger guidance, which per the rubric caps completeness at 3. It is above score 2 because the 'what' is not purely vague, but cannot reach 4 without any explicit 'when'.

Trigger Term Quality

It includes natural terms users say — the named technologies (TypeScript, JavaScript, React, Node.js) plus '编码标准' (coding standards) and '最佳实践' (best practices) — but misses common variations a user would naturally say such as 'code review', 'refactoring', 'linting', or 'conventions'. This matches 'some relevant keywords but missing common variations or synonyms'.

Distinctiveness Conflict Risk

The specified tech stack (TS/JS/React/Node) gives it a somewhat specific niche, but '通用编码标准' (general coding standards) is a broad scope with real overlap risk against language- or framework-specific skills. It is not very broad (score 2) thanks to the named stack, but not mostly distinct (score 4) because general standards for a common stack overlaps several related skills.
