56%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The body delivers genuinely actionable, executable testing guidance anchored by a clear 7-step TDD workflow, but it is overlong for a SKILL.md: coverage requirements are restated in several sections, generic best-practice lists pad the token budget, and the framework-specific patterns and mock recipes should live in reference files. Consolidating duplicates and splitting the detailed patterns out would lift both conciseness and progressive disclosure.
Suggestions
State the 80% coverage requirement once (in the core-principles or coverage section) and delete the repetitions in step 7, the coverage-verification section, and the success-metrics section.
Move the framework-specific patterns (Jest/Vitest unit, Playwright e2e, API integration, and the Supabase/Redis/OpenAI mock recipes) into a references/ file such as TEST_PATTERNS.md, keeping SKILL.md as a workflow overview with one compact example per test type.
Cut the 10-item generic best-practices list and the closing motivational line — both restate testing knowledge Claude already has and add no skill-specific value.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The ~435-line body has noticeable padding: the 80% coverage requirement is repeated in at least four sections ("核心原则", "步骤 7", "测试覆盖率验证", "成功指标"), the 10-item "最佳实践" list restates well-known testing practices Claude already knows (one assertion per test, descriptive test names, arrange-act-assert), and the closing motivational line "测试不是可选的" is filler. This matches anchor 2 ('several unnecessary explanations or padded sections') rather than anchor 3, because the redundancy is repeated across whole sections, not just occasional loose sentences. | 2 / 5 |
Actionability | Most guidance is executable: real commands ("npm test", "npm run test:coverage"), runnable Jest/Vitest, Playwright, and Next.js API test snippets, concrete Supabase/Redis/OpenAI mock recipes, and a copy-paste Jest coverageThresholds config. It falls short of anchor 5 because several workflow snippets are stubs ("// Test implementation", "// Implementation here") and one integration test ("handles database errors gracefully") is an empty shell. | 4 / 5 |
Workflow Clarity | The 7-step TDD workflow (user journey → generate tests → run and expect failure → implement → run and expect pass → refactor → verify coverage) is clearly sequenced with explicit checkpoints at steps 3, 5, and 7. It is anchor 4 rather than 5 because there is no error-recovery feedback loop (e.g., what to do when tests fail after refactoring or coverage falls short) and no checklist tying the steps back to validation. | 4 / 5 |
Progressive Disclosure | No bundle files (references/, scripts/, assets/) exist, and the skill is a single 435-line file that inlines per-framework test patterns (Jest, Playwright, API) and mock recipes that clearly belong in separate reference files — matching anchor 3 ('content that should be separate is inline'). It is not anchor 2 because the file has clear, consistently headed sections and is navigable; it is not anchor 4 because nothing at all is split out for a skill of this size. | 3 / 5 |
