11%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 skill body is a hollow skeleton: a well-organized 'Use when' list is undermined by tautological exclusions, abstract instruction bullets, and a reference to a playbook file that does not exist in the bundle. An agent invoking this skill would have nothing actionable to execute.
Suggestions
Create the referenced resources/implementation-playbook.md (with framework-specific patterns for Jest/Vitest/Playwright, mocking, and CI setup) or remove the dangling reference.
Replace the abstract Instructions bullets with concrete, executable guidance: example test structures, commands like 'npx vitest run', and framework selection rules.
Delete the tautological 'Do not use this skill when' section and the repeated description line, and either inline a minimal quick-start pattern or delegate explicitly to the playbook.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Several sections are pure padding: the intro line repeats the frontmatter description verbatim, the 'Do not use this skill when' bullets are tautologies ('The task is unrelated to javascript testing patterns'), and the Instructions bullets ('Clarify goals, constraints, and required inputs') are generic filler Claude would do by default. This matches 'Noticeably verbose; several unnecessary explanations or padded sections' despite the short length. | 2 / 5 |
Actionability | The Instructions section is entirely abstract ('Apply relevant best practices and validate outcomes', 'Provide actionable steps and verification') with no code, commands, examples, or even a named framework — Jest, Vitest, and Playwright never appear. This matches 'Entirely vague or abstract; no concrete code or commands; only describes rather than instructs'. | 1 / 5 |
Workflow Clarity | There is no multi-step process at all — just unordered generic bullets with no sequence and no validation checkpoints for any of the claimed activities (test setup, mocking, CI integration). This matches 'Steps missing or incoherent; no sequence; no validation for risky operations'. | 1 / 5 |
Progressive Disclosure | The reference to 'resources/implementation-playbook.md' is clearly signaled, but the bundle contains no resources/, references/, scripts/, or assets/ directory, so the pointer is dangling and navigation fails. Combined with a body that holds no substantive content of its own, this fits 'Minimal structure' rather than the score-3 anchor where references are present and usable. | 2 / 5 |
