86%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.
A tightly organized, highly actionable reference with executable code at every step and a clean one-level-deep bundle structure. Its only weakness is mild over-explanation in the Overview/framework-comparison prose and a missing explicit post-authoring verification checkpoint.
Suggestions
Tighten the Overview and 'Choosing a framework' prose to the decision rule itself; drop the restated Jest/Vitest feature lists Claude already knows.
Add an explicit validation step to the authoring workflow (e.g. 'Run the new test and confirm it fails without the change / passes with it') to close the workflow-clarity gap.
Trim the Vitest doc quote in the Overview to a one-line rationale for choosing Vitest in a Vite project.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is dense and mostly assumes Claude's competence (tight code blocks, gotchas, an anti-pattern table), but the Overview and framework-comparison prose restates Jest/Vitest characteristics Claude largely already knows, so it sits just below the lean/efficient anchor. | 4 / 5 |
Actionability | Provides copy-paste-ready install commands, full `jest.config.js`/`vite.config.ts` blocks, executable mock and fake-timer snippets, coverage commands, and a CI YAML block covering the common cases, matching the fully-executable anchor. | 5 / 5 |
Workflow Clarity | Steps 1-6 (Install → First test → Configuration → Mocking → Coverage → Watch/CI) are clearly sequenced with checkpoints like 'detect the framework, never assume' and CI guards (`vitest run`, `--typecheck`), but there is no explicit 'run and verify the test passes' validation loop in the authoring steps, leaving it just below the top anchor. | 4 / 5 |
Progressive Disclosure | SKILL.md is an overview that pushes deep material to well-signaled one-level-deep references (references/mocha.md, legacy-migration.md, jest-coverage.md, all present in the bundle), with content appropriately split and easy to navigate, matching the top anchor. | 5 / 5 |
