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 well-structured, highly actionable lifecycle guide with executable code at every step and clean progressive disclosure to three real reference files. It loses a little on conciseness (light framing prose) and workflow clarity (the coverage-gate validation loop is referenced out rather than inline).
Suggestions
Tighten the Overview: drop the quoted Vitest docs line and reduce the two framework bullets to one-line role tags, since the Choosing-a-framework section already carries the decision logic.
Pull the coverage-gate verification loop ('run with a critical-path file below threshold, confirm non-zero exit') inline into Step 5 so the validate→fix→retry checkpoint isn't only in references/jest-coverage.md.
Trim gotcha prose where the code already self-documents (e.g. the `testEnvironment` default-change note can be a one-line comment in the config block).
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Dense and assumes Claude's competence — no 'what is a unit test' padding, and gotchas are non-obvious (testEnvironment default change across Jest versions, vi.mock hoisting leak) — but the Overview's framing bullets and the quoted Vitest docs line are slightly beyond the minimum needed, keeping it just under lean-perfect. | 4 / 5 |
Actionability | Copy-paste-ready throughout: install commands, complete `jest.config.js`/`vite.config.ts` blocks, runnable test files, mock/snippet code, and CI YAML with pinned flags (`--maxWorkers=2`, `vitest run --typecheck`) covering the common cases. | 5 / 5 |
Workflow Clarity | A clear Step 1–6 sequence (Install→First test→Config→Mocking→Coverage→Watch/CI) with concrete commands and a 'stop and ask' checkpoint in Authoring conventions, but the explicit validate→fix→retry feedback loop for the coverage gate lives in the reference rather than inline, leaving a minor validation gap. | 4 / 5 |
Progressive Disclosure | Clear overview with well-signaled one-level-deep references — `references/mocha.md`, `references/legacy-migration.md`, and `references/jest-coverage.md` (all verified present) — keeping deep dives (Mocha maintenance, legacy migration, coverage internals) out of the main body while the core lifecycle stays inline. | 5 / 5 |
