Content
80%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A strong, executable skill body with lean prose and copy-paste code across a clear 9-step sequence. Its main gaps are the absence of explicit validation checkpoints in the workflow and an inline-everything structure that underuses progressive disclosure.
Suggestions
Add an explicit validation/feedback step, e.g. after Step 7 type-checking and Step 8 coverage: 'run vitest run --typecheck --coverage; if thresholds or type errors fail, fix and re-run before committing'.
Move the longer detail blocks (Step 3 full coverage config, Step 6 browser mode, Step 9 CI yaml) into a reference file such as CONFIG.md and keep SKILL.md as a lean overview with one-level links.
Trim a few restated rationales (e.g., the v8-vs-istanbul note appears in both Step 3 prose and the Anti-patterns table) to tighten token efficiency.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Lean prose that assumes competence ('Vitest reads your vite.config.* by default', 'Migration from Jest: replace jest. with vi.') and avoids explaining what test frameworks or ESM are; nearly every token earns its place. | 3 / 3 |
Actionability | Every step ships executable, copy-paste-ready code or commands (npm install -D vitest, vite.config.ts blocks, vi.mock/vi.spyOn snippets, vitest run --coverage), matching the fully-executable anchor. | 3 / 3 |
Workflow Clarity | The 9 steps are clearly sequenced, but there are no explicit validation/checkpoint steps or error-recovery feedback loops (e.g., 'run tests; if type errors, fix and re-run'), which keeps it below the top anchor. | 2 / 3 |
Progressive Disclosure | Well-organized into sections with a one-level References list, but at ~250 lines all config detail, mocking, browser-mode, and CI content is inline rather than split into reference files, so it is not a lean overview pointing to deeper materials. | 2 / 3 |
