You MUST use this when configuring, writing, debugging, running, migrating, or auditing Vitest tests in JavaScript/TypeScript projects - Vite, Vue, Nuxt, React, Next.js, Node libraries, workspaces, coverage, mocks, snapshots, flaky tests, CI parity, or Jest migration.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Vitest

Use this skill to add, fix, or run Vitest tests without turning the task into a Vitest API reference lookup.

**Helper Scripts Available**:
- `scripts/inspect_vitest.py` - Reports normalized package, runtime, configuration, framework, filesystem-candidate, and diagnostic signals without exposing repository-controlled text
- `scripts/run_vitest.py` - Runs Vitest through the detected package manager with useful defaults

`<skill>` means the path to this local skill folder. Run helper scripts with `--help` when usage is unclear or before first use in a session. Prefer using helper scripts as black-box tools. Read or modify their source only when debugging the skill itself or when behavior is unclear.

## Decision Tree

```
User task -> Is this an existing project?
    - Audit -> Read: references/audit.md
               Run: python <skill>/scripts/inspect_vitest.py --root <project>
               Collect evidence before proposing changes.
    - Yes -> Run: python <skill>/scripts/inspect_vitest.py --root <project>
             Use detected framework, config, aliases, and package manager.
    - No / new setup -> Inspect package.json manually if present, then create the

How to install

The exact contents, by fingerprint
mdr add sentimony/skills/vitest@sha256:bf2890be2dd71e24

The line at the top of this page pins the label v1.4.2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
