Individual skill
vitest
Set up Vitest testing in any project — detects type (Cloudflare Workers, React, Node, library), generates vitest.config.ts, test setup, utilities, and a sample test. Covers mocking patterns, coverage config, workspace setup, Jest migration. Use whenever the user mentions adding tests, setting up Vitest, configuring tests, migrating from Jest, fixing testing infrastructure, or asks 'how do I test this'.

# Vitest Setup
Detect the project type, generate the right Vitest configuration, and produce working test infrastructure. Not a reference card — this skill creates files.
## Workflow
1. **Detect** — scan the project to determine type and existing setup
2. **Configure** — generate vitest.config.ts tailored to the environment
3. **Scaffold** — create test setup, utilities, and a sample test
4. **Wire up** — add package.json scripts and TypeScript config
## Step 1: Detect Project Type
