Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

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'.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'vitest' ] || [ -L ~/.agents/skills/'vitest' ]; then echo 'A skill folder named vitest already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/jezweb/claude-skills' "$d" && git -C "$d" checkout --quiet '1260fa7439b36b18dbf16648ccc7fb44783f6c23' -- 'plugins/dev-tools/skills/vitest' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/dev-tools/skills/vitest' ~/.agents/skills/'vitest' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'vitest' ~/.claude/skills/'vitest' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
