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

Read this first, before the reeval skill, whenever you're asked to set up, install, add, try or get started with reeval (the eval runner for coding agents), in a project or an empty directory, including "set up reeval here" and "add evals". It detects what's set up, asks what to evaluate, installs reeval, writes one to three small evals that show its value (a skill with and without, when the project has skills), runs `reeval doctor` for keys and Docker, and explains the results.
Works with any agent that supports SKILL.md skills.

Install
Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'setup' ] || [ -L ~/.agents/skills/'setup' ]; then echo 'A skill folder named setup already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/invertase/reeval' "$d" && git -C "$d" checkout --quiet '1b778a9c674f9869f4c761c1bc4a1362db3f3804' -- 'skills/setup' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/setup' ~/.agents/skills/'setup' && 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/'setup' ~/.claude/skills/'setup' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
