Turn plugin-eval findings into a concrete rewrite brief for a Codex skill. Use when the user already evaluated a skill and now wants Codex to improve it, especially after asking what to fix first.

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/'improve-skill' ] || [ -L ~/.agents/skills/'improve-skill' ]; then echo 'A skill folder named improve-skill already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/openai/plugins' "$d" && git -C "$d" checkout --quiet 'd420d13051bffe4543ed39e30fa46b87148e47dd' -- 'plugins/plugin-eval/skills/improve-skill' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/plugin-eval/skills/improve-skill' ~/.agents/skills/'improve-skill' && 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/'improve-skill' ~/.claude/skills/'improve-skill' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
