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/'codex-agent-setup' ] || [ -L ~/.agents/skills/'codex-agent-setup' ]; then echo 'A skill folder named codex-agent-setup already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/b-open-io/prompts' "$d" && git -C "$d" checkout --quiet 'f4b302aadb0c99023b03e1f1b38ffed3697fbedf' -- 'skills/codex-agent-setup' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/codex-agent-setup' ~/.agents/skills/'codex-agent-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/'codex-agent-setup' ~/.claude/skills/'codex-agent-setup' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
