Install

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

if [ -e ~/.agents/skills/'prompt-validator' ] || [ -L ~/.agents/skills/'prompt-validator' ]; then echo 'A skill folder named prompt-validator already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/event4u-app/agent-config' "$d" && git -C "$d" checkout --quiet '3445cf41d6db4b369392dc6fbf7e78a2774e17b5' -- 'src/skills/prompt-validator' && mkdir -p ~/.agents/skills && cp -R "$d"/'src/skills/prompt-validator' ~/.agents/skills/'prompt-validator' && 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/'prompt-validator' ~/.claude/skills/'prompt-validator' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
