Create a highly optimized prompt for an AI agent based on user input. Use when the user asks to improve, rewrite, or optimize a prompt, or when they want to learn how to write better prompts for agentic AI workflows. Requires OPENROUTER_API_KEY and/or OPENAI_API_KEY environment variables.

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/'prompt-engineer' ] || [ -L ~/.agents/skills/'prompt-engineer' ]; then echo 'A skill folder named prompt-engineer already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/onfire7777/universal-ai-skills-library' "$d" && git -C "$d" checkout --quiet '2a76bf42ce5c860adf8d0f3fcf3f6804109ac65b' -- 'skills/prompt-engineer' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/prompt-engineer' ~/.agents/skills/'prompt-engineer' && 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-engineer' ~/.claude/skills/'prompt-engineer' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
