Turns a Jeffrey profile into concrete code changes in the current repository — maps the hottest CPU, wall-clock, allocation and blocking frames, the slowest traces, the waiting on locks and I/O, the database and HTTP work, and a heap dump's leak suspects to real source, recommends minimal behaviour-preserving edits, applies them on request and verifies with the tests and a re-profile.

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/'optimize-code' ~/.claude/skills/'optimize-code' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
