About
Ponytail is an agent skill that forces your AI coding agent to stop at the simplest solution that works: reuse existing code, reach for the stdlib, use native platform features, prefer one-liners — and only then write the minimum. Based on the "lazy senior dev" archetype. Measured on real Claude Code sessions editing a real FastAPI+React repo: 54% fewer lines of code (up to 94% on over-build traps like date pickers), while keeping every safety guard. Works with Claude Code, Codex, Copilot CLI, Cursor, Windsurf, Cline, Gemini, and 20+ other agents.
