ponytail
Helps AI agents review code, reduce overengineering, and preserve safety and quality
About ponytail
ponytail is for teams developing with AI agents, offering current-diff overengineering reviews, full-repository code-bloat audits, and guidance for simplification decisions. It follows a ladder: confirm the need first, reuse existing code, prefer the standard library and native capabilities, then write the least code. It emphasizes keeping validation, error handling, security, and accessibility requirements intact. The official benchmark covers 12 FastAPI + React feature tasks and reports less code, fewer token, lower cost, and faster speed while maintaining security.
