Ponytail is a plugin that makes coding agents write the least code that works. Before adding anything, it checks whether the change is needed, already exists, or can use the stdlib or a native API. Same behavior, fewer lines to own.
Make new code a last resort with smarter AI dev tools. Try Cursor for an agentic pair‑programmer, Claude Code for deep‑context reasoning, Codex 3.0 by OpenAI for build‑test‑debug autopilot, or Windsurf for an agentic IDE.
