The cut is biggest where there is a real over-build trap (date picker 404 to 23 lines, color picker 287 to 23, because it reaches for a native instead of a component) and near zero on code that is already minimal.
GitHub - DietrichGebert/ponytail: Makes your AI agent think like the laziest senior dev in the room. The best code is the code you never wrote.
Ponytail is an AI agent skill designed to make large language models (LLMs) think like a "lazy senior dev," prioritizing existing solutions and minimal code to prevent over-engineering. It guides agents through a decision-making ladder, focusing on reuse of standard libraries, native features, and installed dependencies before writing new code. This approach leads to significant reductions in code volume (up to 94%), cost (20%), and execution time (27%) in real-world benchmarks, while maintaining code safety. The tool offers plugins and integration for various AI agents and developer environments like Claude Code, GitHub Copilot, and Devin CLI.
