Why we included this project

Most coding agents default to building too much, and Ponytail is a skill that pushes back. You drop it into Claude Code or another agent runtime and it steers the model toward the smallest change that works, the one line instead of the fifty-line abstraction. The YAGNI mindset gets encoded as a reusable skill, so every session starts with the same bias toward minimal, maintainable code without you having to re-prompt. The repo includes benchmarks you can reproduce, measured on real Claude Code sessions, so you can see whether the effect holds on your own workloads. It's a prompt and workflow layer rather than a model or framework.
