Makes your AI agent think like the laziest senior dev in the room. The best code is the code you never wrote.
What ponytail is
ponytail is the only arm that cuts every metric, and the only one that stays fully safe while doing it. 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. Full method, per-task tables, and limitations: benchmarks/results/2026-06-18-agentic.md.

GitHub Copilot Business costs $19 per user monthly. This does it free. Your AI agent now ships simpler solutions, writes 10x less code for you to maintain, and kills over-engineered nonsense before it spreads. That's Ponytail. 73,729 GitHub stars. It makes Claude and Cursor think like the laziest senior dev—the one who knows the best code is the code you never wrote. What's the worst over-engineering you've seen an AI produce? Comment your horror story.
