DietrichGebert/ponytail
Ponytail is a configuration system that injects a 'lazy senior developer' persona into AI coding assistants to enforce minimal, efficient code generation. It provides a unified ruleset and skill set that can be activated across multiple platforms, including Claude, Copilot, and OpenCode, via hooks, extensions, and an npm package. The system includes comprehensive benchmarking tools to measure code size, correctness, and behavior against baselines and competitors.

About this page
- The description of this project is derived from its own commit history, not from its README.
- The score is its highest published measurement, taken on 2 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
- Measured at commit 16f29800fd — the exact code this score is about.
- Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
