Ponytail Gain

dietrichgebert/ponytail
11.8k installs105.1k stars
Summary

Shows you a compact ASCII scoreboard of ponytail's benchmark impact: 80–94% fewer lines, 47–77% lower cost, 3–6× faster, pulled from measured medians across five everyday tasks and three models. It's a one-shot display triggered by /ponytail-gain or "show ponytail impact," not a persistent mode. The honest part: it won't claim per-repo savings because you never wrote the bloated version to compare against. Instead it points you to /ponytail-debt for actual deferred shortcuts in your codebase. Use it when you need to explain the method's leverage to someone, or remind yourself why you're writing less.
