- Ponytail Teach your coding agent to write less code, like a senior dev
Ponytail is a plug-in skill that teaches AI coding assistants to write less code: the agent learns to prefer the shortest change that works — the project frames it as thinking "like the laziest senior dev in the room." The creator measured it on real Claude Code sessions across twelve feature tasks and reports about 54% less code on average (up to 94% where the agent would otherwise over-build, as with a date picker), roughly 20% lower cost and 27% faster runs, with every safety guard kept.
