View source What is it?
Ponytail is the lazy senior developer who looks at fifty lines and replaces them with one. Installed as a skill, it makes Claude check whether a feature needs to exist, whether the codebase or the browser already does it, and only then write the minimum that works.
The author's benchmarks in Claude Code show roughly half the code, 45% fewer tokens and a quarter lower cost, while more risky logic ships with a test than before. Validation, security and accessibility are never cut.
It also adds /ponytail-review and /ponytail-audit, which review a change or rank your whole repo by what to fix first, plus a cost band above the Claude Code prompt.
Install in Claude Code
In Claude Code run /plugin marketplace add DietrichGebert/ponytail, then /plugin install ponytail@ponytail. It also installs into Codex, Cursor and about twenty other agents.
