Ponytail
Dietrich Gebert
Ponytail teaches your coding agent to look for the simplest safe solution before it writes new code. It asks whether the feature is needed, whether the project already solves it, and whether a built-in tool or installed dependency can do the job. Because the agent writes and reviews less unnecessary code, it can save tokens, avoid extra dependencies, and leave smaller changes for you to understand. It does not mean skipping tests, security, accessibility, or error handling; those safeguards remain part of the work.
Best for
People whose coding agent tends to over-engineer simple requests, create unnecessary abstractions, or add dependencies too quickly.

Why it is interesting
Its decision ladder makes reuse and minimal code an always-on habit, with separate commands for reviewing a change or auditing a whole repository.
Check before installing
The Claude Code plugin uses lifecycle hooks and requires Node on the non-interactive PATH. Minimalism should not remove required validation, accessibility, or safety controls.
