@goan999999: Codex 5.6 – Install This Skill to Write 90% Less Useless Code. Many people use Codex; once they input a requirement, the AI starts piling on components, installing dependencies, and writing a ton of code that isn't needed at all. Tokens get burned up, but the code becomes harder to maintain. This GitHub project is called pony…
Summary
This article introduces a GitHub project named ponytail, which acts as a plugin for Codex, forcing the AI to assess whether code truly needs to be written before coding, thereby reducing 90% of useless code, lowering token consumption, and improving code quality.

Ponytail
He says nothing. He writes one line. It works.
~54% less code (up to 94%) · ~20% cheaper · ~27% faster · 100% safe
Measured on real Claude Code sessions editing a real open-source repo (FastAPI + React), against the same agent with no skill. ~54% is the mean across 12 feature tasks (Haiku 4.5, n=4); it reaches 94% where an agent over-builds (a date picker) and is near zero where the code is already minimal. Ponytail keeps every safety guard, while a bare “write one-liners” prompt drops one.
(The earlier single-shot benchmark reported 80–94% as a flat figure; against a fair agentic baseline, that is the per-task ceiling, not the average.)
