# Ponytail — AI Coding Tool Review & Pricing

> Ponytail is a suite of AI agent skills designed to minimize unnecessary code by forcing agents to follow a ladder of resolution, preferring native browser or standard library features over new dependencies. It acts as an always-on ruleset that encourages writing only the minimum code necessary while ensuring critical validation, security, and accessibility are preserved.
