Ponytail makes AI agents write less code
Ponytail is a GitHub project that makes an AI agent check whether code is needed before writing it. Its README says the agent should use standard tools, built-in browser features, or already installed tools first, and only write the smallest code that works after that. The project claims that in 5 coding tasks, tokens dropped by 16% and speed was about 4 times faster.
