GitHub - shatskyy/ponytail: Makes your AI agent think like the laziest senior dev in the room. The best code is the code you never wrote.
Ponytail is a GitHub project designed to make AI agents adopt the mindset of a "lazy senior dev," drastically reducing the amount of code they generate. It works by implementing an "always-on" ruleset and a decision-making ladder that prompts the AI to prioritize existing solutions (stdlib, native features, dependencies) and only write new code as a last resort, focusing on necessity over verbosity. This approach reportedly leads to significantly less code, faster execution, and lower costs across various AI platforms, all while maintaining crucial aspects like security, validation, and accessibility.
