DietrichGebert/ponytail is a GitHub repository providing a prompt strategy that forces AI coding agents to minimize code generation. Benchmarks on real FastAPI and React tasks show an average 54% reduction in lines of code, with peaks up to 94% where agents typically over-engineer solutions. The approach claims lower costs and faster execution while maintaining safety guardrails that standard minimal-prompt techniques often lose.
- Targets AI agent bloat by enforcing minimal code output per task.
- Measures 54% mean code reduction across 12 feature tasks in tests.
- Maintains safety guardrails unlike bare 'write one-liners' prompts.
- Optimized for Haiku 4.5 with real open-source repo editing sessions.
