Ponytail: Lazy Senior Engineer Skill

Ponytail is a tool designed to encourage engineers to write minimal, efficient code by prioritizing simplicity over complexity. It follows a "laziness ladder"—checking if code already exists in the codebase, if standard libraries can solve the problem, or if a single line suffices—before writing new code. Benchmarks show this approach reduces code by 54% and tokens by 22% while maintaining safety and performance across 12 feature tasks.
