ponytail is a coding-agent skill focused on keeping engineering work simple. It encourages smaller solutions and less unnecessary code, helping an assistant make changes that fit the current problem without adding speculative complexity.
Keep a feature change proportionate
Use the guidance when a small request keeps turning into extra abstractions, configuration, or supporting code that the product does not need.
Review unnecessary complexity
Explore its review perspective when you want an agent to identify code that could be simplified and explain which parts add value to the requested behavior.
