TL;DR
Ponytail is an AI agent 'skill' (system prompt / instruction set) that teaches AI coding agents to prefer simpler, minimal solutions — like a senior developer who replaces 50 lines with one. It works with 13 agent frameworks and claims 80-94% less code, 3-6x faster output, and 47-77% cheaper token usage. AI coding agents tend to over-engineer solutions, adding unnecessary dependencies and boilerplate. Ponytail addresses this by injecting a 'laziness-as-craft' heuristic that pushes agents to use native platform features and the simplest viable approach, reducing cost and complexity without sacrificing correctness or safety.

Caption: this skill mimics that one senior dev with glasses and ponytail, helps you save tokens and make better architecture decisions
pair it with /grill-me, worth a shot! #computerscience #skill #tech

Visit the GitHub repo at https://github.com/DietrichGebert/ponytail and follow the README to add the Ponytail skill to your AI agent. Pair it with the /grill-me skill for architectural critique. The skill works with 13 agent frameworks out of the box under the MIT license, so no installation beyond copying the prompt/config is required.
