This project provides an AI agent persona designed to minimize code generation, promoting extreme efficiency and simplicity. Targeting developers who leverage AI for coding tasks, it aims to drastically reduce code volume, execution time, and cost by prioritizing existing solutions and minimal viable code.

How It Works

Ponytail operates on a strict, hierarchical decision-making process before generating any code. It first checks if the functionality is necessary (YAGNI), then if it exists in the standard library, native platform features, or installed dependencies. Only if these options are exhausted does it resort to writing a single line of code or the absolute minimum required to function. This "lazy, not negligent" approach ensures core aspects like security, validation, and accessibility are maintained while maximizing code reduction.

Quick Start & Requirements

Installation varies by AI agent framework:

• Claude Code: /plugin marketplace add DietrichGebert/ponytail
• Codex: codex plugin marketplace add DietrichGebert/ponytail or install via Open /plugins.
• Pi agent harness: pi install git:github.com/DietrichGebert/ponytail
• OpenCode: Add "plugin": ["./.opencode/plugins/ponytail.mjs"] to opencode.json.
• Other agents (Cursor, Windsurf, Cline, Copilot, Aider, Kiro): Copy specific rule files from the repository to the agent's configuration directory. No default prerequisites beyond integration with supported AI agent platforms are explicitly listed.

Highlighted Details

• Achieves 80-94% less code, 3-6x faster execution, and 47-77% lower cost compared to unconstrained agents, based on median results across multiple models and runs.
• Employs the philosophy: "The best code is the code you never wrote."
• Code shortcuts are explicitly marked with ponytail: comments, indicating potential upgrade paths.
• Includes commands like /ponytail-review to identify and suggest code deletions within diffs.

Maintenance & Community

No specific details regarding maintainers, sponsorships, or community channels (e.g., Discord, Slack) are provided in the documentation. Development includes scripts to ensure alignment of rule text copies across different agent configurations.

Licensing & Compatibility

The project is released under the MIT license, described as "The shortest license that works," suggesting broad compatibility for commercial use and integration.

Limitations & Caveats

The agent's core philosophy may lead to resistance or slow generation if users insist on complex, multi-line solutions that Ponytail deems unnecessary. Claims of "Zero bugs, zero CVEs, 100% uptime" are strong assertions requiring independent verification. Effectiveness is dependent on the underlying AI model's capabilities.
