Ponytail is a ruleset/plugin that makes AI coding agents (Claude Code, Cursor, Codex, Copilot, Gemini CLI, and 14+ others) write the least code that works, following YAGNI and reuse-first principles. It ships as an installable agent skill/plugin that reduces generated code volume, token usage, and cost while preserving safety and error handling.

Use cases

• stop my AI agent from over-engineering simple features
• make Claude Code write less code
• reduce LLM token costs when coding with an agent
• enforce YAGNI principles in AI-generated code
• get my coding agent to reuse existing helpers instead of adding dependencies
• speed up AI coding sessions by generating fewer lines
• install a minimalism ruleset for Cursor or Windsurf

When to choose

• your AI agent habitually over-builds, adds unnecessary dependencies, or writes speculative abstractions
• you want lower token costs and faster agent sessions without losing safety guards
• you use Claude Code, Cursor, Codex, Copilot, Gemini CLI, or similar agents and want a drop-in ruleset

When to avoid

• you need your agent to build comprehensive, feature-rich implementations on the first pass
• you don't use an AI coding agent, since ponytail only works as agent rules/skills
• your codebase already enforces minimalism through review or existing conventions
