"Ponytail Lite" is Ponytail without the plugin madness.
Not to be confused with Ponytail's lite mode. This is a separate one-file version:
No plugin. No hooks. No MCP. No commands. No mode switching. Just copy AGENTS.md into the place your agent reads instructions. That's it.
Ponytail is a beautiful contradiction: an anti-overengineering tool delivered as a whole plugin ecosystem, with lifecycle hooks, slash commands, MCP, statuslines, adapter tests, and enough install paths to make a senior engineer stare silently at the wall.
Ponytail Lite is what happens after that senior engineer comes back from coffee:
AGENTS.md
Could you just copy AGENTS.md from Ponytail? Yes.
This repo exists so you do not have to walk past the plugin machinery to find the one file.
The AGENTS.md here is not a byte-for-byte copy. It is an opinionated cleanup of the original: same lazy senior dev idea, less plugin baggage, and guardrails rewritten for people who just want the file.
Copy AGENTS.md, or copy the same text into whatever your agent calls "project instructions" or "rules".
| Agent | Put the Ponytail Lite text here |

| Gemini CLI | AGENTS.md |
| GitHub Copilot | .github/copilot-instructions.md |
| GitHub Copilot CLI | AGENTS.md, .github/copilot-instructions.md, or ~/.copilot/copilot-instructions.md |
| Hermes Agent | Custom instructions / system prompt |
| Kiro | .kiro/steering/ponytail.md |
| OpenClaw | Custom skill / instruction file |
| OpenCode | AGENTS.md or OpenCode instructions |

Delete the file you copied.
If you pasted the text into a global instructions file, delete that paragraph.
No cleanup script. No leftover mode flag. No statusline entry. No hidden MCP server still thinking about your dependency graph.
