README

pi-co-authored-by

A Pi extension that automatically appends git trailers to commit messages when the agent runs git commit. Adds the model name and pi version so you always know which AI helped write the code.

Features

Co-Authored-By trailer — Credits the model that helped write the code:

Co-Authored-By: Claude Sonnet 4 <noreply@pi.dev>

Generated-By trailer — Records which version of Pi was used:

Generated-By: pi 0.63.2

Example commit:

fix: resolve null pointer

Co-Authored-By: Claude Sonnet 4 <noreply@pi.dev>
Generated-By: pi 0.63.2

Requirements

Pi coding agent

Install

pi install npm:pi-co-authored-by

Or try it without installing:

pi -e npm:pi-co-authored-by

You can also install from git:

pi install git:github.com/bruno-garcia/pi-co-authored-by

How it works

The extension hooks into Pi's tool_call event. When it detects a git commit -m command, it appends two extra -m flags to create git trailers with the current model name and pi version.

What	Value
`Co-Authored-By`	Model name (e.g., `Claude Sonnet 4`)
`Generated-By`	Pi version (e.g., `pi 0.52.12`)
