Agents Md Generator — Git skill for Claude Code

agents-md-generator

[日本語](README-ja.md)

A shell wrapper that automatically creates a starter `AGENTS.md` (with `CLAUDE.md` symlink) when you clone an empty repository.

Blog post: [AGENTS.mdを自動で育てる仕組みを作った](https://nyosegawa.github.io/posts/agents-md-generator/)

Why

Every new repository needs an `AGENTS.md` — the [open standard](https://agents.md/) for guiding AI coding agents (Cursor, Zed, Codex, Gemini CLI, GitHub Copilot, etc.). Claude Code reads `CLAUDE.md`. Setting up both manually every time is tedious.

This wrapper plants the seed automatically. You just grow it as your project evolves.

Setup

Add to your `.bashrc` or `.zshrc`:

source /path/to/agents-md-seed.sh

If you use ghq:

ghq get nyosegawa/agents-md-generator
# .zshrc / .bashrc
source "$(ghq root)/github.com/nyosegawa/agents-md-generator/agents-md-seed.sh"

Or download directly:

curl -sL https://raw.githubusercontent.com/nyosegawa/agents-md-generator/main/agents-md-seed.sh -o ~/.agents-md-seed.sh
echo 'source ~/.agents-md-seed.sh' >> ~/.zshrc  # or .bashrc

Usage

# Just clone as usual
git clone git@github.com:you/new-repo.git

# AGENTS.md and CLAUDE.md (symlink) are already there
ls new-repo/
# AGENTS.md  CLAUDE.md -> AGENTS.md

# Works with ghq too
ghq get you/new-repo

How It Works

The script defines thin `git()` and `ghq()` wrapper functions that run after every `git clone` / `ghq get`:

1. Parses arguments to find the target directory
2. Checks if the repo is empty (< 3 items excluding .git)
3. Skips if AGENTS.md already exists
4. Creates AGENTS.md from a built-in template (or custom template)
5. Creates CLAUDE.md as a symlink to AGENTS.md

Customization

Custom template

Set `AGENTS_MD_TEMPLATE` or place a template at `~/.config/agents-md/template.md`:

export AGENTS_MD_TEMPLATE="$HOME/my-agents-template.md"

Empty-repo threshold

The default threshold is 3 items. To change it, modify the `((
