agentsmd adds templating and local .agentsmd preferences to AGENTS.md while keeping the tracked source clean.

Features

• 🧾 Extend AGENTS.md – agentsmd make regenerates AGENTS.md with templates and appends local .agentsmd preferences onto the committed snapshot.
• 🧩 Reusable Templates – Place {{ name }} tokens in AGENTS.md or .agentsmd to pull snippets from ~/.agentsmd/templates/<name>[.md], sharing guidance across projects.
• 🔄 Automate the Refresh – agentsmd enable hooks Git so AGENTS.md regenerates on pulls/checkouts and silently ignores your local rendered copy; agentsmd disable rolls back the Git hooks.
• 🧰 Local Install Only – Everything the CLI writes stays in your working tree — no global state or remote services required.

🚀 Quick Tour

# 1. Install
npm install -g @adiasg/agentsmd

# 2. Drop reusable templates into your home library
mkdir -p ~/.agentsmd/templates
echo "Never run npm run dev yourself." > ~/.agentsmd/templates/nextjs.md
# Refer to this template in AGENTS.md or .agentsmd with {{ nextjs }}
echo "{{ nextjs }}" > .agentsmd

# 3. Place your personal overlay (kept local)
echo "Don't hardcode constants - instead place them in a constants.ts file." >> .agentsmd

# 4. Render templates and append .agentsmd to AGENTS.md
agentsmd make

# 5. (Optional) Git automation for regeneration & ignoring file
agentsmd enable
agentsmd status
agentsmd disable

🧩 Templating Quick Start

Keep the shared AGENTS.md focused on repository guidelines while layering your personal preferences in .agentsmd. Anywhere you place {{ name }} inside the file, agentsmd make will inline content from your home template library at ~/.agentsmd/templates/<name>.
For each location the lookup checks both <name> and <name>.md, so you can opt in to the Markdown suffix without breaking existing snippets.

Note: Rendering templates requires Python 3 to be available as python3 or python.

Example:

### ~/.agentsmd/templates/nextjs.md

- Never run `npm run dev`.

### .agentsmd

### Developer Preferences

- Use orange hues for the accent colors.
{{ nextjs }}

agentsmd make

The resulting AGENTS.md:

<Orignial AGENTS.md contents>

### Developer Preferences

- Use orange hues for the accent colors.
- Never run `npm run dev`.

🧰 CLI Reference

| Command | What it does | |---------|--------------| | agentsmd make | Rebuilds AGENTS.md from the last committed version plus your .agentsmd preferences and templates. | | agentsmd enable | Enables local Git automation for regenerating file on pull/checkout. Installs hooks, merge driver, git rebuild-agents alias, and marks AGENTS.md assume-unchanged. | | agentsmd disable | Removes all installed local Git automation, restores backed up hooks/config. | | agentsmd status | Prints installation status. | | agentsmd --version | Shows the version. |

Run agentsmd help <command> for detailed usage text.

🧱 What agentsmd enable Installs

• Hooks – Managed pre-commit, post-merge, and post-checkout scripts that call agentsmd make when appropriate. Original hooks are saved as <hook>.agentsmd.bak.
• Merge driver – Adds merge=agentsmd to .git/info/attributes so merge conflicts prefer the remote AGENTS.md.
• Git alias – git rebuild-agents points back to the CLI for quick rebuilds.
• Assume unchanged – AGENTS.md is kept out of git status noise but remains editable locally.
• State directory – .git/agentsmd-state/ tracks backups and ownership markers, enabling clean disable flows.

Disable removes each artifact and puts your repo back exactly as it was.

🛠 Contributing

We welcome pull requests! Before opening one:

• Ensure new behaviour is covered by tests where practical.
• Run npm run lint and npm run test.
• Update documentation (README.md, docs/PRD.md, and relevant assets) to match your changes.

.devcontainer/ has an environment with the required tooling (Node LTS, shellcheck, shfmt, bats).

❓ Troubleshooting

• "fatal: not a git repository" – Run commands inside a clone; automation never touches directories without .git.
• AGENTS.md still showing in git status – Ensure the file is tracked; otherwise git update-index --assume-unchanged cannot be set.
• HEAD missing or AGENTS.md untracked – agentsmd make falls back to the working-tree AGENTS.md at the repo root before reapplying preferences.
• Status: DISABLED with missing components – Run agentsmd enable to reinstall; it is safe to re-run and will restore missing pieces.
• Missing template referenced – The token is left as {{ name }} and a warning is printed; fix files in ~/.agentsmd/templates/.
