agr

The package manager for AI agents.

Share AI agent skills across your team like code packages — from any Git repo, into Claude Code, Cursor, Codex, and more.

---

Getting started

Install the CLI:

uv tool install agr

Install your first skill:

agr add anthropics/skills/pdf

Handles follow the pattern owner/repo/skill — pointing to a directory inside a GitHub repo. anthropics/skills/pdf means the pdf/ directory inside github.com/anthropics/skills.

Then invoke it in your AI tool:

Tool	Invoke with
Claude Code	/pdf
Cursor	/pdf
OpenAI Codex	$pdf
OpenCode	pdf
GitHub Copilot	/pdf
Antigravity	(via IDE)

No setup required — agr add auto-creates agr.toml and detects which tools you use.

Built for teams

agr is opinionated: skill directories (.claude/skills/, .cursor/skills/, …) are build artifacts — like .venv/ or node_modules/. Add them to .gitignore. Commit agr.toml and agr.lock instead. agr sync rebuilds the environment from the manifest on every machine.

tools = ["claude", "cursor"]

dependencies = [
    {handle = "anthropics/skills/pdf", type = "skill"},
    {handle = "anthropics/skills/frontend-design", type = "skill"},
]

agr sync   # Like npm install, but for AI agents

New teammate? agr sync and they're productive on day one — same skills, same standards, every tool.

---

Keep skills up to date

agr upgrade            # all skills
agr upgrade pdf        # one skill
