Agent Resources - The package manager for AI agents. Built for teams.

agr

The package manager for AI agents.

Install, share, and sync agent resources across Claude Code, Cursor, Codex, OpenCode, Copilot, and Antigravity — built for teams practicing Agentic Engineering.

---

Getting Started

Install the CLI:

uv tool install agr

Install your first skill:

agr add anthropics/skills/frontend-design

Then invoke it in your AI tool:

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

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

---

Run a skill without installing

agrx downloads a skill, runs it with your tool's CLI, and cleans up. Nothing is saved to your project:

agrx anthropics/skills/pdf -p "Extract tables from report.pdf"
agrx anthropics/skills/skill-creator -i   # Interactive: skill + chat

---

Built for teams

agr is built for teams practicing Agentic Engineering — where AI agents are first-class members of your development workflow. Share a consistent set of agent resources across every developer and every AI tool on your team.

Dependencies are tracked in agr.toml — commit it, and teammates install everything with one command:

dependencies = [
    {handle = "anthropics/skills/frontend-design", type = "skill"},
    {handle = "anthropics/skills/pdf", type = "skill"},
    {handle = "your-team/agent-resources/dev-workflow", type = "package"},
]

agr sync   # Like npm install, but for AI agents

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

---

Create and share

agr init my-skill                # Scaffold a new skill
# Edit my-skill/SKILL.md with your instructions
agr add ./my-skill               # Test locally
# Push to GitHub, then others can:
agr add your-username/my-skill

---

Python SDK

Use agr as a library to load, discover, and cache skills programmatically:

from agr import Skill, list_skills, skill_info

skill = Skill.from_git("anthropics/skills/code-review")
print(skill.prompt)   # SKILL.md contents
print(skill.files)    # Files in the skill directory

for info in list_skills("anthropics/skills"):
    details = skill_info(info.handle)
    print(f"{details.handle}: {details.description}")

See the SDK documentation for cache management, error handling, and the full API.
