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.
