agr
The package manager for AI agents.
Install, share, and sync agent resources across Claude Code, Cursor, Codex, OpenCode, Copilot, and Antigravity β 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 β 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 β 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 β 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 β 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.
