A package manager for AI agent skills.
Install, share, and sync skills across Claude Code, Cursor, Codex, OpenCode, Copilot, and Antigravity — with a single command.
Install the CLI:
uv tool install agrInstall your first skill:
agr add anthropics/skills/frontend-designThen 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.
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 + chatDependencies 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"},
]agr sync # Like npm install, but for agent skillsagr 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-skillUse 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.
