Discovering More Skills

Search GitHub

Any GitHub repository with a SKILL.md file can be installed as a handle:

List skills in a repository

Use the Python SDK to list all skills in any repo:

from agr import list_skills, skill_info

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

Note

list_skills() discovers skills without downloading each SKILL.md, so description is None. Use skill_info() to fetch the description for a specific skill.

Or check a repo manually — agr looks for any directory containing a SKILL.md file.

Try before you install

Use agrx to run any skill without adding it to your project:

agrx anthropics/skills/webapp-testing
agrx anthropics/skills/pdf -i   # Interactive: continue chatting after the skill runs

Share Your Own Skills

1. Create a skill

agr init my-skill

Edit the generated my-skill/SKILL.md with your instructions. See agr init for all options.

2. Push to GitHub

Push your skill to a GitHub repository. The recommended structure is a repo named skills with one directory per skill:

your-username/skills/
├── my-skill/
│   └── SKILL.md
└── another-skill/
    └── SKILL.md

Others can then install with:

agr add your-username/my-skill

3. List it here

Open an issue at github.com/kasperjunge/agent-resources to get your skill added to this directory. For team-wide sharing, you can also use a private repository with agr.toml.

See Creating Skills for a full guide on writing effective skills.
