AGR — Skills for AI Agents

AGR — Skills for AI Agents

A package and project manager for AI agent skills. Install, share, and run skills from GitHub with a single command.

!!! note "Migrating from rules, subagents, or slash commands?" Support for rules, subagents, and slash commands has been removed. Most AI coding agents are converging on skills as the standard format, so agr now focuses exclusively on skills. To convert your existing files to skills, run:

```bash
agrx kasperjunge/migrate-to-skills
agrx kasperjunge/migrate-to-skills -p "convert files in ./my-commands"
```

Install

pip install agr

Beta note: Multi-source support is only in the beta release right now. Install agr==0.7.2b1 to use default_source, [[source]], or --source.

Choose Your Path

Install a Skill (persist it)

agr add anthropics/skills/frontend-design

This installs the skill into your tool's skills folder. Use --source <name> to pick a non-default source from agr.toml.

Run a Skill Once (no install)

agrx anthropics/skills/pdf                  # Run once, then clean up
agrx anthropics/skills/pdf -p "Extract tables from report.pdf"
agrx anthropics/skills/pdf -i               # Interactive: run skill, then continue chatting

The -i flag runs the skill first, then starts an interactive session so you can continue the conversation.

Share with Your Team

Dependencies are tracked in agr.toml:

default_source = "github"

dependencies = [
    {handle = "anthropics/skills/frontend-design", type = "skill"},
    {handle = "anthropics/skills/skill-creator", type = "skill"},
]

[[source]]
name = "github"
type = "git"
url = "https://github.com/{owner}/{repo}.git"

Teammates install everything with:

agr sync

Create a Skill

agr init my-skill

Then edit my-skill/SKILL.md. If you want it in this repo, place it under ./skills/ and run agr init to update agr.toml.

Migrate Old Rules or Commands

agrx kasperjunge/migrate-to-skills

Commands (Quick Reference)

Handle Format

agr add user/skill              # From user's "agent-resources" repo
agr add user/repo/skill         # From a different repo
agr add ./path/to/skill         # Local path

If a user's repo is named agent-resources, you can skip the repo name:

agr add kasperjunge/commit                    # From kasperjunge/agent-resources
agr add kasperjunge/agent-resources/commit    # Same thing (explicit)

How Skill Discovery Works

When you run agr add user/repo/skill, agr searches that repo for a skill named skill. It will be found if it exists in:

• resources/skills/{skill}/SKILL.md
• skills/{skill}/SKILL.md
• {skill}/SKILL.md

If two skills have the same name, you'll get an error.

Project Setup

agr init discovers skills in your repo (based on the skills specification) and adds them to agr.toml as local path dependencies. It also detects tools from existing tool folders.

agr init       # Auto-discover skills and create agr.toml
agr init -i    # Guided setup

By default, skills inside tool folders (e.g. .claude/skills/, .codex/skills/, .cursor/skills/, .opencode/skill/, .github/skills/) are ignored to avoid messy configs. To bring them into your repo, run:

agr init --migrate

Example Skills

agr add anthropics/skills/frontend-design    # Build production-grade UIs
agr add anthropics/skills/skill-creator      # Create new skills
agr add anthropics/skills/pdf                # Work with PDF documents
