In simple English
AI coding assistants work better when they have access to specialised instructions and reference documents. This tool lets you download those skill packs from GitHub or local folders into any coding assistant. It uses the same file format as Claude Code. You do not need to install the whole Claude system to use them. It runs from your command line and costs nothing.
What it is
A command-line tool written in TypeScript that manages SKILL.md files for AI coding agents. It generates an XML index in an AGENTS.md file so different AI coding assistants can discover and load instructions on demand.
What it is good for
Developers who use multiple AI coding assistants and want to share the same custom prompt skills, toolkits, and reference workflows across all of them.
Summary (Key Points)from the README
Key features
- Claude Code format: Writes the same `<available_skills>` XML into `AGENTS.md`, so agents that read that file can use Claude Code skills.
- Install sources: Installs from the Anthropic marketplace (`anthropics/skills`), any GitHub repo, a local path, or a private git repo.
- On-demand loading: Agents run `npx openskills read <name>` to load a skill's instructions only when a task needs it, which keeps context small.
- Sync command: `sync` regenerates `AGENTS.md`, with `-y` for CI and `-o` for a custom output file.
- Update and remove: `update` refreshes git-installed skills, either all of them or a comma-separated list. `manage` removes skills interactively and `remove` deletes one by name.
- Install scope: Skills install per project by default. `--global` uses `~/.claude/skills`, and `--universal` uses `.agent/skills/`.
- Four-level priority order: Project `.agent/skills/` wins over home `.agent/skills/`, which wins over project `.claude/skills/`, which wins over home `.claude/skills/`.
- Skill layout: A skill needs only a `SKILL.md` file, and may add `references/`, `scripts/` and `assets/` folders.
Ways to install
| Platform or method | What it needs | Effort |
|---|---|---|
| Anthropic marketplace (`anthropics/skills`) | Node.js 20.6+, Git | One `npx` command |
| Any public GitHub repo | Node.js 20.6+, Git | One `npx` command |
| Local path | Node.js 20.6+, the skill folder on disk | One `npx` command |
| Private git repo | Node.js 20.6+, Git, access to the private repo | One `npx` command plus repo access |
Important
- Requirements: Node.js 20.6 or newer and Git are needed. Git is used to clone repositories.
- Shell access for agents: Loading a skill means the agent must run `npx openskills read` in a shell. An agent without shell access cannot use skills this way.
- Multi-agent conflicts: If Claude Code and other agents share one `AGENTS.md`, use `--universal` to avoid conflicts with Claude's plugin marketplace.
- Updates need a recorded source: Skills installed before update tracking existed must be reinstalled once before `update` works on them.
- Not affiliated with Anthropic: The project implements Anthropic's Agent Skills specification but is not made or endorsed by Anthropic. Claude and Claude Code are Anthropic trademarks.
Written by an AI model from the project’s README; not part of the review, and it can be wrong.
- Compatible with the Claude Code skill format and marketplace.
- Works with Cursor, Windsurf, Aider, Codex, and other agents.
- Keeps context windows clean by loading skills only when requested.
- Requires Node.js version 20.6 or newer installed on your machine.
- Relies on Git being installed to clone skill repositories.
- Custom licence terms apply rather than a standard open-source grant.
