#### Manage agent skills with `gh skill` (Public Preview)

[Agent skills](https://agentskills.io) are portable sets of instructions, scripts, and resources that teach AI coding agents how to perform specific tasks. The new `gh skill` command makes it easy to discover, install, manage, and publish agent skills from GitHub repositories - right from the CLI.

```

# Discover skills
gh skill search copilot

# Preview a skill without installing
gh skill preview github/awesome-copilot documentation-writer

# Install a skill
gh skill install github/awesome-copilot documentation-writer

# Pin to a specific version
gh skill install github/awesome-copilot documentation-writer --pin v1.2.0

# Check installed skills for updates
gh skill update --all

# Validate and publish your own skills
gh skill publish --dry-run
```

Skills are automatically installed to the correct directory for your agent host. `gh skill` supports GitHub Copilot, Claude Code, Cursor, Codex, Gemini CLI, and Antigravity. Target a specific agent and scope with `--agent` and `--scope` flags.

`gh skill publish` validates skills against the [Agent Skills specification](https://agentskills.io/specification) and checks remote settings like tag protection and immutable releases to improve supply chain security.

Read the full announcement on the [GitHub Blog](https://github.blog/changelog/2026-04-16-manage-agent-skills-with-github-cli/).

`gh skill` is launching in public preview and is subject to change without notice.

#### Official extension suggestions

When you run a command that matches a known official extension that isn't installed (e.g. `gh stack`), the CLI now offers to install it instead of showing a generic "unknown command" error.

This feature is available for [github/gh-aw](https://github.com/github/gh-aw) and [github/gh-stack](https://github.com/github/gh-stack).

When possible, you'll be prompted to install immediately. When prompting isn't possible, the CLI prints the `gh extension install` command to run.

#### `gh extension install` no longer requires authentication

`gh extension install` previously required a valid auth token even though it only needs to download a public release asset. The auth check has been removed, so you can install extensions without being logged in.
