## What are Agent Skills?

Agent skills are reusable instruction sets that extend your coding agent's capabilities. They're defined in `SKILL.md`
files with YAML frontmatter containing a `name` and `description`.

Skills let agents perform specialized tasks like:

- Generating release notes from git history
- Creating PRs following your team's conventions
- Integrating with external tools (Linear, Notion, etc.)

Discover skills at **[skills.sh](https://skills.sh)**

<!-- supported-agents:end -->

> [!NOTE]
> **Kiro CLI users:** After installing skills, manually add them to your custom agent's `resources` in
> `.kiro/agents/<agent>.json`:
>
> ```json
> {
>   "resources": ["skill://.kiro/skills/**/SKILL.md"]
> }
> ```

The CLI automatically detects which coding agents you have installed. If none are detected, you'll be prompted to select
which agents to install to.

## Creating Skills

Skills are directories containing a `SKILL.md` file with YAML frontmatter:

```markdown
---
name: my-skill
description: What this skill does and when to use it
---

# My Skill

Instructions for the agent to follow when this skill is activated.

## When to Use

Describe the scenarios where this skill should be used.

## Steps

1. First, do this
2. Then, do that
```

### Required Fields

- `name`: Unique identifier (lowercase, hyphens allowed)
- `description`: Brief explanation of what the skill does

### Optional Fields

- `metadata.internal`: Set to `true` to hide the skill from normal discovery. Internal skills are only visible and
  installable when `INSTALL_INTERNAL_SKILLS=1` is set. Useful for work-in-progress skills or skills meant only for
  internal tooling.

```markdown
---
name: my-internal-skill
description: An internal skill not shown by default
metadata:
  internal: true
---
```

### Skill Discovery

The CLI searches for skills in these locations within a repository:

<!-- skill-discovery:start -->
- Root directory (if it contains `SKILL.md`)
- `skills/`
- `skills/.curated/`
- `skills/.experimental/`
- `skills/.system/`
- `.agents/skills/`
- `.agent/skills/`
- `.augment/rules/`
- `.claude/skills/`
- `./skills/`
- `.cline/skills/`
- `.codebuddy/skills/`
- `.codex/skills/`
- `.commandcode/skills/`
- `.continue/skills/`
- `.crush/skills/`
- `.cursor/skills/`
- `.factory/skills/`
- `.gemini/skills/`
- `.github/skills/`
- `.goose/skills/`
- `.junie/skills/`
- `.iflow/skills/`
- `.kilocode/skills/`
- `.kiro/skills/`
- `.kode/skills/`
- `.mcpjam/skills/`
- `.vibe/skills/`
- `.mux/skills/`
- `.opencode/skills/`
- `.openclaude/skills/`
- `.openhands/skills/`
- `.pi/skills/`
- `.qoder/skills/`
- `.qwen/skills/`
- `.roo/skills/`
- `.trae/skills/`
- `.windsurf/skills/`
- `.zencoder/skills/`
- `.neovate/skills/`
- `.pochi/skills/`
- `.adal/skills/`
<!-- skill-discovery:end -->

If no skills are found in standard locations, a recursive search is performed.

## Compatibility

Skills are generally compatible across agents since they follow a
shared [Agent Skills specification](https://agentskills.io). However, some features may be agent-specific:

| Feature         | OpenCode | OpenHands | Claude Code | Cline | CodeBuddy | Codex | Command Code | Kiro CLI | Cursor | Antigravity | Roo Code | Github Copilot | Amp | Clawdbot | Neovate | Pi  | Qoder | Zencoder |
| --------------- | -------- | --------- | ----------- | ----- | --------- | ----- | ------------ | -------- | ------ | ----------- | -------- | -------------- | --- | -------- | ------- | --- | ----- | -------- |

| Hooks           | No       | No        | Yes         | Yes   | No        | No    | No           | No       | No     | No          | No       | No             | No  | No       | No      | No  | No    | No       |

## Troubleshooting

### "No skills found"

Ensure the repository contains valid `SKILL.md` files with both `name` and `description` in the frontmatter.

### Skill not loading in agent

- Verify the skill was installed to the correct path
- Check the agent's documentation for skill loading requirements
- Ensure the `SKILL.md` frontmatter is valid YAML

### Permission errors

Ensure you have write access to the target directory.

## Environment Variables

| Variable                  | Description                                                                |
| ------------------------- | -------------------------------------------------------------------------- |
| `INSTALL_INTERNAL_SKILLS` | Set to `1` or `true` to show and install skills marked as `internal: true` |
| `DISABLE_TELEMETRY`       | Set to disable anonymous usage telemetry                                   |
| `DO_NOT_TRACK`            | Alternative way to disable telemetry                                       |

```bash
# Install internal skills
INSTALL_INTERNAL_SKILLS=1 npx skills add vercel-labs/agent-skills --list
```

## Telemetry

This CLI collects anonymous usage data to help improve the tool. No personal information is collected.

Telemetry is automatically disabled in CI environments.
