# Skills

> Install reusable instructions that help coding agents work with SuperDoc

SuperDoc skills are reusable instruction bundles for coding agents. They provide task-specific guidance, examples, and verification steps for working with the SDK.

## Custom actions

The `superdoc-custom-actions` skill helps Claude Code and Codex define, wire, and test custom LLM actions.

```bash theme={null}
npx skills add superdoc-dev/superdoc/packages/sdk/skills/superdoc-custom-actions --copy
```

See [Custom actions](/ai/agents/custom-actions) for the SDK workflow, execution tiers, and installation details.
