## Summary [#summary]

**Claw** is an autonomous assistant that operates a sandboxed workspace to finish
multi-step tasks. It reads and writes files, runs shell commands scoped to a
workspace directory, and follows reusable skills. Reach for it as a base for
coding assistants, repo automation, or any agent that needs a real filesystem.

## Customization [#customization]

* **Harden the sandbox.** Run `run_shell` inside a container or jail; the path
  guard only constrains file paths, not arbitrary commands.
* **Add web browsing.** Pair with the [Browser Agent](/docs/agents/mastra/browser-agent)
  tools for tasks that need the web.
* **Add skills.** Drop more `SKILL.md` procedures under `skills/`.
* **Swap the model.** Edit `config.ts`.
