# Built-in tool catalog

Workspace built-ins can include file, shell, browser, and other Runtime capabilities. The live catalog is the authority; a fixed documentation list would become stale.

*Studio interface in English. Sample data.*

## Review what is available

1. Open `Studio` → `Tools` after the workspace finishes loading.
2. Search for the action you need rather than assuming a tool ID.
3. Check the source tag to distinguish workspace, MCP, and connected-app tools.
4. Check whether the tool is tagged `write` or `execute`.
5. Copy the tool ID and assign it only to the agent that needs it.

## Expected result

The agent’s capability list uses an ID that exists in the current Runtime catalog. A tool appearing in the catalog does not automatically authorize it for every agent or task.
