The decision in plain English
Where this fits in your work
The Grok surface for changing a software project, rather than discussing code in chat.
- Consider it when
- Consider it for repository work with file edits, terminal checks and separate subagents for investigation or implementation.
- The limit to keep in mind
- Review permission and sandbox settings before delegating. Subagents do not replace checking the combined patch and behaviour.
- A first task to try
- On a branch, ask it to explain the repo, propose one small change and a validation plan. Inspect the diff and run the checks before release.
Compare Codex using the same repository task, permissions and acceptance checks.
See Codex →Agent Watch editorial guidance, reviewed . Based on the documented capabilities below; this is a suggested starting task, not a published hands-on test or a performance ranking.
Access, permissions and controls

- Can it open and edit your files?
- Reads and edits project files; runs terminal commands.
- What it can connect to
- MCP servers, skills, plugins, hooks and AGENTS.md; independent subagent sessions.
- Can it keep working while you're away?
- Background tasks and headless scripting; unattended schedule entitlement not confirmed.
- Controls for your organisation
- Ask permission mode by default; configurable approval modes and separate filesystem/network sandbox.
