# Appendix: optional tools

Suggestions, not requirements: the gate, the docs check and the rules in [Working on it](../dev/contributing.md) do not depend on any of them.

| Tool | Use it for |
|---|---|
| [Local review with git-review](git-review.md) | Reviewing an agent's branch as one staged diff and approving it as one commit, without a pull request |
| [GPUI Kit skills](gpui-kit-skills.md) | Giving Claude GPUI Kit's Coding and Design Guides while it changes the console's UI |
