T3 Code provides an interface for several coding agents. Its README requires at least one supported provider to be installed and authenticated before use. [1]

## Connect the provider before starting

Follow the provider setup linked from the repository. For Claude Code, the README gives this authentication command: [1]

```bash
claude auth login
```

To try T3 Code without a permanent installation, its documented command is: [1]

```bash
npx t3@latest
```

Start in a project you can safely change. Confirm the selected provider and review the permissions it receives.

## Inspect the work before sharing it

Ask for one small change and read the resulting diff. Run the project's normal checks before committing or pushing. An interface that combines agent work and source control still needs that review.

For access from a phone or another machine, use the repository's remote-access documentation. [1] Check which machine runs the agent and holds its credentials before enabling access. Keep the server and application versions compatible when updating them.
