# Stream

> Follow agent actions and explore sandbox files while a job runs.

See what the agent is doing and inspect its work while a job runs:

1. **Stream agent logs.** Follow agent actions, commands, and results in the
   **Trajectory** tab as new steps arrive.
2. **Watch the agent's directory.** Open the **Stream** tab to browse sandbox
   files and generated artifacts in real time. It connects automatically after sandbox is ready.

Add `--stream` to your run. Currently supports Claude Code and Codex on Daytona, Modal, local Docker:

```bash theme={"system"}
harbor run -t terminal-bench/build-cython-ext \
  -a claude-code -m anthropic/claude-sonnet-5 -e docker --stream
```

In another terminal:

```bash theme={"system"}
harbor view jobs
```

Run the browser and viewer on the same machine.
For Daytona, make credentials available to both Harbor **and the viewer**.

Add `--no-delete` to keep the sandbox available after the run. Don't forget to delete later.
