- Live: open a running session to see what the agent sees, step by step, while it works. Useful when you’re prompt-tuning, debugging an unexpected detour, or just confirming the run hasn’t stalled.
- Replay: after the session terminates, scrub through the full trajectory (every observation, action, and message) to audit what happened.
events stream your code does, so anything the API exposes is reflected in the UI.
