Live mode
Live mode is the default. One conversation, one chat window, one or more agents working in real time. Use it when you want to stay in the loop and intervene quickly.
The trace panel
While the chat streams, the right-hand panel shows every step the agents are taking. Each row is colored by phase: amber = running, emerald = done, rose = failed, slate = blocked. Click a row to expand the tool input and output. Click a tool name to copy a re-runnable snippet:
# from the trace panel "Copy as cURL"
curl -X POST https://loom.mingllm.com/api/jobs/<id>/rerun-step \
-H "Authorization: Bearer $LOOM_API_KEY" \
-d '{"step_id": "stp_8a3..."}'Branching
When an agent makes a decision you want to override, click the three-dot menu on its step in the trace panel and pick Branch from here. Loom snapshots the conversation state, lets you edit the brief, and re-fires from that step. The original branch stays available — you can compare artifacts in the Artifacts panel by holding shift and clicking two files.
When to switch to Factory
Live mode is great for under-five-minute briefs. If the planner estimates more than 30 steps or a cost over $1, Loom suggests kicking it to Factory mode instead. You can also set auto_factory_threshold in Settings — any brief whose estimate exceeds your threshold is routed automatically.
