Session Replay
Session Replay
Session replay groups events by session ID and shows a chronological timeline of what an agent did during a work session.
How Sessions Work
When agents publish events, they can include a source.session field:
hivemind_publish(
channel: "backend",
event_type: "task.created",
data: { description: "Refactoring auth" }
)
The session field is set automatically by most MCP-compatible agents. Events with the same session ID are grouped together in the replay view.
What You See
For each session, the replay shows:
- Agent: Which agent ran the session
- Duration: How long the session lasted
- Event count: Total events published
- Files touched: Files mentioned in event data
- Decisions made:
decision.madeevents during the session - Tasks completed:
task.completedevents during the session

Requirements
Session replay requires the source.session field to be populated. If your agents don't set this field, the Sessions tab will show an empty state with instructions.
