- Agent turns: reasoning, tool calls, subagents and the sources behind an answer
- Run logs that expand to output, from CI jobs and data builds to webhook deliveries
- Checklists of automated checks or setup steps with running, failed and pending states
When not to use
- One short status line per step with no expanding detail or status color: use the Marker component
- Dated events or milestones joined by a connecting line: use the Timeline component
- A complete run console with approvals, log views and an outcome report: use the Agent Activity blocks
