List all flow definitions for tenant 'main-prod'.

I've retrieved the workflows for 'main-prod'. You have 3 active flows: 'payment-process', 'send-welcome-email', and 'data-sync'. Which one would you like to inspect?

Execute the 'data-sync' flow with input { "source": "crm" }.

Executing 'data-sync'... The flow completed successfully. The output indicates that 150 records were synchronized from the CRM source. Do you need the full execution trace?

Show me the step-by-step execution trace for ID 'exec_789xyz' in tenant 'main-prod'.

Fetching trace for 'exec_789xyz'... The execution had 4 steps: 1. Auth (Success), 2. Fetch Data (Success), 3. Transform (Success), 4. Load (Success). Total duration was 450ms.

Yes. Use the `execute_flow` tool with the flow name and input data. It performs a real-time sync execution and returns the response directly to the agent.
