List all debug sessions.
Show {limit} debug sessions starting at offset {offset}.
DELETE /debug-sessions/{debugSessionKey} Delete a debug session and its events · delete a specific debug session and all its events #
Ask an LLM
“How do I delete a debug session I no longer need?”
“Does removing a debug session also clear its events?”
Tell an agent destructive · confirm first
Delete debug session {debugSessionKey}.
Remove debug session {debugSessionKey} along with all its events.
GET /debug-sessions/{debugSessionKey}/events Get events from a debug session · get events for a specific debug session #
Ask an LLM
