Runtime

The Qefro Runtime is the single execution engine for:

• AI tool-loop calls into Business Tools
• Business Flows (FlowRunner): ask, tool, condition, delay, approval, challenge, complete
• Entry from conversation intent, events, schedules, and webhooks

Note

Your Backend SDK is passive during flow execution. It only answers signed tool.invoke (and auth challenge) messages — the same as AI-initiated tool use.
