Architecture Control Center

The full layered architecture of the agentic enterprise.

Enterprise architecture: LangGraph manages the company-level workflow. CrewAI manages specialist department teams. Sub-agents act like skilled employees inside each department. Validators act like independent reviewers. Human approvers remain responsible for final high-risk decisions.

How layers connect

  1. UI sends a request to LangGraph orchestration.
  2. LangGraph classifies, plans, and selects the crews.
  3. CrewAI crews execute with their sub-agents and tools.
  4. Validators independently check every output.
  5. Approval Router escalates to humans when required.
  6. Final Synthesizer returns a consolidated response, audit logged.

Production-grade controls

  • • Tool & permission sandboxing per agent / crew
  • • Confidence + risk thresholds enforced by validators
  • • Independent rework loops back to source crew
  • • All decisions auditable end-to-end
  • • Human-in-the-loop on all commercial / security commitments
