Agent Nexus workforce model
Agents are digital employees. Sub-agents are specialist employees. Crews are specialist teams. Workbenches are their tools, checklists, playbooks, and operating dashboards. Validators are independent reviewers. Humans remain final approvers for high-risk decisions.
Agent
Owns a business function
Sub-Agent
Handles a specialist track
Crew
Executes as a specialist team
Workbench
Provides tools and playbooks
Validator
Checks quality and risk
Approval
Keeps humans accountable
Agent → Sub-Agent → Crew → Workbench
A workbench is not an agent. It is the execution environment used by a sub-agent and its crew.
Coordinator
Selects workflow and routing
Primary Agent
Owns business outcome
Sub-Agent
Handles specialist track
Crew
Executes as expert team
Workbench
Tools, playbooks, checklists
Validators
Independent quality gates

Cisco Recommendation
Finance / Legal / Operations / MD Approval
A workbench is not an agent. It is the workspace used by a sub-agent or crew to complete specialist work with tools, checklists, validators, evidence and approval gates.

Used by
Application, AI/Data, Security Sub-Agents + IT-Security Review Crew
Used for
Application architecture, API integration, RAG, model selection, guardrails, evaluation, compliance, security review.
Primary outputs

Human validation required for security risk acceptance, data privacy, legal compliance, and production approvals.
Open Application / AI / Security Workbench How they fit into the enterprise workflow
- LangGraph Coordinator selects the relevant primary agent and workflow.
- The primary agent delegates specialist work to sub-agents.
- Sub-agents invoke crews when deeper domain execution is required.
- Crews use workbenches for tools, checklists, validators and evidence.
- Validators independently verify outputs before approval or final synthesis.
Design principle
Use the minimum required sub-agents and crews for a task. Cisco runs only when networking is in scope. Cloud, Application, AI/Data and Security run only when their domain is required. IT-Security Review runs independently when customer data, production systems or compliance risk is involved.
