AI Agent Architecture
AI agents are most useful when they are designed as focused business components. Each agent should have a clear role, controlled access to tools and data, logging, guardrails, and a human approval path when decisions affect customers, money, operations, or compliance.
What AI Agents Do
AI agents can classify requests, retrieve information, plan work, execute workflows, review compliance, process documents, create notifications, analyze business data, and coordinate multiple specialized systems. The best architecture is usually not one large chatbot. It is a controlled group of agents with narrow responsibilities and clear handoffs.

Scores options, compares risks, explains reasoning, and recommends the next best action while preserving human approval.
Best-fit use cases

Handles common customer questions, uses account context when allowed, and escalates complex or sensitive issues.
Best-fit use cases
Support chat, service status, appointment questions, account help, internal help desk.
Plans software changes, edits code, runs tests, updates documentation, and prepares changes for review.
Best-fit use cases
App rescue, mobile development, website changes, bug fixes, branch-based delivery, changelog updates.
Combines an orchestrator, specialized agents, shared tools, governance, logs, and human approvals into a complete AI business system.
Best-fit use cases
Enterprise AI workflows, insurance claims, pension systems, field service, secure customer operations.
Recommended Architecture
For most business systems, the safest and most maintainable approach is a multi-agent architecture with one orchestrator, several narrow-purpose agents, limited tool access, database permissions by role, audit logging, and human approval for sensitive actions.
Guardrails
AI agents should be designed with least-privilege access, clear logs, safe fallbacks, approval queues, and data boundaries. Any system that changes appointments, sends messages, updates records, reviews claims, or handles private information should be built with human oversight and auditable actions.
