Building practical AI systems often requires moving beyond a single, monolithic agent. As workflows grow in complexity, a single agent frequently struggles with context limits, tool selection errors, and state management.
Multi-agent orchestration provides a structural solution by delegating tasks to specialized agents. Architects must decide between inline and connected patterns to balance system modularity with governance requirements.
In short
- •
Inline agents act as subroutines within a main agent, sharing context directly to handle specific, reusable tasks.
- •
Connected agents operate as independent entities with their own tools and knowledge, requiring explicit handoff logic and governance.
- •
Choose inline agents for simple, high-frequency tasks; use connected agents for domain-specific operations that require distinct security or audit controls.
Implementing Inline Agents
Inline agents function as internal topics or subroutines. They are ideal for modularizing a main agent's logic without introducing the overhead of separate orchestration layers.
Because they share the parent agent's context, data passing is straightforward. However, this tight coupling means you must keep each inline agent focused on a single responsibility to prevent the parent agent from losing track of the primary goal.
Governing Connected Agents
Connected agents are autonomous units with their own orchestration, tools, and knowledge bases. The parent agent delegates tasks to these specialized agents, such as handing off a pricing query to a dedicated Sales agent.
This pattern enables domain separation and bypasses plan limits, but it introduces a governance challenge. You must define clear handoff criteria in the parent orchestrator. Always describe the connected agent's purpose explicitly in the parent configuration to ensure the orchestrator routes requests to the correct domain.
