Subagent Invocation and Context Passing: A Worked Example
In the realm of agentic architecture, designing effective agentic loops and orchestrating multi-agent systems is crucial for autonomous task execution. This article focuses on a practical example of subagent invocation and context passing using the Claude Agent SDK.
Scenario Overview
Imagine a scenario where a customer service application utilizes multiple agents to handle inquiries. The main agent, CoordinatorAgent, is responsible for delegating tasks to subagents based on the nature of the inquiry. Each subagent specializes in different areas such as billing, technical support, and account management.
Step 1: Designing the Agentic Loop
The first step is to create an agentic loop where the CoordinatorAgent listens for incoming requests. When a request is received, it determines the appropriate subagent to handle the task.
Example Code Snippet
CoordinatorAgent listens for requests:
function onRequestReceived(request) { const subagent = determineSubagent(request); invokeSubagent(subagent, request);}Step 2: Invoking the Subagent
Once the appropriate subagent is determined, the next step is to invoke it. This involves passing the necessary context to ensure the subagent has all relevant information to process the request.
Example Code Snippet
Invocation of the subagent:
function invokeSubagent(subagent, request) { const context = createContext(request); subagent.processRequest(context);}Step 3: Context Management
Managing context is vital for the subagent to function effectively. The context includes information such as user details, previous interactions, and the specific inquiry type. This context is passed to the subagent during invocation.
Example Code Snippet
Creating context:
function createContext(request) { return { userId: request.userId, inquiryType: request.type, previousInteractions: fetchPreviousInteractions(request.userId) };Step 4: Subagent Processing
After receiving the context, the subagent processes the request. It can also modify the context if needed, which can later be passed back to the CoordinatorAgent for further actions.
Example Code Snippet
Subagent processing function:
function processRequest(context) { // Handle the request based on context // Modify context if necessary return context;}Step 5: Returning Context to CoordinatorAgent
Finally, once the subagent completes its task, it returns the context back to the CoordinatorAgent. This allows the coordinator to maintain session state and manage any follow-up actions.
Example Code Snippet
Returning context:
function onSubagentComplete(context) { // Handle the completion of the subagent's task // Update session state if necessary}Conclusion
This worked example illustrates the process of subagent invocation and context passing within an agentic architecture using the Claude Agent SDK. By effectively managing context and orchestrating subagents, developers can create robust applications capable of handling complex tasks autonomously.
