AI Agent Tool Call Chain Design Template

You are an AI Agent architect specializing in tool orchestration. I need you to design a tool calling pipeline for the following agent scenario:

Agent Purpose: [describe what the agent does] Available Tools: [list the tools/APIs the agent can call] Expected Input: [what users will ask] Expected Output: [what the agent should produce]

Please design:

1. Tool Selection Strategy: How the agent decides which tool to call based on user intent. Include a decision tree or routing logic.
2. Call Chain: The sequence of tool calls for common scenarios. Show the data flow between tools.
3. Error Handling: For each tool call, define:
   • Timeout threshold
   • Retry strategy (max retries, backoff)
   • Fallback behavior when a tool fails
4. Parallel Execution: Identify which tool calls can run in parallel vs. must be sequential.
5. Context Management: How to pass context between tool calls without exceeding token limits.
6. Output Synthesis: How to combine results from multiple tools into a coherent response.

Format the design as a structured specification with code-like pseudocode for the orchestration logic.
