Shows patterns for handling multiple tool calls in a single turn, and introduces a “batch tool” wrapper idea.

• Upstream notebook: tool_use/parallel_tools.ipynb

What to focus on

• Iterating response.content and handling multiple tool_use blocks
• Returning tool_result with correct tool_use_id
• Batch tool pattern: bundling multiple invocations to reduce turns
