Question

Your application defined a get_weather tool, and Claude responded with a tool_use block containing id 'toolu_01A2b3'. You call your weather API, get the result, and now need to send it back to Claude so it can continue generating its answer. Which field must your tool_result content block include to correctly associate the result with Claude's request?

Accepted Answer

A tool_use_id field set to 'toolu_01A2b3', matching the id from Claude's tool_use block

Answer

The tool's name ('get_weather') as the sole identifier so Claude knows which tool produced the result

Answer

A new randomly generated id that your client creates for tracking the response

Answer

The input JSON schema of the tool repeated in full so Claude can validate the result
