Steps Create a Bedrock Runtime client: client = boto3.client('bedrock-runtime', region_name='us-east-1') Build a toolConfig dict defining your tools with name, description, and inputSchema in JSON Schema format Call client.converse(modelId=<model_id>, messages=messages, toolConfig=toolConfig) — the Converse API works uniformly across supported models If the response stopReason is 'tool_use', extract the tool name and input from the response content block and execute the tool locally Append the tool result as a new message with role 'user' and content type 'toolResult', then call converse() again AWS recommends Converse over InvokeModel for multi-turn and tool-use workflows because it normalizes the interface across all Bedrock models Known gotchas Not all Bedrock models support tool use via Converse — check the model's supported features in the Bedrock console before building tool workflows The toolConfig is separate from the messages array — tool definitions go in toolConfig, not in the system prompt For streaming responses use converse_stream() — it returns an event stream, not a single response dict
