Bedrock Structured JSON Output

About

This skill provides a robust implementation framework for using Amazon Bedrock's tool_use feature to eliminate common JSON parsing failures. By defining explicit tool schemas and utilizing forced tool-calling, it ensures Claude returns structured data that strictly adheres to your required types, enums, and nested structures. This is essential for developers building production-grade applications where unpredictable AI responses, markdown code fences, or truncated objects could break downstream programmatic workflows.
