Which models support the Structured Outputs feature?

This feature is currently supported by Claude 3.5 Sonnet (4.5) and Claude 3.7 Opus (4.1) using the required beta headers.

Can I use JSON outputs and strict tool use in the same request?

Yes, Claude supports hybrid workflows where both JSON output formatting and strict tool validation are used simultaneously for complex operations.

Does this skill provide actual implementation code?

This skill acts as an advisor to determine the best strategy and then delegates the actual schema design and code generation to specialized implementer skills.

What is the difference between JSON Outputs and Strict Tool Use?

JSON Outputs are used when you need Claude's final response to follow a specific JSON schema, while Strict Tool Use ensures that parameters passed to external functions are 100% type-valid.

API開発

Guides developers in implementing Anthropic's structured outputs feature by selecting the optimal mode between JSON responses and strict tool use.

概要

The Structured Outputs Advisor serves as a strategic consultant for developers building high-reliability applications with Claude. It analyzes specific project requirements to determine whether to utilize JSON Output mode for data extraction and API formatting or Strict Tool Use for validated agentic workflows and function calls. By evaluating factors like schema complexity and downstream consumption, the skill ensures 100% schema compliance and provides a clear path to production-ready implementation using the latest Anthropic beta headers and model capabilities.
