Which models does this skill use by default?

This skill defaults to Claude Opus 4.6 (model ID: claude-opus-4-6) to provide the highest reasoning capabilities and supports adaptive thinking out of the box.

What programming languages are supported?

It includes specific documentation and code examples for Python, TypeScript/JavaScript, Java, Go, Ruby, C#, PHP, and raw cURL/HTTP requests.

Does it support the Anthropic Agent SDK?

Yes, it provides a decision tree to help you determine when the Agent SDK is appropriate, specifically for tasks requiring web browsing, file access, or shell commands.

How does it handle extended thinking or reasoning?

It implements adaptive thinking (thinking: {type: 'adaptive'}) which allows Claude to dynamically determine the necessary reasoning depth without needing deprecated token budgets.

Does this skill help with structured outputs?

Yes, it provides patterns for constraining response formats using output_config and client.messages.parse() for schema validation.
