When should I use the Agent SDK vs. the standard API?

Use the Agent SDK when you need built-in file, web, or terminal tools out of the box. Use the standard Claude API for single LLM calls, pipelines, or when you want full control over your own tools.

What is the 'Adaptive Thinking' feature?

It uses the thinking: {type: 'adaptive'} configuration, allowing Claude to dynamically decide the depth of reasoning required for a task without needing manual token budgets.

Which model does this skill default to?

This skill defaults to Claude Opus 4.6 (claude-opus-4-6) to ensure the highest reasoning capabilities and performance for your application.

Does this support languages other than Python and TypeScript?

Yes, it provides specific guidance and documentation for Java, Go, Ruby, C#, PHP, and raw cURL/HTTP requests.
