Which model does the Claude API skill use by default?

The skill defaults to Claude Opus 4.6 (claude-opus-4-6) to ensure the highest quality reasoning and performance for development tasks.

How does the skill handle tool use?

It provides guidance on both user-defined tools (via decorators or Zod schemas) and server-side tools, including the use of SDK tool runners for automated loops.

Does this skill support multiple programming languages?

Yes, it features automatic language detection for Python, TypeScript, Java, Go, Ruby, C#, and PHP, providing language-specific documentation and snippets.

What is Adaptive Thinking in the Claude API?

Adaptive thinking allows Claude to dynamically decide when and how much to reason for a task, replacing the deprecated fixed token budget system.

When should I use the Agent SDK instead of the standard Claude API?

Use the Agent SDK when your application needs built-in file/web/terminal access, permissions, and MCP support out of the box for agentic behavior.
