What are structured outputs in the Claude Agent SDK?

Structured outputs use JSON schema validation to guarantee that Claude's responses match a specific format, ensuring type safety and preventing parsing errors in your application.

Does it support the 1M token context window?

Yes, the skill includes instructions for enabling the context-1m-2025-08-07 beta header within the query options to handle massive codebases.

How does the skill handle subagent resource leaks?

It provides a documented workaround using the 'Stop' hook to manually clean up spawned subagent processes, addressing a known issue where subagents may otherwise persist.

Can this skill help with MCP server configuration?

Yes, it provides implementation patterns for connecting both in-process and external MCP servers via stdio or HTTP, including proper tool naming conventions.

How do I use the SDK hook system?

The SDK provides 12 hook events like PreToolUse and SessionStart. You can define async functions in your query options to intercept, validate, or log events during the agent's execution.
