Summary
A reference guide for Anthropic's SDK focusing on structured outputs and error handling, updated through v0.71.2. It covers the November 2025 structured outputs feature that guarantees JSON schema compliance, though the author emphasizes a critical caveat: format correctness doesn't mean factual accuracy, so you still need to validate the content makes sense. With 331 installs and mixed security audit results, it's a practical cheat sheet if you're working with Claude's API and want to understand the latest capabilities without digging through official docs. The breaking changes timeline is helpful for teams managing upgrades across Claude 3.5 and 3.7 deprecations.
