Can I use prompt caching on AWS Bedrock?

Prompt caching is primarily supported through the direct Anthropic API for the Claude 4 family. As of late 2025, Bedrock support for caching is limited to specific older versions like Claude 3.7 Sonnet.

How does Prompt Caching reduce API costs?

By using the cache_control parameter on large context blocks, you can save up to 90% on input tokens for repeated queries, provided the cached content meets the minimum token requirements for the model.

How do I handle errors in streaming (SSE) responses?

Unlike standard HTTP errors, SSE errors can occur after a 200 OK response. This skill teaches you to implement stream-level error listeners to catch mid-stream failures gracefully.

What are Structured Outputs in the Claude API?

Structured outputs guarantee that Claude's responses strictly adhere to your provided JSON schema, eliminating common parsing errors and reducing the need for manual validation.

Which Claude models are currently active in 2026?

The active frontier models include Claude Opus 4.5, Sonnet 4.5, and Haiku 4.5. Older 3.x models, including 3.5 and 3.7 Sonnet, have been retired or deprecated.

Master the Anthropic Claude Messages API with advanced patterns for structured outputs, prompt caching, and robust error handling.

This skill provides comprehensive guidance for developers building on the Claude Messages API, specifically focusing on modern features introduced in SDK v0.69.0 and beyond. It offers production-ready implementation patterns for guaranteed JSON schema conformance through structured outputs, significant cost reduction strategies using ephemeral prompt caching, and resilient tool-use configurations. By addressing 16 common pitfalls—including mid-stream SSE parsing errors, Unicode edge cases in tool results, and model deprecation migrations—it ensures your AI applications remain efficient and compatible with the latest Claude 4.x frontier models.
