SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you implement production-ready Claude (Anthropic) API and SDK workflows while avoiding common integration pitfalls that cause runtime errors, incorrect tool use, or non-Claude code paths.

Core Features & Use Cases

  • Claude SDK-first integration: Ensures you call the official Anthropic SDK by language (or raw HTTP only when explicitly requested), with guardrails against accidentally generating OpenAI-provider-compatible code.
  • Practical defaults for real apps: Sets consistent model behavior expectations (including Opus 4.7 as the default) and recommends adaptive thinking and streaming for long outputs.
  • Tool use and agentic workflows: Supports tool calling patterns, manual and automated loops, structured outputs, prompt caching, and context compaction for long-running sessions.
  • Reading guide by task type: Directs you to the right sections for single-call tasks, streaming UIs, prompt caching, migration, and managed agents concepts.

Quick Start

Ask for a Claude SDK integration for your current language and tell the assistant what you’re building (e.g., single request, streaming UI, tool use loop, or migration to a newer model).

FAQPage Schema
How do I implement Claude API tool use and agentic loops with the Anthropic SDK?

Claude API streaming is implemented via the Anthropic SDK Messages API to stream chunks to real-time UIs. It is recommended for long outputs and pairs with adaptive thinking on models like Opus 4.7.

How do I migrate to current Claude model IDs safely in my SDK integration?

Claude model migration involves updating to current model IDs in your Anthropic SDK configuration while applying correct model defaults and parameters. This ensures safe migration without breaking existing Messages API calls.

Does the Claude API support prompt caching for long-running sessions?

Yes, Claude API prompt caching is supported through the Anthropic SDK to reduce latency and costs in long-running sessions. It integrates with context compaction and tool use workflows for production applications.

What is the best way to build a Claude SDK integration without OpenAI-compatible shims?

The best way to build a Claude SDK integration is calling the official Anthropic SDK directly by language, using guardrails to prevent OpenAI-compatible code paths. This enforces strict Claude SDK usage with correct model defaults.
