name	claude-api
description	Load Claude API reference material for your project's language (Python, TypeScript, Java, Go, Ruby, C#, PHP, or cURL). Use when the user asks about using Anthropic SDKs, tool use, streaming, or structured outputs.

When the user asks about Claude API or Anthropic SDKs:

1. Activate automatically when code imports anthropic, @anthropic-ai/sdk, or claude_agent_sdk.

2. Provide reference for:

   • Tool use (function calling)
   • Streaming responses
   • Message batches
   • Structured outputs (JSON mode)
   • Common pitfalls (e.g., token limits, prompt engineering)

3. Current SDKs:

   • TypeScript: @anthropic-ai/sdk
   • Python: anthropic
   • Go, Java, Ruby, C#, PHP (via community or direct REST)

4. Key Concept: Always use the messages API, not the legacy completions API.
