How This Skill Works
Official Anthropic skill that makes the agent an accurate guide to building on the Claude API. It detects your language (Python, TypeScript, Java, Go, Ruby, C#, PHP, cURL), helps you pick the right surface (single call, tool-use loop, or Managed Agents), and points to the exact SDK patterns.
Covers current model IDs and pricing, streaming, tool use, structured outputs, prompt caching, batches, token counting, and model migration — so the agent stops guessing at the API and writes code that actually compiles against the current SDK.
