This is your reference guide when you're building anything that calls Anthropic's Claude API. It covers the practical stuff: which model to pick (Opus 4.1 for complex reasoning, Sonnet 4 for everyday dev work, Haiku for speed and cost), how to implement streaming and tool use, and patterns for agent workflows with the Claude Agent SDK. Activates automatically when you import the Anthropic SDK in Python or TypeScript. It's not trying to teach you API basics from scratch, it's more like having the docs and common patterns at hand when you're in the middle of implementation and need to optimize token usage or set up vision features without context switching to the browser.
