The reference, the recipes, the topics, and how to connect - every example executed by the engine that will run yours.
Every symbol, with its availability stated first, its forms, and examples that were actually run.
Multi-step tasks, each step verified in sequence, from a limit to a differential equation.
The reference grouped by subject, so the function you need is next to the ones you will need after it.
Connect Claude, Cursor, VS Code or any MCP client: endpoints, sign-in, the tools and the limits.
The REST surface, authentication, and the OpenAPI document that describes it formally.
