Claude Platform 101

The whole developer course, testable: the platform's three layers, your first messages.create, choosing a model, the agent loop, tool use, thinking, built-in tools, Skills, MCP, context management, and managed agents. Recognition questions with hints on, with the trap-spots built in on purpose (response content is an array not a string, your code runs the tool not Claude, pick the cheapest model that ships, Skills load progressively, and you open the event stream before the kickoff).
