  REST, JSON and Asynchronous Application Code: Ep. 6 14.10.2026 10min

  What happens when a request is accepted but the work is unfinished, or a notification is sent but its acknowledgement never arrives? A fictional repair-desk application brings HTTP contracts, JSON validation and asynchronous scheduling into focus. You'll examine dependent and concurrent work, bounded queues, deadlines, cancellation and retries, then use delivery evidence to resolve an uncertain outcome before repeating a side effect. Practice questions help connect the code's behavior to the result the application can safely claim.Independent Exam Prep with original scenarios and questions.

  Streaming, Batches and Provider Integration: Ep. 5 14.10.2026 9min

  Live repair assistance and overnight analysis need different ways of working. Follow both workloads to learn how to track streamed content, recognize completion and recover from interrupted responses. Then work through batch identifiers, out-of-order results and item-by-item recovery. The lesson connects those choices to model providers, authentication and deployment configuration, and explains why prompt caching depends on an eligible matching prefix rather than simply reusing the same words somewhere in a request.Independent Exam Prep with original scenarios and questions.

  Messages, Tools, Vision and Thinking: Ep. 4 14.10.2026 9min

  A print shop needs to investigate a possible mistake on a poster using a photograph and a job record. Trace the interaction through structured Messages API content, a client-tool request, application-side authorization and the returned result. You'll examine uncertain image readings, tool-call identifiers, error results and the thinking blocks needed for a valid continuation. Original practice questions reinforce the difference between what the model requests, what the application executes and what the evidence actually supports.Independent Exam Prep with original scenarios and questions.

  Requirements and the Systems Life Cycle: Ep. 3 14.10.2026 10min

  A convincing prototype is only the beginning. Follow a fictional maintenance-request assistant from its business brief through design, testing, deployment, operation and retirement. Learn to separate functional, infrastructure and nonfunctional requirements, write testable acceptance criteria, and gather evidence across the actual data path. The lesson also covers held-out evaluations, release ownership and recovery plans, including why saving an old prompt is not enough to make rollback work.Independent Exam Prep with original scenarios and questions.

  SDKs, REST and Communication Fundamentals: Ep. 2 14.10.2026 10min

  A museum wants a visitor app that answers questions while keeping its interface responsive. Should the team choose an SDK, REST, asynchronous code or streaming? Follow a request from the application to Claude and back to see how those choices fit together. This lesson separates client libraries, HTTP, JSON, async scheduling, batches, server-sent events and WebSockets, then examines why a successful connection or a few displayed sentences do not prove the answer is complete.Independent Exam Prep with original scenarios and questions.

  Tokens, Sampling, Context and Thinking: Ep. 1 14.10.2026 9min

  Why can the same build log produce two confident but different explanations? This opening lesson uses a software-build assistant to explore how tokens, sampling and context shape a response, and why fluent wording needs supporting evidence. You'll work through input capacity, output allowances, prompting with examples, and the differences between thinking, effort and speed. Short practice questions help you test the distinctions before moving into API integration.Independent Exam Prep with original scenarios and questions. No Anthropic affiliation or endorsement.
