Prepare for the Claude Certified Developer – Foundations exam, on the exam guide version 1.0, effective July 2026. In this lesson: the core agent loop with a turn limit and a budget, long-term memory outside the context window, compaction and clearing old tool results, frameworks (Strands Agents, LangGraph, Pydantic AI) versus the Agent SDK, and how to choose. Includes three original practice questions.
Preview the topics
- Driftwood’s agent works on a migration over several sessions, and each new session repeats work that was already done. What helps most?
- Driftwood needs a refund workflow that pauses for a manager’s approval, survives a server restart, then resumes where it stopped. Which framework feature matters most?
- An agent built with a framework picks the wrong tool, and nobody can see the prompt that the framework sends. What should come first?
