In this lesson
Prepare for the Claude Certified Developer – Foundations exam, on the exam guide version 1.0, effective July 2026. In this lesson: a finite context window and just-in-time loading, drift and context bloat, pruning, clearing, and compaction, memory files and subagents for isolation, structured outputs and strict tool use, stop reasons, validation, and answers grounded in sources. Includes three original practice questions.
Preview the topics
- Driftwood’s agent reads dozens of large files early in a session, and twenty turns later, those raw file contents still fill most of its context. Which technique targets them directly?
- Driftwood’s main agent must research twelve suppliers, and each search returns pages of results that crowd its context. Which design fits?
- Driftwood parses each JSON answer right away, and its parser fails now and then on an answer that stopped at max_tokens, even though structured outputs are on. What should the code do first?
