Claude Code Configuration & Workflows (D3)

CLAUDE.md, slash commands, hooks, plan mode, dev workflows.

Claude Code Configuration & Workflows (D3) is about bending Claude Code to a real codebase: how you structure CLAUDE.md, when you reach for plan mode, and how you encode your team's conventions so they load at the right moment. The exam tests practical configuration, not trivia.

Expect questions on CLAUDE.md hierarchy, scoping, and modular organization, creating custom slash commands and skills, applying path-specific rules for conditional convention loading, choosing plan mode versus direct execution, iterative refinement techniques, and wiring Claude Code into CI/CD pipelines.

This domain spans 6 subtopic areas, covered by 122 practice questions across 24 easy, 67 medium, and 31 hard items.
