CCDV-F objective 3.1 · Domain 3 · 3.1% of the exam
Claude Code Operation
Eight items, and they reward knowing what each surface costs at load time. Instruction files concatenate up the directory tree rather than override, so a personal habit and a project convention both apply inside a checkout. A skill contributes its description until invoked; a path-scoped rule waits for a matching file; an import expands at launch and saves nothing. Know the modes apart as well: one substitutes a classifier for the human reviewer, one denies instead of prompting, and one drops both.
