Repeated Instructions Question Explained
This worked Loop Engineering practice question tests Checkable Tasks. Try the answer first, then review why B is the best choice.
Short answer
The correct answer is B. In a CLAUDE.md file in the project folder, loaded when a session starts there.
Claude Code loads CLAUDE.md from the working directory and the directories above it when a session starts. Rules that apply to the whole project belong there, and individual changes stay in the task file. The memory docs also say Claude treats CLAUDE.md as context, not enforced configuration. To block a package install every time, add a deny rule or a PreToolUse hook as well. The correct answer is B. In a CLAUDE.md file in the project folder, loaded when a session starts there
The Question
Every session you type "Keep the page and CSS in one HTML file, do not add packages." Yesterday a loop run added a package anyway. Where should that rule live?
Why B is correct
Claude Code loads CLAUDE.md from the working directory and the directories above it when a session starts. Rules that apply to the whole project belong there, and individual changes stay in the task file. The memory docs also say Claude treats CLAUDE.md as context, not enforced configuration. To block a package install every time, add a deny rule or a PreToolUse hook as well. The correct answer is B. In a CLAUDE.md file in the project folder, loaded when a session starts there
Why the other options are wrong
Repeating the rule on every task line works until you add one task without it. A rule for the whole project belongs in one project file.
An alias prints the rule in your terminal before Claude starts. That text is not part of the session, so the model never receives it.
The rule applies in normal sessions too, not only in loops. A prompt-only rule disappears the first time you type a task by hand.
Key idea: Checkable Tasks
Loop engineering is a practice skill. Open Claude Code in a throwaway folder, write one small task in a file, and run it with /loop or /goal while you watch. If you doubt an answer, test it against a real run in that folder.
