   Question 1 of 5: Question 1: /init

   When a CLAUDE.md already exists.

   In Claude Code

   – What happens: This folder already has a CLAUDE.md.

   You type: › /init

   Your project already has a CLAUDE.md. What does /init do?

   • AA. Replaces it with a new file.
   • BB. Suggests improvements instead of overwriting it.
   • CC. Asks you to delete it first.

   Show the answer

   The answer is B.

   /init suggests improvements rather than overwriting an existing CLAUDE.md.

   Reread Day 1: Set up Claude Code and CLAUDE.md or the memory docs.

   What Claude does while plan mode is on.

   In Claude Code

   You type: › add a --currency flag to the quote command

   Output: ⏸ plan mode on

   You ask for a feature in plan mode. What does Claude do?

   • AA. Edits files, asking before each one.
   • BB. Nothing until you approve.
   • CC. Explores and writes a plan, without editing your source.

4. 04

   Question 4 of 5: Question 4: an unrelated task

   What to do with the old conversation.

   In order:

   1. Claude

      Bug fixed

      Tests pass, work committed

   2. You

      README rewrite next

      Unrelated to the bug

   The bug is fixed. Next is a README rewrite that has nothing to do with it. What do the docs recommend?

   • AA. Keep going so Claude remembers the fix.
   • BB. Run /compact.
   • CC. Run /clear.

   Show the answer

   The answer is C.

   Old conversation crowds out what Claude needs next and costs tokens on every message.

   Reread Day 6: Keep the context clean or the context window docs.

5. 05

   Question 5 of 5: Question 5: allow versus deny

   Two rules match one command.

   .claude/settings.json

   permissions.allow: ["Bash(npm run *)"]

   Approves without asking

   permissions.deny: ["Bash(npm run deploy)"]

   Blocks

   Claude tries npm run deploy with the two project rules above. What happens?

   • AA. It runs: the allow rule matches.
   • BB. It’s blocked: deny rules are checked first.
   • CC. Claude Code asks, because the rules conflict.

   Show the answer

   The answer is B.

   The order is deny, then ask, then allow, however specific a rule is.

   Reread Day 9: Allow, ask and deny rules or the permissions docs.

   Pick an answer to go on.
