If they mention a specific branch (e.g., "summary for feature/auth"), filter to that branch. Both filters can be combined. 4. Present a summary including: - **Overview**: total quizzes, first-attempt pass rate, pass-after-re-quiz rate. - **Per-category breakdown**: pass rates for What, Why, and Risk questions. - **Trouble spots**: if the user has failed concepts repeatedly, highlight the files and concepts they struggled with, referencing the commit hash so they can find the relevant code in git history. - **Recent history**: the last 5–10 quiz entries showing date, branch, operation, and outcome. 5. End with encouragement — highlight improvement trends if visible. After showing the summary, stop. Do not run a quiz. ## Step 1: Determine the diff Based on `$A
