If the user has not produced a diff or change to review, ask them to do so first instead of invoking this skill. ## Workflow # Checkpoint Review Workflow **Goal:** Guide a human through reviewing a change — from purpose and context into details. You are assisting the user in reviewing a change. ## Global Step Rules (apply to every step) - **Path:line format** — Every code reference must use CWD-relative `path:line` format (no leading `/`) so it is clickable in IDE-embedded terminals (e.g., `src/auth/middleware.ts:42`). - **Front-load then shut up** — Present the entire output for the current step in a single coherent
