Generate Plan Peer Review Prompt

Step 1: Resolve the plan path

If $ARGUMENTS contains a path, resolve it to its absolute path and skip the interactive selection below.

If no argument was provided, auto-detect plan candidates and present an interactive selection:

1. Detect candidates (run these in parallel):

   • Check git diff --name-only for recently modified plan/doc files
   • Check git log --oneline -5 --diff-filter=AM -- 'docs/plans/**/*.md' for recently added/modified plans
   • Look for plan files/directories matching docs/plans/**/*.md
   • Check if a plan file was recently read or discussed in this session

2. ALWAYS present an AskUserQuestion multiple-choice UI with up to 4 detected candidates. Never just ask a text question — always use the interactive chip UI. Example:

   AskUserQuestion(questions: [{
     question: "Which plan do you want to review?",
     header: "Plan",
