{
  "context": "Negative case — tests whether the skill refuses to silently overwrite an existing non-empty directory. The scaffold flow is destructive (writes build.gradle.kts, Main.kt, .gitignore at known paths) and silence here would clobber the developer's previous work without consent.",
  "type": "weighted_checklist",
  "checklist": [
    {
      "name": "Detects the non-empty state before writing",
      "description": "The plan checks whether the target directory is empty before writing any file. The check happens at the start, not after some files have already been written",
      "max_score": 25
    },
    {
      "name": "Refuses to proceed without explicit confirmation",
      "description": "The plan does NOT write any files in this state. It either aborts, or pauses and asks the developer for explicit confirmation to overwrite — silence is not treated as consent",
      "max_score": 30
    },
    {
      "name": "Asks an explicit yes/no overwrite question",
      "description": "If the plan asks the developer, the question is direct and binary: confirm overwrite yes or no. Not a vague \"how should I handle the existing files\" prompt that could be answered ambiguously",
      "max_score": 20
    },
    {
      "name": "Names what would be overwritten",
      "description": "Surfaces the existing files (README.md, src/, build.gradle.kts) so the developer understands what they would lose if they confirm. A blind \"directory is not empty\" without a file list is insufficient",
      "max_score": 15
    },
    {
      "name": "Leaves the directory unchanged on refusal",
      "description": "On the abort path (no confirmation given), the plan describes no destructive operations — no rm, no overwriting files, no creating new files alongside the existing ones",
      "max_score": 10
    }
