score: integer 0-100
verdict: short status (pass, revise, or fail)

---name: visual-verdictdescription: Structured visual QA verdict for screenshot-to-reference comparisons---<Purpose>Use this skill to compare generated UI screenshots against one or more reference images and return a strict JSON verdict that can drive the next edit iteration.</Purpose><Use_When>- The task includes visual fidelity requirements (layout, spacing, typography, component styling)- You have a generated screenshot and at least one reference image- You need deterministic pass/fail guidance before continuing edits</Use_When><Inputs>- `reference_images[]` (one or more image paths)- `generated_screenshot` (current output image)- Optional: `category_hint` (e.g., `hackernews`, `sns-feed`, `dashboard`)</Inputs><Output_Contract>Return **JSON only** with this exact shape:```json{ "score": 0, "verdict": "revise", "category_match": false, "differences": ["..."], "suggestions": ["..."], "reasoning": "short explanation"}```Rules:- `score`: integer 0-100- `verdict`: short status (`pass`, `revise`, or `fail`)- `category_match`: `true` when the generated screenshot matches the intended UI category/style- `differences[]`: concrete visual mismatches (layout, spacing, typography, colors, hierarchy)- `suggestions[]`: actionable next edits tied to the differences- `reasoning`: 1-2 sentence summary<Threshold_And_Loop>- Target pass threshold is **90+**.- If `score < 90`, continue editing and rerun `$visual-verdict` before any further code edits in the next iteration.- Persist the verdict in `.omx/state/{scope}/ralph-progress.json` with both: - numeric signal (`score`, threshold pass/fail) - qualitative signal (`reasoning`, `suggestions`, `next_actions`)</Threshold_And_Loop><Debug_Visualization>When mismatch diagnosis is hard:1. Keep `$visual-verdict` as the authoritative decision.2. Use pixel-level diff tooling (pixel diff / pixelmatch overlay) as a **secondary debug aid** to localize hotspots.3. Convert pixel diff hotspots into concrete `differences[]` and `suggestions[]` updates.</Debug_Visualization><Example>```json{ "score": 87, "verdict": "revise", "category_match": true, "differences": [ "Top nav spacing is tighter than reference", "Primary button uses smaller font weight" ], "suggestions": [ "Increase nav item horizontal padding by 4px", "Set primary button font-weight to 600" ], "reasoning": "Core layout matches, but style details still diverge."}```</Example>
