Verdict visuel

name: visual-verdict

description: Structured visual QA verdict for screenshot-to-reference comparisons

level: 2

<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:

{
  "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

<ThresholdAndLoop>

• Target pass threshold is 90+.
• If score < 90, continue editing and rerun /oh-my-claudecode:visual-verdict before any further visual review pass.
• Do not treat the visual task as complete until the next screenshot clears the threshold.

</ThresholdAndLoop>

<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>

{
  "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>
