Dev Visual Verdict

Derived from oh-my-claudecode (MIT, Yeachan Heo). Adapted for the EvoNexus Engineering Layer.

Visual regression testing. Capture before/after screenshots of UI components, compare them, and flag unintended visual impact.

Use When

• CSS / styling change that might cascade to other components
• Component refactor where the visual output should remain identical
• Theme change that needs to be verified across the app

Do Not Use When

• Backend-only changes
• Intentional redesigns (use @canvas-designer instead)
• Single-component changes with obvious visual outcome

Workflow

1. Identify scope — which components could be affected
2. Capture baseline — screenshot current state of each affected component
3. Apply change — let @bolt-executor make the modification
4. Capture after — screenshot post-change state
5. Compare — flag any visual differences (pixel-level or layout-level)
6. Verdict — IDENTICAL / EXPECTED CHANGES / UNEXPECTED REGRESSION

## Visual Verdict — {component}

### Scope
- Components checked: [list]

### Comparison
| Component | Before | After | Diff | Verdict |
|---|---|---|---|---|
| Header | ![](before-1.png) | ![](after-1.png) | 0% | IDENTICAL |
| Footer | ![](before-2.png) | ![](after-2.png) | 12% | UNEXPECTED |

### Verdict
{IDENTICAL | EXPECTED CHANGES | UNEXPECTED REGRESSION}

### Unexpected Regressions
- Footer color shifted from #1A1A1A to #2A2A2A — investigate cascade

Pairs With

• @canvas-designer (when regression is intentional)
• @hawk-debugger (when regression is unintended)
• @oath-verifier (final visual verification)
