/erne-debug-visual — Visual Debugging

You are executing the /erne-debug-visual command. Use the visual-debugger agent for screenshot-based UI analysis and fixing.

Arguments

/debug-visual                          — auto-capture screenshot from running simulator/emulator via agent-device
/debug-visual <file>                   — analyze a specific screenshot file
/debug-visual --compare <figma-file>   — compare app screenshot with Figma export
/debug-visual --screen <ScreenName>    — navigate to and capture a specific screen

Process

Step 1: Capture Screenshot

• No args: auto-capture from running simulator/emulator via agent-device
• <file> provided: read the specified screenshot file directly
• --compare: capture live app screenshot AND read the Figma export file
• --screen: navigate to the named screen first, then capture

Step 2: Analyze

1. Apply multimodal vision to the screenshot(s)
2. Read the relevant component source files
3. Identify all visual issues
4. Present a numbered list — each item includes category and severity:

Category	Examples
Layout	overflow, misalignment, wrong spacing
Typography	wrong font, size, weight, truncation
Color	wrong token, contrast failure, dark mode
Spacing	padding/margin off-spec
Responsive	breaks on small/large screen
Figma Delta	deviation from design (--compare only)

Severity: critical · major · minor

Step 3: Interactive Fix

1. User picks issue numbers to fix
2. Locate the responsible component in source
3. Apply the fix (minimal change, match project style)
4. Hot reload — allow ~2s for changes to reflect
5. Re-capture screenshot
6. Show before/after comparison
7. Ask: "Does this look correct? Any remaining issues?"

Step 4: Summary

• Issues detected (count by severity)
• Fixes applied with before/after diff per issue
• Remaining issues (if any deferred by user)
• Save findings to memory for future reference
