Git Visualizer

Use this skill to turn git diff output into a single HTML page that's easy for a human to scan and review. The default mode reviews uncommitted working-tree changes, but it also handles staged-only, single commits, arbitrary ranges, and "my branch vs main".

Unlike the plan-visualizer, you do NOT need to extract structured data yourself — git already produces structured output, and the bundled script parses it. Your job is almost entirely to pick the right command-line invocation for what the user wants to review, then run the script.

When to use

Trigger this any time the user wants a visual, reviewable diff. Common phrasings:

• "visualize my git changes"
• "show me what I'm about to commit"
• "render the diff / render my changes"
• "I want to review my branch before pushing"
• "visualize this commit / PR / range"
• "make the diff easier to skim"
