Agent Usage
When the user asks to preview a diff, DO NOT build HTML manually. Use the Bash tool to execute this skill's run.sh script:
# Preview current changes
git diff HEAD | ./run.sh
# Preview specific branch comparison
git diff main..feature-branch | ./run.sh
The script handles all HTML generation and automatically opens the result in the browser. Do NOT open the file manually to avoid duplicate tabs.
Options
The script works with sensible defaults but supports these flags for flexibility:
-o, --output PATH- Custom output path--no-browser- Skip browser, output file path only
