Turn code changes into Copilot migration rules.
Creates GitHub Copilot migration instructions from differences between two project states so future changes follow the same transformation patterns.
When to use it
Use when documenting framework upgrades, technology replacements, architecture refactoring, or design pattern modernization.
Give it a project and its before-and-after references; it creates .github/copilot-migration-instructions.md with transformation rules derived from the changes.
