generate-custom-instructions-from-codebase

Generate GitHub Copilot instructions for code migration by analyzing code differences between source and target references. The Skill identifies structural changes, API correspondences, and obsolete patterns to create a comprehensive guide for automated code evolution.

Code migration instructions are actionable rules for AI code assistants that define how to apply code evolution patterns during refactoring. You need them when migrating large codebases between framework versions to ensure automated consistency and adherence to new conventions.

Yes, you can automate code refactoring with GitHub Copilot using source and target reference files. The analysis detects code transformations and new patterns, outputting a `.github/copilot-migration-instructions.md` file to guide the AI assistant.

The best way to upgrade a codebase across framework versions is to compare project versions to identify structural and API transformation patterns. This generates detailed instructions for Copilot to automatically apply necessary changes and maintain consistency.

Yes, this code evolution analysis works without external dependencies. It operates directly on your provided source and target references to identify structural changes and code transformations, generating a standalone markdown file for GitHub Copilot.
