What it does

Analyzes differences between two project versions (branches, commits, or releases) to generate migration instructions for GitHub Copilot during framework upgrades or major refactoring.

Overview

Generate Custom Instructions from Codebase is a GitHub Copilot skill that creates migration and code evolution instructions by analyzing differences between two project versions. It compares branches, commits, or releases to produce precise instructions that allow Copilot to maintain consistency during technology migrations, major refactoring, or framework version upgrades.

Key Features

Version comparison analysis: Compares two project versions (branches, commits, or releases) to identify patterns of change.
Migration instruction generation: Produces detailed instructions that guide AI-assisted code transformations to follow established migration patterns.
Consistency enforcement: Ensures that Copilot-generated code during migrations follows the same conventions and patterns found in already-migrated code.

Who is this for?

This skill is designed for development teams undertaking technology migrations, framework upgrades, or large-scale code refactoring who want AI assistance that follows consistent patterns. It is particularly valuable for teams migrating large codebases where manual instruction writing would be time-consuming and error-prone.
