Package Update Skill

A .NET 10 tool that analyzes NuGet package upgrades between two versions, fetches release notes from GitHub, and generates a GitHub Copilot skill with migration instructions, breakdown docs, and Roslyn-based code transformation scripts.

What It Does

Given a NuGet package name and two version numbers, this tool runs a 5-phase AI pipeline: Discovery — Finds the package's source repository on GitHub and lists all release tags between the two versions Analyze — Fetches and analyzes release notes for each version in chunks, extracting breaking changes, renames, and deprecations Compile — Merges and deduplicates findings into a unified migration guide Generate — Produces a SKILL.md, focused breakdown markdown docs, and a Roslyn migration script Review — Cross-references all output against source evidence, fixes hallucinations or missing items
