What problem does it solve?

This Skill helps update the @github/copilot package safely by coordinating version upgrades, type definition comparisons, compilation checks, and test validation in a disciplined sequence.

Core Features & Use Cases

• Type Change Analysis: Compares old and new SDK definitions to document API changes, breaking changes, and new capabilities in upgrade notes.
• Build and Test Remediation: Repeatedly compiles, fixes type or build issues, and runs unit tests until the upgrade is stable.
• Use Case: A maintainer needs to move a project to the newest Copilot release while preserving compatibility and documenting the impact for the team.
