About this tag
The github copilot sdk tag on WindowsForum.com gathers discussion of Microsoft's toolkit for building coding-agent extensions and AI-assisted developer workflows. Coverage here centers on a Microsoft developer experiment that ran GPT-5.6 Luna through the GitHub Copilot SDK with external information access removed, testing whether a model's knowledge cutoff predicts the product versions it can actually handle. The findings showed no clean relationship, with failures on older features and occasional successes on newer releases, and they touch on Dev Proxy and SharePoint Framework work. For Windows developers, the recurring theme is practical: test representative tasks before deciding what documentation an agent needs.
