GitHub Copilot Workspace

Copilot Workspace takes a GitHub Issue and turns it into a specification, implementation plan, and actual code changes before a developer writes a line — you review and edit the plan, then let it generate code across multiple files, all in the browser with a built-in terminal for running tests. It's GitHub's attempt to push Copilot from an autocomplete tool toward a genuine development collaborator that can go from bug report to reviewed PR.
