VS Code inserts 'Co-Authored-by Copilot' into commits regardless of whether Copilot was used

·2026.05.03 04:57

Key point

The VS Code Git extension has changed so that it attaches `Co-authored-by` to commits regardless of whether Copilot was used.

Details

A change has landed in the VS Code Git extension that flips the default value of git.addAICoAuthor from "off" to "all". The direction is to automatically attach a Co-authored-by trailer to commits when AI-generated code contributions are detected.

  • The runtime fallback in extensions/git/src/repository.ts still uses "off", which is inconsistent with the schema.
  • Concerns have been raised that in some environments the intended default may not actually take effect.
  • Cases have been reported where Co-authored-by Copilot gets attached even though Copilot wasn't used, and this has been followed by reactions demanding that the default be withdrawn.
