Disable Claude co-attribution in commits/PRs by Copilot · Pull Request #4788 · microsoft/vscode-copilot-chat

Copilot · 2026-03-27T22:38:28Z

When using Claude in Copilot, we shouldn't be attributing PRs to Claude.

The Claude Agent SDK supports disabling the "Co-authored-by: Claude" attribution added to git commits and pull requests, and this PR uses the attribution settings API with empty strings for commit and pr to suppress this attribution on Claude agent-authored code.

@copilot I don't want you to add a new setting, I want you to just disable it in our agent SDK configuration for Claude.

@copilot I don't want you to add a new setting, I want you to just disable it in our agent SDK configuration for Claude.

Done — removed the setting and hardcoded includeCoAuthoredBy: false in the SDK settings object in claudeCodeAgent.ts. Reverted all changes to package.json, package.nls.json, and configurationService.ts. See 54432ac.

Switched to the attribution API with empty strings for commit and pr instead of the deprecated includeCoAuthoredBy. See eaad1d8.

The PR description doesn't mention why this is being done (and no reference to an issue). Isn't this removing transparency around AI usage?
