Jules has started its “Sharpening the tools” launch! Today's drop adds PR comments in GitHub, a stacked diff viewer, targeted reliability fixes, GitHub repo initialization for fresh starts, and native file upload in the web app. The updates ship to developers using the Jules web interface and its GitHub integration.
The @julesagent code review got a major update.

Jules can now reply directly to review comments with code-aware context, cutting bounce between chat and code. The new stacked diff UI consolidates changes to help reviewers track what moved and why. A fix addresses one of the most common environment failures, prioritized from user logs. Repo initialization auto-creates and configures a GitHub project for new users. File upload lets teams bring assets straight into Jules without a repo commit or public URL.
Why it matters: the release tightens feedback loops in code review and shortens setup for new projects. It follows August’s momentum and sets the stage for a second September launch focused on reach and workflow breadth.
Jules is Google’s async coding agent aimed at teams that want plans, diffs, tests, and PRs generated off a task rather than inline typing. It runs tasks against your repo and returns a reviewable pull request, positioning itself as a proactive collaborator across the development workflow. The team behind Jules is using paired launch weeks to mature reliability first, then expand coverage later this month.
