Builder Product Updates

Delegate work to specialized agents like a code reviewer, debugger, or test runner. Sub agents run in their own context windows, and Builder can automatically route tasks to the right one. Learn more

A new real-time view for PRs that makes async collaboration easier. Open branches attached to a PR so feedback doesn't bottleneck on a single developer.

A new real-time view that shows branch status across In progress, In review, Merged, and Archived. It gives you better visibility into what is moving forward and helps you stay focused on the branches you are actively working on.

Define reusable instructions for recurring tasks so your agent follows your preferred approach every time. Learn more

We’ve seen strong results using it for quick final-stretch iteration, debugging, and polish.

You can now submit messages while the agent is running without interrupting the current task. Messages are added to a queue and handled intelligently in order.

Edit, reorder, or remove queued messages at any time.

You can connect projects to Fusion over SSH, not just through Git providers. Switch the Desktop App provider to SSH, paste an SSH URL, and Fusion will parse the repo, create a local project, and push branches as you iterate. Great for self-hosted or locked-down repos where OAuth is a non-starter.
