Cursor in Slack Now Posts a Plan Before Executing and Can Read/Write Across Channels

Cursor Changelog·medium signal

The July 17 update makes Cursor share a plan before it starts work, stream status updates during execution, support multi-repo environments with mid-task repository switching, and read from and post to other Slack channels and threads. Cross-channel read is the meaningful capability change — the agent's context now spans conversations it wasn't invoked in. That is also the new injection surface: anything anyone types in a readable channel is agent input.
