1. Cursor 3.12 Deepens the Slack Integration with Planning and Multi-Repo Support

Cursor. Cursor 3.12 upgraded how the agent works inside Slack, with the agent now sharing a plan before it starts a task so users can redirect it early. The release added support for multi-repo environments that can be reached directly from Slack and cross-channel workflows that let the agent read and send messages across different channels and threads. Cursor also refined how responses render in Slack, replacing in-message buttons with compact footer links for cleaner display of tables, pull requests, and artifacts. Source
