Connecting Slack now gives PlayerZero a set of Slack tools it can use during Player threads and workflow runs, so Slack is somewhere PlayerZero works rather than only somewhere it sends notices. It can find a channel and read its recent history, search earlier messages, read a full Slack thread, post an update, reply in the thread where your team is already talking, revise or delete a message it posted itself, and look up teammates by profile, email address, or channel membership. The tools come with the Slack connection: there is nothing to create, and no credential to manage. Organization owners choose which tools PlayerZero may call from Organization Settings under Collaboration, on the Slack MCP row, and other organization members can read that list without being able to change it. The tools follow the project access already set on the Slack connection, and posting, revising, or deleting a message falls under the privileged action approval setting when you have it turned on. If your organization connected Slack before this release, an organization owner needs to reconnect it to grant the workspace permissions the tools need.A workflow that finishes an investigation can post the result into the channel that cares about it and answer the follow-up question in the same Slack thread, so the work and the conversation about it stay in one place instead of being copied across by hand.
