Connection facts
These details come from the current StackOS provider manifest and action catalog. They describe the available connection—not a promise that every workflow will use every action.

Actions listed for this integration. Individual descriptions note availability limits. A workflow still decides which actions belong in the job and where approval is required.

Direct answer
People continue using Slack Bot as their tool. StackOS adds it to a visible workflow, keeps the work in order, and passes only the approved action to the integration when that stage is ready.
Common questions
The current catalog includes 10 Slack Bot actions across Messaging. The exact actions used depend on the workflow and approval rules.
No. Slack Bot remains the tool that performs its part of the job. StackOS organizes the workflow, keeps status and dependencies visible, and calls the tool only when the plan reaches the right approved action.
