A workflow, start to finish
One worked example you can copy.
Say you want this: every weekday morning an agent checks what changed, writes a summary, you approve it, and it goes to the team channel.
1. New workflow. Workflows, then New workflow. Name it Morning digest.
2. The trigger. Click the Trigger card, pick Schedule, choose Every weekday at 8:00. Set Activity and questions go to to the channel where you want to be asked things.
3. Step one: agent task. Add a step, pick Agent task, choose the agent, and write the job: "Check the changes since yesterday and write a five-line summary for the team." Leave Post the result off - you do not want the draft in the channel yet.
4. Step two: ask a human. Add Ask a human with the question "Send this digest?" and include {{last}} so you see the draft inside the question.
5. Step three: post it. Add Post to group, pick the channel, and put {{steps.1.output}} as the message - that is the summary from step one, not your approval.
6. Try it. Press Run now. You land on History and watch it run. Approve the question when it appears in your Inbox.
7. Turn it on. Flip the switch from Disabled to Enabled. A workflow that is off never fires, however good the schedule is.
