Jira automatic follow up via direct dm in slack

yep, you can do this with Jira Cloud Automation. go to your space settings > Automation > Create rule, pick Scheduled, and run it once a week. use JQL like project = ABC AND status in ("Open", "In Progress") AND assignee is not EMPTY. then add the "Send Slack message" action, paste in a Slack incoming webhook, and add your reminder text. Jira will run the action once for every issue returned by that query. Here’s the scheduled-trigger documentation. if you mean one DM to each assignee, there’s one fiddly part: Jira’s assignee ID and the person’s Slack member ID aren’t the same. for a small team, the easiest setup is one rule per person, with that assignee in the JQL and their Slack ID in "Channel or user", for example u/U123ABC. for a larger team, use a Slack app to look up the member ID from {{issue.assignee.emailAddress}}, then pass {{webResponse.body.user.id}} into the Slack action. Atlassian has an exact DM example and the webhook setup here. test with one issue and check the automation audit log first. otherwise someone with 15 open issues gets 15 surprise DMs 😅

At a high-level, you'll want to create an Automation Rule (or Flow) that is configured to 'Send a Slack message'. This will require the Slack user to have a Slack app called 'jira service Management ChatOps' installed.
