How it runs

The automated pipeline, trigger to output.

  • TriggerSchedule fires every 3 hours during work hours
  • ActionList open PRs with pending review requestsGitHubGitHub
  • LogicKeep only PRs past the review SLA with no review yet
  • ActionResolve each reviewer's GitHub login to a Slack userSlack
  • OutputDM each stale reviewer the PR link and hours waitedSlack

What it does

Keeps review queues moving by catching pull requests that have been waiting on a specific reviewer longer than your agreed turnaround. Instead of one noisy channel blast, it pings each individual reviewer privately with exactly the PR they're blocking and the elapsed wait time.

When to use it

When your team has a stated review SLA (say, 24 business hours) and PRs routinely stall because a requested reviewer forgot. Best for teams that want gentle, targeted accountability rather than a public shame list.

How it works

  1. 1A schedule fires every few hours during working hours.
  2. 2The flow queries GitHub for all open PRs with pending review requests.
  3. 3A logic step keeps only PRs whose `review_requested` timestamp is older than the SLA threshold and that have no review yet.
  4. 4For each survivor, it resolves the reviewer's GitHub login to a Slack user.
  5. 5It sends that reviewer a direct Slack message with the PR title, author, link, and hours waited.
