Gently nudge reviewers when a pull request has been waiting more than 48 hours, with smart routing to someone who can actually review it.
Pull requests sometimes sit for days waiting on a review. We want a Slack bot that watches open PRs, and after 48 hours nudges the assigned reviewer — or re-routes to another qualified reviewer based on CODEOWNERS — so nothing quietly rots.
Teams run 3–6 people, including the lead.
