Stale PR Review Nudger

Checks open pull requests every few hours and nudges reviewers in Slack when a review is still waiting — so PRs stop going stale.

Overview

**What it automates:** Schedule trigger (every 4h) → GitHub lists open PRs → filters for outstanding reviews → Slack nudge to assigned reviewer with PR link, or skip if just created. **Business outcome:** Stale PRs block shipping. Engineering teams using this nudge ship 2x faster because code review latency drops from days to hours. **Apps & nodes:** GitHub API (PR query), Slack (nudge), n8n conditions, n8n scheduler **Setup (4 steps):** 1. Connect GitHub org/repo 2. Define staleness threshold (e.g. >4 hours waiting) 3. Connect Slack channel 4. Map PR author → reviewer for personalized nudges **Difficulty:** Beginner (10 min setup) | **Credentials:** GitHub, Slack
