Automate GitHub PR Review: Approve/Request Changes with Slack Alerts

Introduction

Speed up code reviews and keep everyone aligned. This workflow scores a pull request, decides Approve or Request Changes, alerts your team, and stores the results ✅

Trigger Event

When a pull request is ready for review (new or updated) or when you run this flow on a specific PR number.

Actions

• Pull the PR’s file changes from GitHub so the flow knows exactly what changed.
• Check your review/metrics table to find the matching task or developer record for this PR.
• Enrich the file list with any detected to‑dos and send it for AI analysis to produce a structured review.
• Optionally wait a short time to let checks complete, then keep a brief summary in workspace memory.
• Calculate a review decision (Approve or Reject) with a numeric rating and clear reasons.
• If required test identifiers are present, post a helpful message in your team’s Slack channel so reviewers see context immediately.
• If the decision is Approve, submit an approval review on GitHub.
• If the decision is Reject, generate a markdown summary of reasons and submit a “Request changes” review on GitHub.
• If no clear decision is reached, send a Slack DM to prompt a human follow‑up.
• Optionally fetch commit details and compute a final score combining rating, decision, and any prior rejections.
• Update your table:
  • If a matching row exists: increment the rejection count on rejects, and store AI review, rating, task link, and final score.
  • If no row exists: create a new record with the PR number, decision, rating, reasons, and score.
• Save the final summary in memory and optionally clear any temporary knowledge records.

Benefits

• Faster reviews with consistent, AI‑assisted decisions
• Automatic GitHub approvals/requests reduce manual steps
• Slack alerts keep the team informed instantly
• Centralized recordkeeping: save decisions, ratings, and scores in your table
• Fewer missed checks and clearer feedback for contributors
