How to Connect GitHub Pull Request Reviews to Slack Using OpenClaw

The Problem with PR Reviews Getting Lost

Pull request reviews are the connective tissue of software delivery. But in a busy engineering org, they routinely fall through the cracks. A senior engineer gets pinged on five PRs, opens Slack, scrolls past the notifications, and by the time they context-switch back, the author has been blocked for three hours.

SlackClaw, powered by OpenClaw, solves this by turning GitHub’s pull request lifecycle into actionable, prioritized Slack messages — and letting your team act on them without leaving Slack.

What OpenClaw Does Under the Hood

OpenClaw is the open-source AI agent framework (145,000+ GitHub stars) at the heart of SlackClaw. It maintains a persistent skill graph per workspace — a set of automations that listen to external events, reason over them, and decide what to surface in Slack. The GitHub integration skill polls or receives webhooks from GitHub, normalizes PR metadata, and hands it off to OpenClaw’s routing layer.

You configure these Skills in plain English. No YAML pipelines, no webhook handler boilerplate.

Step 1: Connect GitHub to SlackClaw

From your SlackClaw workspace, type:

/openclaw connect github

OpenClaw will reply with a GitHub OAuth link. Authorize it with an account that has access to your org’s repositories. Once connected, you’ll see:

GitHub connected. I have read access to 47 repositories in your org.
What would you like me to watch?

You can be granular:

Watch PRs in saroyas/backend and saroyas/api-gateway

Or broad:

Watch all PRs across the org

Step 2: Define Your Review Routing Rules

This is where OpenClaw’s Skills system shines. Instead of writing a webhook handler, you describe what you want in plain English:

When a PR is opened targeting main, notify the #engineering-reviews channel.
Include the author, title, and a link.
If the PR has more than 400 lines changed, add a red label and ping @tech-lead.

OpenClaw compiles this into a persistent rule that fires on every matching event.

Step 3: Act on PRs from Slack

Notifications are only half the equation. OpenClaw lets your team take action without switching tabs:

Approve PR #847 with comment "LGTM — clean implementation"

Request changes on PR #851 — tell them the API endpoint needs input validation

Each of these commands maps to a real GitHub API call. OpenClaw handles the authentication, the API call, and confirms the result in Slack.

Step 4: Daily PR Review Digest

For teams doing async code review across time zones, a morning digest is invaluable:

Every weekday at 9am, post a PR digest to #engineering-reviews.
List all open PRs sorted by age, with reviewer assignment status.

Self-Hosting vs. RunLobster

SlackClaw runs OpenClaw’s agent runtime on a dedicated server per workspace. If you prefer to run OpenClaw yourself, RunLobster offers managed OpenClaw hosting — your own instance in the cloud within 60 seconds.

Why This Beats Native GitHub Notifications

GitHub’s native Slack integration sends you notifications. SlackClaw’s OpenClaw integration lets you act. Less context switching, faster review cycles, and a single place where your team actually works — Slack.
