PR Auto-Review

Automated PR review pipeline: code review + service health check + Discord notification. Trigger when a new PR is submitted or when running post-merge validation. Handles: PR diff analysis, CI/CD status check, secret scanning, service health probes, and posting structured results to a Discord channel via webhook. Use phrases: "review this PR", "run PR checks", "auto-review", "PR pipeline", "check PR and notify Discord", "post-merge health check".

Automated pipeline that runs when a new PR is submitted:

1. Code Review — fetch PR diff, check CI/CD status, scan for secrets, list changed files
2. Health Check — verify service availability (uses healthcheck skill if present, falls back to curl probes)
3. Discord Notification — post structured results to a team channel

Quick Start

# Review a GitHub PR and notify Discord
bash scripts/pr-auto-review.sh \
  --pr-url https://github.com/org/repo/pull/123 \
  --discord-webhook https://discord.com/api/webhooks/.../...

# Review a branch diff
bash scripts/pr-auto-review.sh \
  --branch feature/new-api \
  --discord-webhook https://discord.com/api/webhooks/.../...

# Review last commit, skip health check
bash scripts/pr-auto-review.sh --skip-healthcheck

# Save report to file
bash scripts/pr-auto-review.sh --pr-url ... --report ./review-report.md

Options

Flag	Description
--pr-url <url>	GitHub PR URL (extracts PR number automatically)
--branch <name>	Branch to diff against main/master
--discord-webhook <url>	Discord webhook URL for notification
--skip-healthcheck	Skip service health probes
--report <path>	Save markdown report to file

Pipeline Steps

1. Code Review

• Fetches PR diff via gh CLI
• Reports PR title, author, changed files
• Checks CI/CD status (gh pr checks)
• Scans diff for potential hardcoded secrets (password, token, api_key patterns)

2. Service Health Check

• If the healthcheck skill is installed, runs healthcheck.sh --json
• Otherwise, probes common local services via curl (nginx, api, ollama)
• Reports status per service: ✅ OK / 🟡 Degraded / 🔴 Down

3. Discord Notification

• Posts the report summary to the configured webhook
• Content truncated to 2000 chars (Discord limit)
• For richer embeds, see references/discord-formats.md

Dependencies

• gh CLI (authenticated) — for PR data
• git — for branch diffs
• curl — for health probes and Discord webhook
• jq — for JSON payload construction

Integration with Cron

Set up automatic PR review on a schedule:

# Example: check open PRs every 30 minutes
openclaw cron add --name "pr-review-poll" --every 30m \
  --message "Run pr-auto-review on any new open PRs and notify Discord"

Integration with GitHub Webhooks

For real-time triggering, configure a GitHub webhook to call an endpoint that invokes this skill. The pipeline script accepts --pr-url to target the specific PR.

Output

The script outputs a markdown report to stdout and optionally saves it to a file. The report includes:

• PR metadata (title, author, files)
• CI/CD status summary
• Security scan results
• Service health status
• Actionable summary
