Overview

A collection of agentic AI workflows built on n8n that automate repetitive developer tasks — from PR code review to deployment notifications and incident triage.

Workflows Included

1. Automated Code Review Agent

  • Triggers on GitHub Pull Request events
  • Sends diff to GPT-4o for analysis
  • Posts structured review comments directly on the PR
  • Flags security issues, performance concerns, and style violations

2. Deploy & Notify Pipeline

  • Watches main branch for merged PRs
  • Triggers Azure deployment pipeline
  • Sends Slack/Teams notification with deployment status
  • Auto-rolls back on health check failure

3. Incident Triage Bot

  • Monitors application logs via webhook
  • Classifies severity using LLM analysis
  • Creates Jira tickets with suggested resolution steps
  • Escalates critical issues to on-call via PagerDuty
