THE CLAUDE COURSE BOOK — 12 chapters. Zero to production. The step-by-step guide to building an AI Chief of Staff that runs 24/7 for ~$15/month.
Rohan Mukherjee — Building things that matter. Telling stories that people need to hear.
This is the complete build guide. Not theory. Not "prompting tips." The actual step-by-step system I used to go from "I have a Claude account" to "I have 13 autonomous AI systems running 24/7."
You'll build a two-layer AI operating system: an interactive agent (Dracarys) living in Slack + Telegram, and an intelligence engine (Claude Cowork) that scans all your tools and delivers prioritized briefings every morning.
Time to build: ~8 hours. Monthly cost: ~$15-20. ROI: 15+ hours saved per week.
| Component | Tool | Cost |
|---|---|---|
| Interactive Agent | OpenClaw (open-source) | Free |
| LLM API | OpenRouter (Claude Sonnet 4.6) | ~$15-20/month |
| Server | Oracle Cloud Free Tier VPS | Free forever |
| Chat Channels | Slack + Telegram | Free |
| Intelligence Engine | Claude Desktop (Cowork) | Your Claude subscription |
| Task Database | Notion | Free tier |
| Meeting Notes | Granola | Free tier |
You'll need a Claude subscription (Pro or Enterprise), about $20 for API credits, and roughly 8 hours of focused time.
