What This Is

A hands-on course where you collaborate with Claude Code to build a full-featured RAG system. You're not the one writing code—Claude is. Your job is to guide it, understand what you're building, and course-correct when needed.

You don't need to know how to code. You do need to be technically minded and willing to learn about APIs, databases, and system architecture.

What You'll Build

• Chat interface with threaded conversations, streaming, tool calls, and subagent reasoning
• Document ingestion with drag-and-drop upload and processing status
• Full RAG pipeline: chunking, embedding, hybrid search, reranking
• Agentic patterns: text-to-SQL, web search, subagents with isolated context

Tech Stack

| Layer | Tech | |-------|------| | Frontend | React, TypeScript, Tailwind, shadcn/ui, Vite | | Backend | Python, FastAPI | | Database | Supabase (Postgres + pgvector + Auth + Storage) | | Doc Processing | Docling | | AI Models | Local (LM Studio) or Cloud (OpenAI, OpenRouter) | | Observability | LangSmith |

The 8 Modules

1. App Shell — Auth, chat UI, managed RAG with OpenAI Responses API
2. BYO Retrieval + Memory — Ingestion, pgvector, switch to generic completions API
3. Record Manager — Content hashing, deduplication
4. Metadata Extraction — LLM-extracted metadata, filtered retrieval
5. Multi-Format Support — PDF, DOCX, HTML, Markdown via Docling
6. Hybrid Search & Reranking — Keyword + vector search, RRF, reranking
7. Additional Tools — Text-to-SQL, web search fallback
8. Subagents — Isolated context, document analysis delegation

Getting Started

1. Clone this repo
2. Install Claude Code
3. Open in your IDE (Cursor, VS Code, etc.)
4. Run claude in the terminal
5. Use the /onboard command to get started
