New to the words? The glossary explains terms like RAG, grounding and eval harness in a paragraph each.
The problem
Fifty thousand internal documents, answers that must cite their source, and an audience that will stop trusting the system after one confident wrong answer.
When you finish
You can draw the retrieval architecture, name the decision you would make differently, run the supervisor code, and audit the system against a threat list.

Problem · step 1 · Explainer
You cannot run RAG on user complaints
Start with what broke. The demo lied politely; this is what the fifty-thousand-document version taught us.
Architecture · step 2 · System
Place RAG in the map. It is one node among six, and the other five decide whether it works.
Decision · step 3 · Deep dive
One MCP server is an integration. Thirty is why you need a gateway
Tools and retrieval both need permissions, identity and audit. This is the gateway decision and its consequences.
Code · step 4
Supervisor Graph with LangGraph
The retrieval node as an explicit graph, with a deterministic supervisor you can test.
Observe · step 5 · Tool
Trace every hop. Retrieval latency and recall only improve once you can see them per request.
Secure · step 6 · Reference
OWASP Top 10 for LLM Applications
Check the finished design against the threat list before it touches production data.
Lessons · step 7 · Architecture pattern
Designing a Multi-Agent System for Real-World Use
What changed once the single RAG agent became a team, and where humans still belong.
