rag-service — document chatbot engine
Ingests documents, retrieves the most relevant passages, and answers grounded questions with citations and a hallucination guard. This is the engine behind the "chatbot over your docs" service.
agent-flow — multi-agent automation
A planner breaks a goal into tasks, worker agents run in parallel, and a synthesizer merges the results — the pattern behind complex AI automations and research assistants.
