Create the Showcase Agents
==========================
Define the shared PostgreSQL database, pgvector-backed Agno documentation
knowledge, a focused RAG assistant, and a current web-and-finance researcher.
Prerequisites: Postgres on port 5532, OPENAI_API_KEY, and ANTHROPIC_API_KEY
Run: .venvs/demo/bin/python -m cookbook.05_agent_os.24_showcase.demo
Try: ask Agno Assist about AgentOS, or ask Sage for sourced market context
