# Learning Demo: Shared Agent

> Requires the pgvector container: ./cookbook/scripts/run_pgvector.sh.

```python agents.py theme={null}

Learning Demo: Shared Agent
===========================
A single ops assistant with every learning store enabled:

- User Profile: structured fields (name, role, preferences)
- User Memory: unstructured observations about the user
- Session Context: a running summary of each session
- Entity Memory: facts, events, and relationships about external things
- Learned Knowledge: insights that transfer across users (pgvector)
- Decision Log: significant decisions with reasoning

Requires the pgvector container:
    ./cookbook/scripts/run_pgvector.sh
