from agno.agent.agent import Agent
from agno.db.postgres import PostgresDb
from agno.models.cohere import Cohere

# ---------------------------------------------------------------------------
# Create Agent

db_url = "postgresql+psycopg://ai:ai@localhost:5532/ai"
agent = Agent(
    model=Cohere(id="command-a-03-2025"),
    # Store agent sessions in a database
    db=PostgresDb(db_url=db_url),
