This example shows how to use the add_session_summary_references parameter in the Agent config to add references to the session summaries to the Agent.

​
Code

from agno.agent.agent import Agent
from agno.memory.v2.db.postgres import PostgresMemoryDb
from agno.memory.v2.memory import Memory
from agno.models.google.gemini import Gemini
from agno.storage.postgres import PostgresStorage

db_url = "postgresql+psycopg://ai:ai@localhost:5532/ai"

memory_db = PostgresMemoryDb(table_name="memory", db_url=db_url)

# Reset for this example
memory_db.clear()

memory = Memory(db=memory_db)

user_id = "john_doe@example.com"
session_id = "session_summaries"

agent = Agent(
    model=Gemini(id="gemini-2.0-flash-exp"),
    memory=memory,
    storage=PostgresStorage(table_name="agent_sessions", db_url=db_url),
    enable_session_summaries=True,
    session_id=session_id,
)

# This will create a new session summary
agent.print_response(
    "My name is John Doe and I like to hike in the mountains on weekends.",
    user_id=user_id,
)

# You can use existing session summaries from session storage without creating or updating any new ones.
agent = Agent(
    model=Gemini(id="gemini-2.0-flash-exp"),
    memory=memory,
    storage=PostgresStorage(table_name="agent_sessions", db_url=db_url),
    add_session_summary_references=True,
    session_id=session_id,
)

agent.print_response("What are my hobbies?", user_id=user_id)
