This example demonstrates how to use session summaries with context references, enabling the agent to maintain conversation context and reference previous session summaries.

"""
This example shows how to use the `add_session_summary_to_context` parameter in the Agent config to
add session summaries to the Agent context.

Start the postgres db locally on Docker by running: cookbook/scripts/run_pgvector.sh

from agno.agent.agent import Agent
from agno.db.postgres import PostgresDb
from agno.models.openai import OpenAIChat

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

db = PostgresDb(db_url=db_url, session_table="sessions")

agent = Agent(
    model=OpenAIChat(id="gpt-5-mini"),
    db=db,
    session_id="session_summary",
    enable_session_summaries=True,
)

# 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.",
)

# You can use existing session summaries from session storage without creating or updating any new ones.
agent = Agent(
    model=OpenAIChat(id="gpt-5-mini"),
    db=db,
    session_id="session_summary",
    add_session_summary_to_context=True,

agent.print_response("I also like to play basketball.")

# Alternatively, you can create a new session summary without adding the session summary to context.

# agent = Agent(
#     model=OpenAIChat(id="gpt-5-mini"),
#     db=db,
#     session_id="session_summary",
