This example demonstrates how to persist an agent’s session state using a SQLite storage, allowing continuity across multiple runs.
from agno.agent import Agent
from agno.models.openai import OpenAIChat
from agno.storage.sqlite import SqliteStorage
# Define a tool that adds an item to the shopping list
def add_item(agent: Agent, item: str) -> str:
"""Add an item to the shopping list."""
if item not in agent.session_state["shopping_list"]:
agent.session_state["shopping_list"].append(item)
return f"The shopping list is now {agent.session_state['shopping_list']}"
agent = Agent(
model=OpenAIChat(id="gpt-4o-mini"),
# Fix the session id to continue the same session across execution cycles
session_id="fixed_id_for_demo",
# Initialize the session state with an empty shopping list
session_state={"shopping_list": []},
# Add a tool that adds an item to the shopping list
tools=[add_item],
# Store the session state in a SQLite database
storage=SqliteStorage(table_name="agent_sessions", db_file="tmp/data.db"),
# Add the current shopping list from the state in the instructions
instructions="Current shopping list is: {shopping_list}",
# Important: Set `add_state_in_messages=True`
# to make `{shopping_list}` available in the instructions
add_state_in_messages=True,
markdown=True,
)
# Example usage
agent.print_response("What's on my shopping list?", stream=True)
print(f"Session state: {agent.session_state}")
agent.print_response("Add milk, eggs, and bread", stream=True)
print(f"Session state: {agent.session_state}")
