Can I search for bills in a specific state?

Yes! Use the `get_bill_list` tool and provide the state code (e.g., 'CA' for California, 'NY' for New York). It will return all active bills for the current session.

Does this include the full text of the bills?

The integration currently retrieves bill summaries and status updates. For the full legal text, the tool provides reference links to the official state or federal repositories.

How can I see how my representative voted?

Use the `get_bill_details` tool with the Bill ID. The response includes a roll call section with the results of all votes taken on that specific piece of legislation.
