login_in_agent

This agent checks whether a user is new or already registered, querying a user database such as Google BigQuery to verify the registration number. For a first-time user, it invokes the sign_up_agent, which collects user details, generates a unique registration number, and stores the data in BigQuery using save_user_details_tool. For a returning user, it invokes the login_agent, which verifies credentials against stored data.

Once the user is authenticated, it hands control to the nlp_query_agent for public administration queries. It acts as an authentication layer that initializes session context, handles errors, and protects data privacy. It is built for public sector services and reduces misuse or unauthorized access to sensitive government workflows while improving user tracking and analytics.
