An attendance management system driven entirely by chat. A LangChain ReAct agent powered by Gemini 2.0 Flash selects tools to register and authenticate users, mark enter/exit/break statuses, prevent duplicates and generate reports. Admins get extra tools such as record deletion and a SQL query tool, with role-based access, SHA-256 password hashing, Pydantic validation and a Gradio UI.
