Does anyone know any github repo or web forum where it is explained/implemented something similar like an AI agent in langchain/langgraph capable of getting information from a customer database. The idea would be something like: you ask the bot "Hey Im Michael" and then it aks you for a password. When the agent authorizes you, then you can ask it like "I would like you to send me an email with the last 5 invoices summarized in a csv file". For that query, the agent has to start a thinking chain where it would first identify the purpose of the user, then go to the database and take the invoices as a tool, use another tool to summarize all that information, and the final use a final tool which sends the information back to the user via email. Does someone know any similar project on Internet where I can see the source code? Thanks in advance.
