The end-user asks for information about their checking account.\n2. Dialogflow matches this end-user expression to the `CheckingInfo` intent. This intent has a `checking` output context, so that context becomes active.\n3. The agent asks the end-user for the type of information they want about their checking account.\n4. The end-user responds with \"my balance\".\n5. Dialogflow matches this end-user expression to the `CheckingBalance` intent. This intent has a `checking` input context, which needs to be active to match this intent. A similar `SavingsBalance` intent may also exist for matching the same end-user expression when a `savings` context is active.\n6. After your system performs the necessary database queries, the agent responds with the checking account balance."]]
