tg-user-in-the-loop

Asynchronous user-in-the-loop mechanisms manage clarifying questions by sending blocking or non-blocking prompts via the Telegram bot, allowing background task progression to continue safely while waiting for user input.

Timeout handling for unanswered questions uses a ping schedule at 5, 10, and 15 minutes. If the user remains unresponsive, the bot executes predefined default actions or cancels the task entirely to prevent hanging.

Blocking questions in async task execution halt progress until the user responds, whereas non-blocking questions act as notes that capture user input while allowing the Telegram bot task to continue processing uninterrupted.

You can set default actions for a Telegram bot. When a user fails to respond to a blocking question after a defined timeout period, the user-in-the-loop mechanism automatically proceeds with defaults or cancels the task.

You need a user-in-the-loop mechanism when task execution requires critical user input to prevent failure, such as deciding between two document processing options and needing a safe interactive progression path.
