2. Why is it required?

At the moment the agents run in auto-pilot mode and the user is not able to modify/fine-tune the requirements before the task is completed by the agents. This feature is to create a specification file for the coding agent. The specification file can be modified by the user and once the specification file is approved, the coding and reviewer agents kick in to implement the code changes.
