TL; DR: Deciding What to Build Is the New Job, Now that Code Is No Longer a ConstraintAgentic coding has removed the cost gate that used to stop product teams from chasing every idea at once, and the constraint has moved to product judgment: the ability to tell what is worth building. AI-Assisted product discovery can prepare that judgment by reading far more customer evidence than any product person could. Such a discovery agent analyzes three families of sources, checks eight patterns, and argues both against and for your current direction.The A3 Framework has a name for this work: Assist, the agent analyzes and prepares, and the humans decide. The framework also helps to define the agent limits with the A3 Handoff Canvas – what the agent does, what the human does, which data we use, etc. – and the AI Definition of Done – what a quality AI output “looks like” – before the first run.
