- Matt says Grill Me is not for every task. It is for work that is large and expensive to undo if the agent gets it wrong.
1:12:56 - Upfront alignment matters when bad early code would stay in the context window and shape later work.
1:12:56 - Tiny changes, such as a small bug fix or moving a button a few pixels, do not need a grilling session.
1:13:26 - Matt has a workflow where small feedback becomes a GitHub issue, an implement agent fixes it, a review agent checks it, and he aligns after seeing the result.
1:13:52 - The decision rule is: align afterward for small tasks, use Grill Me for substantial single-session work, and use Wayfinder for work spanning multiple sessions.
1:14:39 - Matt distinguishes this from old waterfall by using aggressive prototyping before settling the spec.
1:15:25 - Agents make prototyping cheaper, so teams can build several rough versions, choose one, and iterate before committing.
1:15:48 - The host argues that the real failure mode of waterfall was multi-year planning and implementation, not short planning before short implementation.
1:16:10 - Matt sees agent workflows as closer to agile because cheap labor makes change easier.
