grill-on-point
Invoke the grill-with-docs skill on the user-supplied document, plan, or rough idea.
Keep its one-at-a-time interactive grilling, but use a high bar before interrupting the user: settle what can be settled by exploring the code and making the obvious call. Bring the user in only for their decision, a blocker, a plan-versus-code contradiction, or terminology only they can define. Treat that as a judgment standard, not a checklist.
