-This skill is invoked when a loose idea requires more than one agent session to turn into a plan. It creates a stateful decision map in a markdown file, and drives the user through a sequence of tickets to resolve the open questions - which may require either sketching, research or grilling. The map is domain-agnostic: it plans engineering work, course content, or anything else that fits the same shape.

 There are three types of tickets:
 
 - **Research**: Reading documentation, third-party API's, or local resources like knowledge bases. Creates a markdown summary as an asset. Use this when knowledge outside the current working directory is required.
-- **Sketch**: Raise the fidelity of the discussion by making a cheap, rough, concrete artifact to react to — an outline, a rough take, a stub, or UI/logic code via the /prototype skill. Creates the sketch as an asset. Use this when "how should it look" or "how should it behave" is the key question.

 **No open tickets remain.** The fog is pushed back far enough that the path to the finish line is clear — the map is done. (The initial grilling may also surface no fog at all, in which case there was never a map to build.) Recommend implementing directly, or using `/to-prd` to schedule a multi-session implementation.
