Look up what the record, the repo, or the world can answer. Only what the user alone holds routes to a skill.

Route each thing still left to invent by what it is, invoking the named skill with the Skill tool:

• The words admit two readings that would build different things → use clarify skill.
• The user holds what they want but can't yet say it → use elicit skill.
• The user is missing something already settled and can't ask past it → use explain skill.
• The ask arrives committed, its decisions undefended → use interrogate skill.
• The ask names a step or an artifact and leaves the outcome it serves unnamed — the same kind of task keeps coming, or the artifact exists to inform a decision → use reframe skill before asking what it is for.

Route again until nothing is left to invent.

Ask what is still open first, with AskUserQuestion. A restated ask is the user's to take: offer it beside the ask as given. Before rewriting the ask, use deepen skill on it. Then state the work order, naming no skill: the ask, the bar it must meet, and what it must NOT do where that surfaced. As short as it goes with nothing in the spec lost.

The WHAT is confirmed and what's open is the technical path → use shape skill.
