Run a skeptical claim-check pass on a PageKit first-page draft, at light/normal/hard severity. Step 07 of the PageKit method. Use after a first-page draft exists and you want to validate it before treating it as publishable. Delegates to the pagekit-claim-checker subagent.
Decide which page should exist first for the object, without defaulting to homepage. Step 03 of the PageKit method. Use when the user has a signal doc + message spine and needs to choose the first page, or asks "should this be a homepage?" or "what page should we build first?"
Draft the first page from the full PageKit chain. Step 06 of the PageKit method. Use when steps 01-05 are done and you are ready to write the page itself. The draft must respect the anti-slop drafting constraints.
Reduce a PageKit signal doc into a message spine. Step 02 of the PageKit method. Use when the user asks to "reduce this signal to a spine," "build a message spine," or has finished step 01 and is ready for step 02.
Design the page argument shape — what sections the chosen first page should and should not have. Step 04 of the PageKit method. Use when the first-page decision is made and you need a structure for the draft.
Map proof to the chosen first page section by section. Step 05 of the PageKit method. Use after the page argument shape exists and before drafting.
Build a PageKit signal doc from a product description and any source briefs. Step 01 of the PageKit method. Use when the user asks to "build a signal doc," "extract signal from this material," or is starting a PageKit run on a new object.
Run the full PageKit method end-to-end on an object. Use when the user asks to "run PageKit on X", "build a page for X using PageKit", or "produce a fully-logged PageKit run for X". Orchestrates steps 01-07 (signal doc, message spine, first-page decision, page argument shape, proof map, first-page draft, optional claim-check) and produces a fully-logged run on disk under runs/<name>/.
