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.
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.

If the spine sounds like the signal doc rephrased, the reduction did not happen. Push back, or strengthen source briefs and rerun step 01 first.
Watch for "comprehensive solution," "powerful platform," and other category-default phrases sneaking into the spine. The spine should be in the product's own voice as much as possible. See ../pagekit/references/anti-slop.md.
After the spine is in place, invoke pagekit-first-page-decision (step 03). Do not stop here.
