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.

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.
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.

./references/prompt.md./references/framework.md./references/template.md../pagekit/references/anti-slop.md — the drafting constraints the shape produces must include the anti-slop rulesruns/<run-name>/first-page-decision.mdruns/<run-name>/message-spine.md (for context)./references/prompt.md.runs/<run-name>/prompts/04-page-argument-shape.md.runs/<run-name>/outputs/04-page-argument-shape-output.md.runs/<run-name>/page-argument-shape.md. Make sure the drafting-constraints section includes the anti-slop block from ./references/template.md.working-log.md.A strong page argument shape:
The shape's drafting-constraints section is where slop prevention starts. If those constraints are missing or watered down, every step downstream is weaker.
After the shape is in place, invoke pagekit-proof-map (step 05). Do not stop here.
