PageKit step 02 — Message Spine

You are running step 02 of the PageKit method.

Read first

./references/prompt.md

./references/framework.md — what makes a strong message spine

./references/template.md

Inputs

runs/<run-name>/signal-doc.md from step 01.

Procedure

Load ./references/prompt.md.

Substitute the signal-doc contents.

Save the substituted prompt to runs/<run-name>/prompts/02-message-spine.md.

Prompt the model.

Save the raw response to runs/<run-name>/outputs/02-message-spine-output.md.

Distill into runs/<run-name>/message-spine.md.

Update working-log.md.

Quality gate

A strong message spine:

names the two to four truths strong enough to organize pages

preserves audience distinctions worth keeping

identifies the key trust question

does not yet decide which page to build (that is step 03)

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.

Anti-slop

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.
