# Message House Builder Derives the launch messaging hierarchy from the positioning canvas — a message house (tagline, one-liner, three value pillars, per-persona proof points), a working-backwards PR-FAQ narrative spine, and per-channel message angle packs. It sits in the **Assemble** phase of the RAMP loop and feeds three [RAMP](../../../references/ramp-benchmark.md)-`A` sub-items: *message house complete*, *narrative spine (PR-FAQ or equivalent) in launch-day tense with numbers over adjectives*, and *announcement ↔ landing ↔ offer message-match*. It is also the upstream of the `A1` claim-integrity veto: every product or comparative claim without substantiation is marked `[needs source]` and submitted to `memory/claims/candidates.md` — this skill never adjudicates a claim. **Scope guard**: this skill turns an existing positioning canvas into messaging only. It does **not** build the positioning itself ([positioning-mapper](../../research/positioning-mapper/SKILL.md) is the sole upstream — if the canvas is missing, route there first and stop), write finished blog posts or pages ([content-writer](../../../seo-geo/build/content-writer/SKILL.md)), produce ad or email units ([ad-creative-builder](../../../ad/orchestrate/ad-creative-builder/SKILL.md) / [email-creative-builder](../../../email/engage/email-creative-builder/SKILL.md)), adjudicate claims ([offer-claims-registry](../../../protocol/offer-claims-registry/SKILL.md) is the sole writer of `memory/claims/claims-ledger.md`...
