description: Draft or review framework-independent landing-page structure and conversion copy for one primary action.

## Goal

Produce one evidence-backed landing-page draft, targeted rewrite, or review for one audience and primary action. Publishing and experiments remain external.

### Definition of Done

- The requested draft, rewrite, or review is delivered for the stated audience and action.
- Claims, assumptions, evidence gaps, and the conversion path are explicit.
- Review findings include evidence, a correction, and an acceptance check.
- Current validation accepts the selected mode; an unmet required criterion remains REVISE or BLOCKED.

## Boundaries

- Do not invent testimonials, metrics, guarantees, customer claims, or observed experiment results. Mark them as missing or use supported evidence.

## Workflow

1. Resolve the mode, audience, action, outcome, evidence, and acceptance criteria from the request, applicable instructions, and loaded principles.
2. Use [Structure blueprints](references/structure-blueprints.md) for page architecture, [Copywriting formulas](references/copywriting-formulas.md) for drafting or rewriting, and [Review rubric](references/review-rubric.md) for assessments. Draft one recommended conversion path, or return evidence-backed findings with replacement copy.
3. Check claims against available evidence and record material assumptions and gaps.
4. For substantive work, use [Quality validation](references/vstack/protocols/quality-validation.md), passing the mode, scope, candidate, and evidence; otherwise apply its self-assess, review, critique, triage, improve, and renewed-verdict loop directly. Repair only the authorized output until the current candidate passes.
5. Return the result, current evidence, and the unmet criterion with its next action when validation cannot pass.
