What its author says it does

Copied from the file, not written here

Audit or, when authorized, rewrite persuasive product claims against shipped-product evidence. Use for landing pages, marketing-heavy READMEs, feature or pricing pages, comparisons, and calls to action.

Marketing Claims Review

Own claim substantiation, positioning, comparisons, and first-visitor clarity regardless of file location.

Workflow

  1. Confirm pages, audience, and audit-only or authorized rewrite mode.
  2. Build a capability map with implementation and runtime evidence taking precedence over marketing prose, demos, and roadmap material.
  3. Classify material claims as accurate, unclear, unsupported, exaggerated, stale, or false.
  4. Test whether a first-time visitor can identify the product, intended user, problem, mechanism, difference, limitations, and next action.
  5. For each problematic claim, cite evidence and recommend keep, rewrite, move, remove, qualify, or prove.
  6. Rewrite only when authorized, preserving distinctions between shipped, partial, experimental, planned, and unsupported behavior.
  7. After an authorized rewrite, use english-text-review and apply material findings without weakening substantiation, necessary qualifications, or intentional voice.

Use docs-review for repository-document structure and discoverability, and docs-drift-review only for drift caused by the current change. Comparative claims requiring external competitor evidence remain unverified unless authoritative evidence is available and its use is authorized.

Do not infer capabilities from aspirations, invent proof, or force parallel agents.

Finish with scoped claims, evidence, dispositions, authorized edits, and unresolved proof needs.
