CPY-004 Context default layer: section

Mechanism explains the promise

IF the promise is unfamiliar, counterintuitive, or in a sophisticated market, THEN explain why and how the offer produces the result ELSE keep the mechanism concise.

Why the rule exists

A mechanism converts a bare claim into an understandable causal story.

Condition

The rule fires when this evaluates true. Paths marked below must be present in the fact base; the engine reports the rest rather than guessing them.

  • ANY
    • copy.promise.familiarity eq "low"
    • copy.promise.counterintuitive eq true
    • market.sophistication in [high, very_high]

Facts this rule reads

PathSource
copy.promise.familiarity You supply it
copy.promise.counterintuitive You supply it
market.sophistication You supply it

Then

  1. insert — target copy.mechanism

Else

  1. retain — target current_text, No triggering condition is present.

Other copywriting rules

  1. CPY-001 Start from market awareness IF writing persuasive copy, THEN classify the audience as unaware, problem-aware, solution-aware, product-aware, or most-aware before choosing the message ELSE request research. Hard constraint
  2. CPY-002 Match lead to awareness and evidence IF awareness is known, THEN select a lead type that bridges the reader’s current state to the offer ELSE do not default to a hype lead. Context default
  3. CPY-003 Headline makes one credible promise IF a headline is used, THEN make its audience relevance, benefit or curiosity, and credible scope legible ELSE revise. Hard constraint
  4. CPY-005 Translate feature into buyer outcome IF copy names a feature, THEN connect it to functional benefit, practical outcome, and relevant emotional meaning when supported ELSE remove the feature. Context default
  5. CPY-006 Specificity earns credibility IF a claim uses generic superiority language AND verifiable specifics exist, THEN replace the generic phrase with the relevant specific ELSE qualify or remove it. Heuristic
  6. CPY-007 Proof appears after or near the claim IF a material sales claim is made, THEN attach the strongest appropriate proof close to it ELSE weaken or remove the claim. Hard constraint
  7. CPY-008 Testimonial is real, typicality-aware, and specific IF a testimonial is used, THEN verify identity permission, authenticity, result context, and any required typicality disclosure ELSE remove it. Hard constraint
  8. CPY-009 Objection response names the real risk IF research shows a recurring material objection, THEN acknowledge it, answer with proof or terms, and preserve any legitimate limitation ELSE do not invent objections. Context default
