Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

belief-based-marketing scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 165 lines — stays where its author put it; the contents beside it link to each section on GitHub.

<quick_start> Provide these materials for analysis:

  • Offer documents, product descriptions
  • Sales call transcripts, customer reviews
  • FAQs, testimonials, support tickets
  • Social media comments, feedback

I will analyze them to:

  1. Extract existing buyer beliefs (positive and negative)
  2. Identify the "3 M's" - Myths, Mistakes, Misconceptions
  3. Determine required beliefs for conversion
  4. Build belief-shifting content using Pathos, Logos, Ethos
  5. Create sequenced messaging flow from Awareness to Decision </quick_start>
  1. What's the offer? (Product/service/program being sold)
  2. What materials do you have? (Any of: sales pages, transcripts, reviews, testimonials, support tickets, social comments, FAQs)
  3. What's the conversion problem? (Optional - where are you losing prospects?)

I'll extract 80-90% of insights from your materials without adding assumptions.

Thoroughly review all provided materials. Extract and summarize:

  • Recurring patterns: questions, objections, praises, confusions
  • Language used and emotional tones
  • Segmentation signals (beginner vs. advanced, customer types)

Categorize into three buckets:

  1. Customer Interactions (questions from calls/reviews)
  2. Offer Details (features/benefits described)
  3. Feedback Patterns (successes/failures in testimonials)

Output: Bulleted summary with 3-5 examples per category including direct quotes. </step_1>

<step_2> Step 2: Identify Existing Beliefs

Mine inputs for what prospects currently believe about:

  • The problem
  • Solutions in general
  • Your specific offer

Hunt for the "3 M's":

  • Myths - False ideas ("This is too expensive for what it does")
  • Mistakes - Wrong actions (focusing on irrelevant details)
  • Misconceptions - Misunderstandings ("This only works for big businesses")

Assess "chain of beliefs" length:

  • Short (inner circle: already trusting, minimal convincing)
  • Long (outsiders: skeptical, need foundational education)

Generate 15-25 beliefs. Assume prospects are beginners to counter "curse of knowledge."

Output Table:

Belief Type Evidence from Inputs Journey Stage Impact on Conversion
</step_2>

<step_3> Step 3: Determine Required Beliefs

For each existing belief, reframe: "What must the prospect believe instead for this to be an obvious, irresistible choice?"

Use the "ladder of importance":

  1. Start with foundational beliefs (problem existence)
  2. Build to advanced beliefs (your unique edge)

Address alternatives/competitors mentioned in inputs.

Output Table:

Existing Belief Required Belief Rationale Journey Stage Priority
</step_3>

<step_4> Step 4: Build the Necessary Beliefs

Develop targeted content using Aristotle's persuasion modes:

  • Pathos (Emotional Appeal): Relatable stories, testimonials evoking desire/fear
  • Logos (Logical Proof): Data, stats, comparisons, demos
  • Ethos (Credibility): Authority builders, credentials, social proof

Tailor intensity:

  • Short chains: Focus on decision-stage trust
  • Long chains: Build from basics

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
