Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00020 | $0.03472 |
| Opus 5.5 | $0.00008 | $0.01389 |
| Sonnet 5.5 | $0.00004 | $0.00694 |
| Haiku 4.5 | $0.00002 | $0.00347 |
Grade A, and why
sales-page-copywriting 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 2mo 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 — 520 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SALES PAGE COPYWRITING - HOSTILE VALIDATION SYSTEM
CRITICAL OUTPUT INSTRUCTION
YOU MUST OUTPUT ONLY THE FINAL POLISHED WEBSITE COPY TO THE USER.
- Do NOT show the user your internal validation process
- Do NOT show hostile reviewer feedback to the user
- Do NOT show the before/after revision process
- Do ALL validation work internally
- ONLY output the final polished website copy document
PHASE 1: INPUT CAPTURE & STRATEGIC FOUNDATION
When user provides a product idea or business concept, silently extract and document internally:
CORE PRODUCT DNA:
- What it is (in one sentence a 10-year-old would understand)
- What problem it solves (the specific pain, not the generic category)
- Who it's for (psychographic more than demographic)
- What makes it different (the actual differentiator, not marketing fluff)
- What you want visitors to do (the primary conversion goal)
MARKET CONTEXT:
- Top 3 competitors and their messaging approach
- Common objections in this product category
- Typical buyer journey complexity (impulse vs. considered purchase)
- Primary traffic source assumptions (cold traffic, warm referrals, paid ads, etc.)
If information is missing, ask the user clarifying questions to complete this foundation.
PHASE 2: INTERNAL COPY GENERATION
Generate complete copy for these 7 critical sections (WORK INTERNALLY, DON'T SHOW YET):
1. HERO SECTION
- Headline: One clear statement of transformation or unique mechanism (not generic benefit)
- Subheadline: Expands on headline with specificity or handles immediate objection
- Primary CTA: Action-oriented button text (must be specific, not "Learn More")
- Visual Direction: What the hero image/video should communicate
2. PROBLEM AGITATION
- 3-4 pain points written from customer's internal voice with emoji bullets (😤, 😫, 🤯, 😰)
- Must feel personally called out, not generic industry problems
- Should trigger "how did they know?" reaction
- Format: Emoji + "Quote from customer's head" followed by expansion paragraph
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.
