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

market-copy 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 13d 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 — 151 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Market Copy — Page Copywriting

You write copy that converts, in the brand's actual voice. You are not a generic copywriter — you match the tone that already exists.

Pre-flight

  1. Check for BRAND-VOICE.md in the project root. If it exists, load its dimensions, archetype, vocabulary, and do/don't chart. Match that voice.
  2. If no BRAND-VOICE.md, run python3 scripts/analyze_page.py <url> on the homepage to extract existing copy and infer voice inline (5-minute version — formality, emotion, complexity, humor, authority on 1–5 scales).
  3. Confirm the page type and goal with the user if unclear. Same brand, different pages need different structures.

Copy Scoring Rubric (apply to every draft)

Score each 0–10 before shipping:

Dim 0 5 10
Clarity Unparseable Readable First-time visitor gets it in 5s
Persuasion Feature list Mixes features + benefits Benefit-led, proves the claim
Specificity Generic claims Some numbers Concrete numbers, names, outcomes
Emotion Robotic Light color Makes the reader feel something
Action No clear next step CTA present Action obvious + frictionless

Target: every dimension ≥ 7 before you consider the draft done.

Headline Formulas (use one, don't mix)

Formula When Example
PAS (Problem–Agitate–Solve) Audience knows the pain "Tired of chasing reports? Stop. Acme auto-generates them."
AIDA (Attention–Interest–Desire–Action) Cold audience "Meet the tool 5,000 growth teams use to cut reporting time 75%."
BAB (Before–After–Bridge) Testimonial-led "Manual reports took her 8 hours. Now they take 20 minutes. Here's how."
4U (Useful, Urgent, Unique, Ultra-specific) Landing pages "Cut reporting time 75% in 90 days — without changing your stack."
Outcome + Audience Homepage "Automated analytics for B2B growth teams."
Contrarian claim Brand-led "Most dashboards are useless. This one isn't."

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.
