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.

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 | $0.00028 | $0.01675 |
| Opus 5 | $0.00014 | $0.00838 |
| Sonnet 5 | $0.00006 | $0.00335 |
| Haiku 4.5 | $0.00003 | $0.00168 |
Grade A, and why
lander-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 10d 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.

Purpose
Generate complete landing page copy structured around RMBC principles. Landing pages are where traffic converts — every element must earn its place. Mobile-first is non-negotiable: 80-90% of DTC traffic arrives on phones. This skill outputs full page copy with section-by-section structure, ready for a designer or page builder. Enforces value-comparison pricing (anchor high, reveal real price as contrast) and includes all conversion elements: social proof, guarantee, FAQ, and multiple CTAs.
Inputs
| Input | Required | Description |
|---|---|---|
product_description |
Yes | What the product is, what it does, key features/ingredients/components |
target_audience |
Yes | Who the prospect is — demographics, pain points, desires, sophistication level |
price_point |
Yes | Product price, payment plans, and any discounts |
traffic_source |
Yes | Where traffic comes from: paid_social, native, search, email, organic |
key_mechanism |
Yes | The product's unique mechanism (output from /mechanism-ideation) |
guarantee |
No | Money-back guarantee details (default: assume 60-day guarantee) |
proof_points |
No | Testimonials, reviews, clinical data, media mentions |
page_type |
No | One of: long_form (full sales page), short_form (squeeze/lead gen), hybrid (default: long_form) |
Execution Protocol
Step 1 — Load Framework Context
Read rmbc-context/SKILL.md to load RMBC framework definitions. Landing pages deploy RMBC in a scrollable format — each section maps to a phase: Research informs audience targeting and proof selection, Mechanism drives the core value proposition, Brief structures the page architecture, Copy executes each section.
Step 2 — Define Page Architecture
Map sections based on page_type:
Long Form (Full Sales Page)
| Section | Mobile Screens | Purpose |
|---|---|---|
| Hero | 1 | Headline + subhead + CTA + hero image |
| Problem | 1-2 | Agitate pain, build urgency |
| Failed Solutions | 1 | Disqualify alternatives |
| Mechanism Reveal | 2-3 | Introduce unique mechanism with visual |
| Features → Benefits | 2-3 | Translate features into outcomes |
| Social Proof Block 1 | 1-2 | Testimonials or case studies |
| Value Stack | 1-2 | List everything they get with anchor pricing |
| Price Reveal | 1 | Contrast anchor vs actual price |
| Guarantee | 1 | Risk reversal |
| Social Proof Block 2 | 1 | Additional proof (different type from Block 1) |
| FAQ | 1-2 | Handle remaining objections |
| Final CTA | 1 | Restate offer, guarantee, urgency |
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.

lander-copy is a skill published in the GitHub repository coleschaffer/copywritingskills-rmbc (30 stars, last pushed 5mo ago), licensed MIT. It adds 28 tokens to every session and 1,675 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
