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 | $0.01456 |
| Opus 5 | $0.00014 | $0.00728 |
| Sonnet 5 | $0.00006 | $0.00291 |
| Haiku 4.5 | $0.00003 | $0.00146 |
Grade A, and why
vsl-script 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 7d 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 — 138 lines — stays where its author put it; the contents beside it link to each section on GitHub.
vsl-script
Purpose
Generate a complete VSL (Video Sales Letter) script structured around RMBC principles. VSLs are the highest-converting long-form format in direct response — they combine the persuasive power of long-form copy with the engagement of video. Every VSL follows the same proven arc: hook → problem → mechanism reveal → proof cascade → offer → close. Scripts include timing markers so the client or editor knows pacing at a glance. Mobile-first: 80%+ of VSL viewers watch on phones.
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 |
key_mechanism |
Yes | The product's unique mechanism (output from /mechanism-ideation) |
price_point |
Yes | Product price and any payment plan options |
guarantee |
Yes | Money-back guarantee details (duration, conditions) |
proof_points |
No | Testimonials, case studies, clinical data, expert endorsements |
target_length |
No | One of: short (10-15 min), standard (25-35 min), long (45-60 min). Default: standard |
Execution Protocol
Step 1 — Load Framework Context
Read rmbc-context/SKILL.md to load RMBC framework definitions. VSLs deploy all four RMBC phases sequentially — Research informs the hook and problem section, Mechanism drives the core revelation, Brief structures the argument, Copy executes the persuasion.
Step 2 — Map the VSL Arc
Build a structural outline with timing markers before writing:
| Section | Timing (standard) | Purpose |
|---|---|---|
| Hook | 0:00–0:30 | Stop the scroll, open a loop |
| Problem Agitation | 0:30–3:00 | Make the pain vivid and urgent |
| Failed Solutions | 3:00–5:00 | Disqualify alternatives |
| Mechanism Reveal | 5:00–10:00 | Introduce the unique mechanism |
| Proof Cascade | 10:00–18:00 | Stack evidence — testimonials, data, demos |
| Product Introduction | 18:00–22:00 | Bridge mechanism to product |
| Offer Stack | 22:00–27:00 | Value stack with price anchoring |
| Risk Reversal | 27:00–29:00 | Guarantee removes objection |
| Close + Urgency | 29:00–32:00 | Final CTA with scarcity/urgency |
| PS / Second Close | 32:00–35:00 | Recap for skimmers, restate guarantee |
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.

vsl-script 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 1,456 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.
