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 | $0.00027 | $0.01416 |
| Opus 5 | $0.00014 | $0.00708 |
| Sonnet 5 | $0.00005 | $0.00283 |
| Haiku 4.5 | $0.00003 | $0.00142 |
Grade A, and why
advertorial-writer 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 — 128 lines — stays where its author put it; the contents beside it link to each section on GitHub.
advertorial-writer
Purpose
Generate advertorial copy that looks and feels like editorial content but sells. Advertorials are the bridge between paid traffic and a sales page — the prospect clicks an ad, lands on what looks like a news article or blog post, and by the end they're ready to buy. The key tension: it must feel editorial (not salesy) while still deploying RMBC persuasion structure. Traffic source context matters — native ad platforms (Taboola, Outbrain) have different compliance and style requirements than social traffic.
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 |
angle |
Yes | The editorial angle — the "news peg" or story that frames the product (e.g., "new study reveals...", "local mom discovers...") |
traffic_source |
Yes | One of: native (Taboola/Outbrain), facebook, google, email, organic |
key_mechanism |
No | The product's unique mechanism (output from /mechanism-ideation) |
tone |
No | One of: news, personal_story, investigative, listicle (default: personal_story) |
Execution Protocol
Step 1 — Load Framework Context
Read rmbc-context/SKILL.md to load RMBC framework definitions. Advertorials deploy RMBC through an editorial lens — the Research phase becomes "reporting," the Mechanism becomes the "discovery," and the Brief structures the narrative arc.
Step 2 — Select Advertorial Format
Based on tone input:
| Format | Structure | Best For |
|---|---|---|
| News | Headline → dateline → discovery → expert quotes → mechanism → product mention → CTA | Health, finance, tech |
| Personal Story | "I" narrative → problem → failed attempts → discovery → results → recommendation | Weight loss, beauty, self-improvement |
| Investigative | Question headline → industry exposé → hidden truth → mechanism → solution → CTA | Supplements, skincare, finance |
| Listicle | Number headline → tips/facts → mechanism woven in → product as #1 solution → CTA | Broad audiences, social traffic |
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.

advertorial-writer is a skill published in the GitHub repository coleschaffer/copywritingskills-rmbc (30 stars, last pushed 5mo ago), licensed MIT. It adds 27 tokens to every session and 1,416 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.
