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 | $0.00036 | $0.01782 |
| Opus 5 | $0.00018 | $0.00891 |
| Sonnet 5 | $0.00007 | $0.00356 |
| Haiku 4.5 | $0.00004 | $0.00178 |
Grade A, and why
broadcast-email 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.
How it starts
The opening of the file, as written. The whole thing — 179 lines — stays where its author put it; the contents beside it link to each section on GitHub.
broadcast-email
Purpose
Generate standalone broadcast emails for ongoing list engagement. Unlike sequences, broadcasts are one-off sends that keep the list warm, build authority, and drive revenue between automated flows. Each broadcast type serves a different strategic purpose — content emails build trust, story emails build connection, controversy emails drive engagement, case studies build proof, and flash promos drive immediate revenue. This skill produces complete email copy with 3 subject line variants, preview text, body, CTA, and PS line.
Inputs
| Input | Required | Description |
|---|---|---|
email_type |
Yes | One of: content, story, controversy, case_study, flash_promo |
topic |
Yes | The specific topic, story, hot take, case study, or promotion |
target_audience |
Yes | Who the reader is — demographics, pain points, desires |
product_mention |
No | Product to reference or link to (omit for pure engagement emails) |
brand_voice |
No | One of: founder, expert, friend, provocateur (default: founder) |
Execution Protocol
Step 1 — Load Framework Context
Read rmbc-context/SKILL.md to load RMBC framework definitions. Broadcasts deploy RMBC in single-email format — Research drives topic relevance, Mechanism adds unique insight, Brief selects the angle, Copy executes with clarity and impact.
Step 2 — Select Structure by Type
| Type | Structure | Tone | Length | CTA Style |
|---|---|---|---|---|
| Content | Teach one thing → actionable takeaway → optional product bridge | Educational, generous | 400-600 words | Soft: "Try this today" or link to resource |
| Story | Scene → tension → resolution → lesson → bridge | Conversational, personal | 350-500 words | Soft: reply, share, or subtle product link |
| Controversy | Hot take → evidence → "here's what most people get wrong" → reframe | Bold, direct, opinionated | 300-500 words | Engagement: "Reply and tell me if I'm wrong" |
| Case Study | Situation → challenge → what they did → results → lesson | Proof-driven, specific | 400-600 words | Medium: "Want similar results? Here's how" |
| Flash Promo | Offer → reason why now → proof → scarcity → CTA | Urgent, direct | 200-350 words | Hard: "Buy now before midnight" |
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.

broadcast-email is a skill published in the GitHub repository coleschaffer/copywritingskills-rmbc (30 stars, last pushed 5mo ago), licensed MIT. It adds 36 tokens to every session and 1,782 once invoked, about $0.0002 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.
