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

offer-stack 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 8d 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.

If INTRO_SEEN is no, run the one-time welcome before continuing with this skill:

Welcome to RMBC Skills — Stefan Georgi's direct response copywriting framework, built into Claude Code. 44 skills covering hooks, ads, emails, landing pages, VSL scripts, and more.

Stefan recorded a quick video on why AI is the biggest opportunity in years for DTC marketers, freelancers, and copywriters — and why the people panicking about it are playing a different game than you.

Use AskUserQuestion:

  • Question: "Want to watch Stefan's take on why this is the best time to be in DTC? (~5 min)"
  • Options:
    1. "Sure, open it"
    2. "Maybe later — let's write some copy"

If "Yes, open the video":

open "https://www.youtube.com/watch?v=zI8tNfefH1M"
mkdir -p ~/.rmbc-skills
touch ~/.rmbc-skills/.intro-seen

If "Skip — let's go":

mkdir -p ~/.rmbc-skills
touch ~/.rmbc-skills/.intro-seen

Continue with this skill immediately.

If INTRO_SEEN is yes and TEL_PROMPTED is no: One-time telemetry opt-in:

Help make RMBC Skills better! Usage analytics tracks which skills you run and how often so we can focus on the ones that matter most. Everything stays on your machine — no code, prompts, or file paths leave your computer.

Use AskUserQuestion:

  • Question: "Cool with anonymous usage analytics? You can change this anytime."
  • Options:
    1. "Sure, happy to help" — keep analytics on and mark as prompted
    2. "No thanks" — disable analytics and mark as prompted

If "Yes, that's fine":

mkdir -p ~/.rmbc-skills
touch ~/.rmbc-skills/.telemetry-prompted

If "No, turn it off":

mkdir -p ~/.rmbc-skills
touch ~/.rmbc-skills/.telemetry-prompted
sed -i '' 's/^analytics_enabled:.*/analytics_enabled: false/' ~/.rmbc-skills/config.yaml 2>/dev/null || true
