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 | $0.00039 | $0.03942 |
| Opus 5 | $0.00019 | $0.01971 |
| Sonnet 5 | $0.00008 | $0.00788 |
| Haiku 4.5 | $0.00004 | $0.00394 |
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 output shows UPGRADE_AVAILABLE <old> <new>: read skills/rmbc-upgrade/SKILL.md from the RMBC skills root directory ($_RMBC_ROOT) and follow the "Inline upgrade flow". If JUST_UPGRADED <old> <new>: read $_RMBC_ROOT/CHANGELOG.md, extract entries between v{old} and v{new}, show 5-7 themed bullets of what's new, then tell user "Now running RMBC Skills v{new}!" and continue.
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:
- "Sure, open it"
- "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:
- "Sure, happy to help" — keep analytics on and mark as prompted
- "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
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.
- 8d ago First seen · 323 lines · 39 tokens per session scan A d32d1d395c84
offer-stack is a skill published in the GitHub repository coleschaffer/dtc-copywriting-skills (24 stars, last pushed 4mo ago), licensed MIT. It adds 39 tokens to every session and 3,942 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.
