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 | $0.00047 | $0.02040 |
| Opus 5 | $0.00023 | $0.01020 |
| Sonnet 5 | $0.00009 | $0.00408 |
| Haiku 4.5 | $0.00005 | $0.00204 |
Grade A, and why
guarantee-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.

guarantee-writer
Purpose
Generate risk-reversal guarantees that convert fence-sitters into buyers. The guarantee is the most underrated conversion element in direct response — it doesn't just reduce risk, it demonstrates confidence in your mechanism. A strong guarantee says "we believe in our [mechanism] so much that we'll put our money where our mouth is." This skill produces 3 guarantee options across different types, each with a headline, terms, visual treatment suggestion, and copy ready for the checkout page, sales page, and email.
Inputs
| Input | Required | Description |
|---|---|---|
product_name |
Yes | Product name and brief description of what it delivers |
price_point |
Yes | Price — affects guarantee framing (higher price = stronger guarantee needed) |
guarantee_type |
Yes | One of: money_back, conditional, better_than_money_back, double_money_back, performance_based, or all to generate one of each |
guarantee_duration |
Yes | How long the guarantee lasts: 30, 60, 90, 365 days, or lifetime |
target_audience |
Yes | Who the buyer is — their risk tolerance, sophistication, past experiences with guarantees |
Execution Protocol
Step 1 — Load Framework Context
Read rmbc-context/SKILL.md to load RMBC framework definitions. The guarantee is a Mechanism expression — it proves you believe in your own "why it works" story. Research reveals what risks the audience fears most. The Brief determines how aggressively to position the guarantee. Copy executes the guarantee language to feel confident, not defensive.
Step 2 — Diagnose the Risk Profile
Before writing, understand what's actually at stake for the buyer:
| Risk Type | Question | Impact on Guarantee |
|---|---|---|
| Financial | Can they afford to lose this money? | Higher price = longer duration, stronger terms |
| Results | Do they believe the product will work? | Results skepticism = conditional or performance guarantee |
| Trust | Do they trust the company to honor the guarantee? | Low trust = simple process, no fine print, well-known payment processor |
| Effort | Will they have to work hard to get a refund? | Friction fear = "no questions asked" + clear process |
| Social | Will they feel foolish if it doesn't work? | Ego risk = frame guarantee as "smart insurance" not "safety net" |
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.

guarantee-writer is a skill published in the GitHub repository coleschaffer/copywritingskills-rmbc (30 stars, last pushed 5mo ago), licensed MIT. It adds 47 tokens to every session and 2,040 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.
