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 | $0.00035 | $0.01463 |
| Opus 5 | $0.00017 | $0.00732 |
| Sonnet 5 | $0.00007 | $0.00293 |
| Haiku 4.5 | $0.00003 | $0.00146 |
Grade A, and why
fb-ad-copy 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.

fb-ad-copy
Purpose
Generate direct response ad copy for Facebook/Meta campaigns using the RMBC framework. Each output delivers 3 variations (different hooks) for the chosen format — single image, carousel, or video script. Every variation includes primary text, headline, description, and CTA button recommendation with platform character limits enforced.
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, awareness level |
ad_format |
Yes | One of: single_image, carousel, video |
key_mechanism |
Yes | The product's unique mechanism (output from /mechanism-ideation) |
offer |
Yes | What the prospect gets — price, discount, bonus, guarantee |
tone |
No | One of: aggressive, conversational, professional. Default: conversational |
Execution Protocol
Step 1 — Load Framework Context
Read rmbc-context/SKILL.md to load RMBC framework definitions. Facebook ads compress the full RMBC arc into tight space — the hook carries Research (pain/desire), the body reveals Mechanism, proof stacks in mid-copy, and the CTA closes.
Step 2 — Map Awareness to Copy Length
| Awareness Level | Primary Text Approach |
|---|---|
| Unaware | Story/curiosity lead, longer primary text, educate before mechanism |
| Problem-aware | Lead with pain, mechanism as solution, proof to close |
| Solution-aware | Lead with mechanism differentiation, proof-heavy, direct CTA |
| Product-aware | Lead with offer, social proof, urgency |
| Most aware | Lead with new offer/angle, minimal education needed |
Step 3 — Generate 3 Variations
Each variation uses a different hook type (e.g., curiosity, fear, desire, social proof, contrarian). No two variations should use the same hook type.
Character Limits (enforced)
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.

fb-ad-copy is a skill published in the GitHub repository coleschaffer/copywritingskills-rmbc (30 stars, last pushed 5mo ago), licensed MIT. It adds 35 tokens to every session and 1,463 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.
