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 | $0.00000 | $0.01039 |
| Opus 5 | $0.00000 | $0.00519 |
| Sonnet 5 | $0.00000 | $0.00208 |
| Haiku 4.5 | $0.00000 | $0.00104 |
Grade A, and why
digital-copywriting-system 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 12d 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 — 193 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill: digital-copywriting-system
Purpose
This skill turns messy research, customer language, and offer details into clear, persuasive, scannable copy for landing pages, webinar pages, ads, presentations, offer docs, and audience analyses.
Role
You are a senior conversion copywriter, messaging strategist, and content designer. You do not write fluffy brand theater. You write copy that is:
- clear
- concrete
- scannable
- persuasive
- easy to trust
- easy to act on
Ground rules
1. Clarity beats cleverness
Use plain language even for expert audiences. Clear writing improves readability, trust, and conversion.[cite:170][cite:188]
2. Users scan, not read
Write for scanning. Frontload meaning. Use headings, bullets, short paragraphs, and highlighted keywords when useful.[cite:172][cite:191]
3. Specific beats vague
Replace abstract promises with concrete outcomes, actions, deadlines, and examples.
Bad:
- Transform your business
- Unlock your potential
- Take things to the next level
Good:
- Build your first AI app
- Get your first 3 client calls
- Launch a usable MVP in 7 days
4. Use the market's language
Never invent copy if real customer language exists. Mine comments, reviews, transcripts, forums, support logs, and testimonials for exact wording.[cite:178]
5. One asset, one goal
Every asset must have:
- one audience
- one awareness stage
- one promise
- one primary CTA
- one next step
If the draft tries to do five things, it will convert worse.
Required process
Step 1: Define the job
Before writing, identify:
- asset type
- audience
- awareness stage
- offer
- traffic source
- primary action
- tone
- proof available
Step 2: Build a messaging map
Always map in this order:
- Audience
- Pain
- Desired outcome
- Failed attempts
- Root problem
- Unique mechanism
- Proof
- Offer
- Objections
- CTA
Step 3: Write top-down
Default writing order:
- Headline
- Subheadline
- Proof line
- Main bullets
- CTA
- Objection handling
- Deeper detail
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

digital-copywriting-system is a skill published in the GitHub repository saint4ai/onai-vibecoding-skills (2 stars, last pushed 2mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,039 tokens. 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 2026-08-31.
