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 | $0.00084 | $0.01328 |
| Opus 5 | $0.00042 | $0.00664 |
| Sonnet 5 | $0.00017 | $0.00266 |
| Haiku 4.5 | $0.00008 | $0.00133 |
Grade A, and why
professional-copywriter 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.
How it starts
The opening of the file, as written. The whole thing — 140 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Professional Copywriting
Generate conversion-optimized website copy for SaaS and company pages. Primary constraint: never modify user-provided content unless explicitly requested.
Core Constraint: Preserve User Content
User-provided copy is sacred. Only generate or edit when:
- Content is missing/incomplete
- User explicitly requests changes
When in doubt, ask before modifying.
Writing Principles
Benefits Over Features
Translate every feature into user outcomes. Apply the "So what?" test.
Examples:
- ❌ "1,000-watt motor with stainless steel blades"
- ✅ "Blend frozen fruit in 10 seconds—no chunks, no hassle"
Structure for Scanning
- Descriptive headings that summarize content
- Short paragraphs (1-3 sentences)
- Bullet points for lists
- Inverted pyramid: critical info first
Clarity Over Cleverness
- Write conversationally
- Avoid jargon unless audience-specific
- Keep sentences short and direct
- Every word must serve a purpose
Address Pain Points
Ask questions that resonate with user problems: "Tired of [pain point]?" or "Ready to [desired outcome]?"
Voice & Specificity
- Have a stance — react to facts, don't just list them
- Vary rhythm — mix short punchy sentences with longer ones; uniform cadence reads as AI
- Be concrete — "Cut weekly reporting from 4hrs to 15min" beats "Streamline your workflow"
- Mirror customer language — use the words customers use in reviews, support tickets, and interviews; don't invent marketing vocabulary for them
AI Tells to Avoid
Strip these patterns. They make copy sound machine-generated and dilute trust.
- Significance puffery — "marks a pivotal moment", "stands as a testament", "in the evolving landscape", "deeply rooted"
- Promotional clichés — "nestled in the heart of", "groundbreaking", "vibrant", "robust", "seamless", "bespoke", "tailored", "meticulous", "unlock/unveil the secrets"
- Copula avoidance — "serves as / stands as / functions as" → just write "is"
- Fake-depth -ing tails — "...empowering teams, fostering collaboration, driving outcomes" (cut the trailing -ing clause)
- Negative parallelisms & forced triplets — "It's not just X, it's Y"; rule-of-three lists that pad with synonyms
- Em-dash & filler overuse — em dashes where commas/periods work; trim wordy phrases:
- "in order to" → "to"
- "at this point in time" → "now"
- "the ability to" → "can"
- Vague attributions — "industry leaders", "experts agree", "studies show" without a specific source
- Stale connectors — "not only", "designed to enhance", "when it comes to", "in the realm of", "amongst"
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.

professional-copywriter is a skill published in the GitHub repository teamniteo/hakuto (5 stars, last pushed 7d ago), licensed MIT. It adds 84 tokens to every session and 1,328 once invoked, about $0.0004 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 2026-08-31.
