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 | $0.00055 | $0.02153 |
| Opus 5.5 | $0.00022 | $0.00861 |
| Sonnet 5.5 | $0.00011 | $0.00431 |
| Haiku 4.5 | $0.00006 | $0.00215 |
Grade A, and why
website-copywriting 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 2mo 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.

Website Copywriting
Overview
Use this skill to write or critique persuasive website copy that converts without becoming vague, manipulative, or trust-damaging.
Core thesis:
Good website copy meets the reader at their current awareness level, channels an existing desire/anxiety, makes one credible promise, proves it, resolves objections, and asks for the smallest honest next action.
This skill is grounded in old-school persuasion/copywriting principles from Cialdini, Hopkins, Ogilvy, and Schwartz, translated for modern websites.
Use When
- Writing website copy from scratch.
- Rewriting homepage hero, landing page, product page, pricing page, comparison page, FAQ, form, onboarding, upgrade, or CTA copy.
- Reviewing existing copy for conversion quality.
- Turning product positioning into page-level copy.
- Making copy more specific, credible, emotionally sharp, persuasive, or action-oriented.
- Diagnosing why copy feels generic, weak, over-clever, janky, or untrustworthy.
Do Not Do
- Do not invent customers, metrics, testimonials, awards, credentials, guarantees, deadlines, or scarcity.
- Do not use fake urgency, fake social proof, guilt CTAs, or hidden pressure.
- Do not hide risk, pricing, commitment, cancellation, or material caveats.
- Do not output generic sludge: “unlock your potential,” “supercharge your workflow,” “all-in-one platform,” etc.
- Do not treat cleverness as a substitute for clarity.
- When critiquing, do not rewrite before naming the strategic issue.
Minimum Inputs
Minimum viable copy needs:
- Product/service: what is being sold or explained?
- Audience: who is the copy for?
- Surface: homepage hero, landing page, pricing, CTA, etc.
- Conversion job: what should the visitor do next?
- Proof: what evidence is available, or what proof is missing?
If inputs are missing, ask one concise question when it materially changes the copy. If the user wants speed, proceed with labeled assumptions and flag proof gaps.

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.
