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 | $0.00073 | $0.03615 |
| Opus 5 | $0.00036 | $0.01808 |
| Sonnet 5 | $0.00015 | $0.00723 |
| Haiku 4.5 | $0.00007 | $0.00362 |
Grade A, and why
cta-writing 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 — 594 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CTA Writing
Master the art of calls-to-action that convert. Direct CTAs, transitional CTAs, button copy, and microcopy that turns readers into customers.
When to Use This Skill
- Writing button text for landing pages and emails
- Creating CTAs for different stages of awareness
- Designing click-worthy microcopy
- A/B testing CTA variations
- Building email sequences with graduated CTAs
- Reducing friction at conversion points
Methodology Foundation
Source: Compiled from direct response advertising, CRO research, and modern SaaS best practices (Joanna Wiebe, Unbounce, CXL Institute studies).
Core Principle: A CTA isn't just a button—it's the bridge between desire and action. Great CTAs complete the thought: "I want to ______."
Why This Matters: Your page can do everything right, but if the CTA fails, the conversion fails. CTAs are the single most tested element in conversion optimization for a reason.
What Claude Does vs What You Decide
| Claude Does | You Decide |
|---|---|
| Structures production workflow | Final creative direction |
| Suggests technical approaches | Equipment and tool choices |
| Creates templates and checklists | Quality standards |
| Identifies best practices | Brand/voice decisions |
| Generates script outlines | Final script approval |
What This Skill Does
- Writes high-converting CTAs - Button text that gets clicked
- Matches CTA to funnel stage - Right ask at the right time
- Creates CTA variations - A/B test candidates
- Crafts transitional CTAs - Lower-commitment alternatives
- Writes supporting microcopy - Text around the CTA that reduces friction
How to Use
Generate CTAs
Write 10 CTAs for:
Product: [description]
Page goal: [signup, purchase, demo, etc.]
Audience awareness: [unaware, problem-aware, solution-aware, product-aware, most-aware]
Transitional CTAs
Create low-commitment CTAs for cold traffic:
Product: [description]
Ultimate goal: [final conversion]
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.

cta-writing is a skill published in the GitHub repository guia-matthieu/clawfu-skills (149 stars, last pushed 5mo ago), licensed MIT. It adds 73 tokens to every session and 3,615 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 2026-08-30.
