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.

What it costs to keep this loaded
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 | $0.00108 | $0.01456 |
| Opus 5 | $0.00054 | $0.00728 |
| Sonnet 5 | $0.00022 | $0.00291 |
| Haiku 4.5 | $0.00011 | $0.00146 |
Grade A, and why
landing-pages 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 9d 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 — 168 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Landing Pages
Overview
A landing page has one job: convert visitors into leads. Every element that doesn't serve that goal is distraction. The best landing pages make a single promise, prove it quickly, and make the next step frictionless.
This skill audits existing pages against conversion best practices and produces prioritized fix lists with before/after recommendations.
When to Use
- "Audit our landing page"
- "Why isn't our page converting?"
- "Improve our signup flow"
- "Optimize our demo request page"
- "What should we A/B test?"
- "Redesign our hero section"
Authoritative Foundations
Robert Cialdini's seven principles of persuasion (reciprocity, commitment, social proof, authority, liking, scarcity, unity) form the psychological foundation of effective landing pages.
Joanna Wiebe's conversion copywriting framework: start with the prospect's problem, not your product. Write copy that answers the question "what's in it for me?" in the first three seconds.
Step-by-Step Process
Phase 1: Audit Current Page
Score the page against the CRO checklist:
Above the fold (most critical):
- Hero headline states value in <10 words
- Subheadline explains who it's for and what they get
- Primary CTA is visible, specific, and action-oriented
- Social proof visible (logos, testimonials, metrics)
- No navigation elements that compete with the CTA
Body:
- Benefits, not features. Each section answers "so what?"
- Proof points: customer logos, case study pulls, metrics
- Objections pre-handled (security, pricing, integration concerns)
- Mobile-optimized: text readable, buttons tappable, no horizontal scroll
CTA:
- Single primary CTA per page
- CTA copy is specific ("Get your free audit" > "Submit")
- Minimized form fields (fewer fields = higher conversion)
- Trust signals near CTA (no credit card required, SOC 2, etc.)
Phase 2: Conversion Architecture
Structure the page for scanning, not reading:
What ships with it
5 files 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.

landing-pages is a skill published in the GitHub repository LeadMagic/gtm-skills (50 stars, last pushed 5d ago), licensed MIT. It adds 108 tokens to every session and 1,456 once invoked, about $0.0005 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 2026-09-03.
