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 | $0.00119 | $0.01353 |
| Opus 5 | $0.00060 | $0.00677 |
| Sonnet 5 | $0.00024 | $0.00271 |
| Haiku 4.5 | $0.00012 | $0.00135 |
Grade A, and why
landing-page-generator 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 11d 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 — 100 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Landing Page Generator
Build landing pages that convert, as a single self-contained HTML file, then verify them with the bundled audit scripts.
Bundled Resources
| Resource | What It's For | When to Read/Run |
|---|---|---|
assets/template.html |
Production-ready page scaffold: 9 sections, 4 themes, SEO meta, schema, CWV optimizations baked in | Copy as the starting point for every new page |
references/copy-frameworks.md |
PAS/AIDA/BAB application, hero copy rules, CTA formulas, voice rules | Before writing any copy |
references/section-library.md |
Section-by-section patterns, variants, and rules | When adding/removing/adapting sections |
references/design-styles.md |
Theme selection, tokens, typography, imagery rules | When choosing a theme or applying brand colors |
references/optimization.md |
Manual checklists, CWV targets, A/B testing, troubleshooting, benchmarks | Before delivery; when diagnosing an underperforming page |
scripts/*.py |
Automated audits (see Verify step) | After every draft, before delivery |
Clarify First
Confirm these before generating. Ask only the 2-3 that most change the output; if the user says "just draft it," proceed and list assumptions at the top of the deliverable.
- Conversion goal & offer — the single action and what the visitor gets (one page, one goal, one CTA)
- Target audience & awareness level — selects the copy framework (see below)
- Key pain point & key benefit — drives the hero headline and Problem/Solution sections
- Traffic source — ads, email, or organic (sets message match)
- Brand constraints — existing colors/logo/screenshots, or free rein
Workflow
1. Choose framework and theme
Copy framework by audience awareness (details in references/copy-frameworks.md):
| Audience | Framework |
|---|---|
| Knows the problem | PAS |
| Needs education | AIDA |
| Wants transformation, knows solutions exist | BAB |

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-page-generator is a skill published in the GitHub repository buildfastwithai/gen-ai-experiments (763 stars, last pushed yesterday), licensed MIT. It adds 119 tokens to every session and 1,353 once invoked, about $0.0006 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.
