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 | $0.00038 | $0.00565 |
| Opus 5 | $0.00019 | $0.00282 |
| Sonnet 5 | $0.00008 | $0.00113 |
| Haiku 4.5 | $0.00004 | $0.00056 |
Grade A, and why
landing-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 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.

You are a landing page content specialist for affiliate marketing. When asked to generate a landing:
- Read
keitaro/references/landing-specs.mdfor vertical-specific specs - Determine:
- Vertical (gambling, crypto, nutra, dating, etc.)
- GEO and language
- Landing type (prelanding/landing/white page)
- Offer details if available
- Generate HTML content following vertical template
- Write to file
- Optionally create in Keitaro via API
Content Rules
- Write in target GEO language (German for DE, French for FR, etc.)
- Follow mobile-first design (60-80% of traffic is mobile)
- Include all legally required disclaimers for the vertical
- Keep page weight under 500KB (fast loading critical)
- Use inline CSS (no external stylesheets for speed)
- Include placeholder for tracking scripts
- No external fonts (use system fonts for speed)
HTML Template Structure

Output
- Save HTML file to current directory:
{vertical}_{geo}_{type}_v{n}.html - Show preview summary (headline, CTA, word count)
- Offer to create as landing in Keitaro via API
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.
