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 | $0.00039 | $0.00882 |
| Opus 5.5 | $0.00016 | $0.00353 |
| Sonnet 5.5 | $0.00008 | $0.00176 |
| Haiku 4.5 | $0.00004 | $0.00088 |
Grade A, and why
international-seo 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.
How it starts
The opening of the file, as written. The whole thing — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.
International SEO
Audit the page for multi-language and regional targeting issues.
When to activate: Only relevant if the site serves multiple languages, regions, or has localised content. If a page is monolingual with no internationalisation signals, report ✅ PASS "No internationalisation issues (single-language site)".
1. Hreflang tags
Look for <link rel="alternate" hreflang="..."> in <head>:
| Check | Status |
|---|---|
| No hreflang tags on a multi-language site | ❌ FAIL "Add hreflang tags to indicate language/region variants" |
| Hreflang tags present | ✅ PASS — list all language-region codes found |
Hreflang validation rules
| Rule | Violation = |
|---|---|
| Self-referencing hreflang missing (page must include itself) | ❌ FAIL |
x-default fallback missing |
⚠️ WARN "Add hreflang=\"x-default\" for the default/fallback page" |
Invalid language code (must be ISO 639-1, e.g. en, fr, de) |
❌ FAIL |
Invalid region code (must be ISO 3166-1 alpha-2, e.g. en-US, fr-CA) |
⚠️ WARN |
| Hreflang URLs return 4xx or 5xx | ❌ FAIL "Hreflang points to broken URL" |
| Duplicate hreflang entries for same language-region | ⚠️ WARN |
2. HTML lang attribute
| Check | Status |
|---|---|
<html lang="..."> missing |
❌ FAIL |
lang value doesn't match hreflang self-reference |
⚠️ WARN "Mismatch between html lang and hreflang" |
| Properly set | ✅ PASS |
3. Content-Language header (meta)
<meta http-equiv="Content-Language" content="...">→ check if present- If present, verify it matches the
langattribute → ⚠️ WARN if mismatch
4. URL structure for internationalisation
Detect URL pattern used:
| Pattern | Example | Assessment |
|---|---|---|
| Subdirectory | /en/, /fr/, /de/ |
✅ Recommended |
| Subdomain | en.example.com |
✅ Acceptable |
| ccTLD | example.fr, example.de |
✅ Strong geo-targeting |
| URL parameter | ?lang=en |
⚠️ WARN "Not recommended — search engines may ignore parameters" |
5. Translated content checks
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.
