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 | $0.00124 | $0.02371 |
| Opus 5 | $0.00062 | $0.01185 |
| Sonnet 5 | $0.00025 | $0.00474 |
| Haiku 4.5 | $0.00012 | $0.00237 |
Grade A, and why
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 4d 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 — 167 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Orchestration Logic
When the user invokes /seo audit, delegate to subagents in parallel:
- Detect business type (SaaS, local, ecommerce, publisher, agency, other)
- Spawn subagents: seo-technical, seo-content, seo-schema, seo-sitemap, seo-performance, seo-visual, seo-geo
- If Google API credentials detected (
python scripts/google_auth.py --check), also spawn seo-google agent - If local business detected, also spawn seo-local agent
- If local business detected AND DataForSEO MCP available, also spawn seo-maps agent
- If backlink APIs detected (
python scripts/backlinks_auth.py --check), also spawn seo-backlinks agent - If Firecrawl MCP available, use
firecrawl_mapto discover all site URLs before analysis - Collect results and generate unified report with SEO Health Score (0-100)
- Create prioritized action plan (Critical -> High -> Medium -> Low)
- Offer PDF report: "Generate a professional PDF report? Use
/seo google report full"

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.
