Claude SEO is an open-source Claude Code plugin that runs specialized agents and skills to audit websites across technical SEO, content quality, structured data, AI-search optimization, local and e-commerce SEO, and international SEO. SEO practitioners use it to produce prioritized recommendations based on primary-source guidance, with optional extensions for external data and crawling.
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 | $0.00116 | $0.03787 |
| Opus 5 | $0.00058 | $0.01894 |
| Sonnet 5 | $0.00023 | $0.00757 |
| Haiku 4.5 | $0.00012 | $0.00379 |
Grade A, and why
seo-google 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 10d 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 — 364 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Google SEO APIs
Direct access to Google's own SEO data. Bridges the gap between crawl-based analysis (existing claude-seo skills) and Google's real-time field data: actual Chrome user metrics, real indexation status, search performance, and organic traffic.
All APIs are free. Setup requires a Google Cloud project with API key and/or
service account -- run /seo google setup for step-by-step instructions.
Prerequisites
Before executing any command, check credentials:
claude-seo run google_auth.py --check --json
Config file: ~/.config/claude-seo/google-api.json
{
"service_account_path": "/path/to/service_account.json",
"api_key": "<GOOGLE_API_KEY>",
"default_property": "sc-domain:example.com",
"ga4_property_id": "properties/123456789"
}
If missing, read references/auth-setup.md and walk the user through setup.
Credential Tiers
| Tier | Detection | Available Commands |
|---|---|---|
| 0 (API Key) | api_key present |
pagespeed, crux, crux-history, youtube, nlp |
| 1 (OAuth/SA) | + OAuth token or service account | Tier 0 + gsc, inspect, sitemaps, index |
| 2 (Full) | + ga4_property_id configured |
Tier 1 + ga4, ga4-pages |
| 3 (Ads) | + ads_developer_token + ads_customer_id |
Tier 2 + keywords, volume |
Always communicate the detected tier before running commands.

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.
