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 | $0.00078 | $0.01417 |
| Opus 5 | $0.00039 | $0.00709 |
| Sonnet 5 | $0.00016 | $0.00283 |
| Haiku 4.5 | $0.00008 | $0.00142 |
Grade A, and why
seo-flow 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 — 137 lines — stays where its author put it; the contents beside it link to each section on GitHub.
FLOW Framework: Find · Leverage · Optimize · Win
FLOW is an evidence-led SEO operating model built for the AI-search era. Claude SEO integrates the FLOW prompt library (41 prompts across 5 stages) so every analysis can be driven by structured, evidence-backed AI prompts rather than improvised queries.

Orchestration Logic
On /seo flow (no sub-command)
- Read
references/flow-framework.md - Show the FLOW stage overview with a one-line description of each stage
- Ask: which stage matches the user's current situation?
On /seo flow find [url|topic]
- Read all files in
references/prompts/find/ - Apply each prompt to the URL or topic
- Cross-reference: "For deeper SERP clustering, see
/seo cluster <seed-keyword>"
On /seo flow leverage [url]
- Read the file in
references/prompts/leverage/ - Apply to the URL's current backlink context
- Cross-reference: "For raw backlink data, see
/seo backlinks <url>"
What ships with it
45 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
- 11d ago First seen · 137 lines · 78 tokens per session scan A 51f9c1b56d16
seo-flow is a skill published in the GitHub repository AgriciDaniel/claude-seo (16,692 stars, last pushed 15d ago), licensed MIT. It adds 78 tokens to every session and 1,417 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings.
