A broad SEO analysis tool for websites and businesses. It reviews technical setup, content, structured data, images, sitemaps, and visibility in both traditional search and AI-generated search answers.

Use it for full-site or page audits covering crawling, indexing, Core Web Vitals, schema markup, content quality, images, sitemaps, and GEO.

It brings several common search-visibility checks into one analysis, helping reveal problems with a site or a single page.

Token cost

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	$0.00101	$0.04619
Opus 5.5	$0.00040	$0.01848

Security

Grade A, and why

seo scanned grade A with 2 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 20d ago.

The scan reads SKILL.md. This mod also ships 39 executable files (hooks/run-python-hook.js, hooks/validate-schema.py, scripts/agent_ux_check.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Reads agent configuration directorieslowAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

4. Chaves opcionais por variável de ambiente (bloco `env` do `~/.claude/settings.json` ou `.mcp.json`): `GOOGLE_APPLICATION_CREDENTIALS`/`GOOGLE_API_KEY` (seo-google), `BING_WEBMASTER_API_KEY`/`INDEXNOW_KEY` (seo-bing),

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Reads MCP configurationlowAgent snooping

mcp.json carries server URLs and auth tokens; reading it lets a mod discover and abuse other integrations.

How it starts

The opening of the file, as written. The whole thing — 301 lines — stays where its author put it; the contents beside it link to each section on GitHub.

SEO: Universal SEO Analysis Skill

Invocation: /seo $1 $2 where $1 is the command and $2 is the URL or argument.

Runtime: Run bundled Python tools through "${CLAUDE_PROJECT_DIR}/.claude/skills/seo/scripts/claude-seo" run <script.py>. That is the single canonical form used by every skill and agent. Claude Code expands ${CLAUDE_PROJECT_DIR}/.claude/skills/seo to the installed plugin directory, so the launcher is found without any PATH entry; the repository ships no top-level bin/ directory because hosted marketplaces reject one. Repository users run ./scripts/claude-seo; manual installers rewrite the canonical form to "$HOME/.claude/skills/seo/scripts/claude-seo". Never invoke bundled scripts with a bare Python interpreter.

Comprehensive SEO analysis across all industries (SaaS, local services, e-commerce, publishers, agencies). Orchestrates 24 sub-skills (21 core + 1 framework integration + 2 extension mirrors) and 15 sub-agents (ver "Subagents").

Instalação

Pré-requisitos e setup do runtime isolado (feito uma vez por máquina, por projeto):

Python 3.10+ disponível como python3 (ou aponte um interpretador com CLAUDE_SEO_PYTHON=/caminho/python3).
Rode "${CLAUDE_PROJECT_DIR}/.claude/skills/seo/scripts/claude-seo" setup (ou /seo setup). O launcher cria um venv isolado, instala requirements.txt (BeautifulSoup, Playwright, trafilatura, WeasyPrint, clientes Google etc.) e baixa o Chromium via Playwright para a renderização headless. Nada é instalado globalmente.
Confira com "${CLAUDE_PROJECT_DIR}/.claude/skills/seo/scripts/claude-seo" doctor --json (ou /seo doctor).
Chaves opcionais por variável de ambiente (bloco env do ~/.claude/settings.json ou .mcp.json): GOOGLE_APPLICATION_CREDENTIALS/GOOGLE_API_KEY (seo-google), BING_WEBMASTER_API_KEY/INDEXNOW_KEY (seo-bing), MOZ_API_KEY/KEYWORDSEVERYWHERE_API_KEY (seo-backlinks), DATAFORSEO_USERNAME/DATAFORSEO_PASSWORD (seo-dataforseo), GEMINI_API_KEY (seo-image-gen), API_KEY do MCP Ahrefs (seo-ahrefs).

What ships with it

60 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.

Changes

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.
