What it does

SEO is an agent skill from AgriciDaniel/seo-os. Comprehensive SEO analysis for any website or business type. Full site audits, single-page analysis, technical SEO (crawlability, indexability, Core Web Vitals with INP), schema markup, content quality (E-E-A-T), image optimization, sitemap analysis, and GEO for AI Overviews/ChatGPT/Perplexity. Industry detection for SaaS, e-commerce, local, publishers, agencies. Triggers on: SEO, audit, schema, Core Web Vitals, sitemap, E-E-A-T, AI Overviews, GEO, technical SEO, content quality, page speed, structured data.

Its SKILL.md is about 3.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 14 other files, including reference files (for example `references/backlink-quality.md`, `references/cwv-thresholds.md` and `references/eeat-framework.md`).

It sits in Marketing & SEO, covering Technical SEO, SEO audit and Web performance. It works with OpenAI and Perplexity. The repository describes itself as: SEO Office is a local-first SEO agency operating system. claw3d UI + claude-seo specialists + marketing-brain. Distributed as a private repo to a non-technical community. The licence is MIT.

When your agent uses it

  • Core Web Vitals
  • Content quality
  • Structured data

Example prompts

  • “/seo”

Requirements

  • Python 3

Workflow steps

12 steps, taken from the first numbered list in SKILL.md.

  1. Detect business type (SaaS, local, ecommerce, publisher, agency, other)
  2. Spawn subagents: seo-technical, seo-content, seo-schema, seo-sitemap, seo-performance, seo-visual, seo-geo
  3. If Google API credentials detected (python scripts/google_auth.py --check), also spawn seo-google agent
  4. If local business detected, also spawn seo-local agent
  5. If local business detected AND DataForSEO MCP available, also spawn seo-maps agent
  6. If backlink APIs detected (python scripts/backlinks_auth.py --check), also spawn seo-backlinks agent
  7. If Firecrawl MCP available, use firecrawl_map to discover all site URLs before analysis
  8. If content strategy signals detected (blog, pillar pages, topic clusters), also spawn seo-cluster agent
  9. If e-commerce detected, also spawn seo-ecommerce agent
  10. If drift baseline exists for this URL (python scripts/drift_history.py ), also spawn seo-drift agent
  11. Always include seo-sxo in full audits (search experience applies to all sites)
  12. Collect results and generate unified report with SEO Health Score (0-100)

What it can do on your machine

Read from SKILL.md and the folder at commit f2ba248. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • python

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • skool.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

SEO loads about 3.5k tokens when it runs, and up to ~22k if it reads all its reference files. Until then it costs about 129 tokens; SKILL.md has 1,563 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~129
When it runs · the whole SKILL.md, loaded when a task matches
~3.5k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~22k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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

Scripts: Located at the plugin root scripts/ directory.

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 18 sub-agents. A separate optional Firecrawl extension is also installable (see "Optional Extensions" below).

Orchestration Logic

When the user invokes /seo audit, delegate to subagents in parallel:

  1. Detect business type (SaaS, local, ecommerce, publisher, agency, other)
  2. Spawn subagents: seo-technical, seo-content, seo-schema, seo-sitemap, seo-performance, seo-visual, seo-geo
  3. If Google API credentials detected (python scripts/google_auth.py --check), also spawn seo-google agent
  4. If local business detected, also spawn seo-local agent
  5. If local business detected AND DataForSEO MCP available, also spawn seo-maps agent
  6. If backlink APIs detected (python scripts/backlinks_auth.py --check), also spawn seo-backlinks agent
  7. If Firecrawl MCP available, use firecrawl_map to discover all site URLs before analysis
  8. If content strategy signals detected (blog, pillar pages, topic clusters), also spawn seo-cluster agent
  9. If e-commerce detected, also spawn seo-ecommerce agent
  10. If drift baseline exists for this URL (python scripts/drift_history.py <url>), also spawn seo-drift agent
  11. Always include seo-sxo in full audits (search experience applies to all sites)
  12. Collect results and generate unified report with SEO Health Score (0-100)
  13. Create prioritized action plan (Critical -> High -> Medium -> Low)
  14. Offer PDF report: "Generate a professional PDF report? Use /seo google report full"

For individual commands, load the relevant sub-skill directly. After any analysis command completes, offer to generate a PDF report via scripts/google_report.py.

Industry Detection

Detect business type from homepage signals:

  • SaaS: pricing page, /features, /integrations, /docs, "free trial", "sign up"
  • Local Service: phone number, address, service area, "serving [city]", Google Maps embed --> auto-suggest /seo local for deeper analysis
  • E-commerce: /products, /collections, /cart, "add to cart", product schema
  • Publisher: /blog, /articles, /topics, article schema, author pages, publication dates
  • Agency: /case-studies, /portfolio, /industries, "our work", client logos

Quality Gates

Read references/quality-gates.md for thin content thresholds per page type. Hard rules:

  • WARNING at 30+ location pages (enforce 60%+ unique content)
  • HARD STOP at 50+ location pages (require user justification)
  • Never recommend HowTo schema (deprecated Sept 2023)
  • FAQ schema for Google rich results: only government and healthcare sites (Aug 2023 restriction); existing FAQPage on commercial sites -> flag Info priority (not Critical), noting AI/LLM citation benefit; adding new FAQPage -> not recommended for Google benefit
  • All Core Web Vitals references use INP, never FID

To copy it by hand, put the folder in .cursor/skills/seo, .gemini/skills/seo, .github/skills/seo and .opencode/skills/seo in your project.

What does SEO need to run?

Going by SKILL.md and its folder, SEO needs the command-line tools its instructions call (python). Our summary lists: Python 3.

Does SEO access the network?

SKILL.md names 1 domain. In commands or code: skool.com; the agent is likely to contact it when it follows the instructions. This is read from the text; nothing was executed.

Is SEO safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does SEO use?

SEO is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does SEO use?

About 3.5k tokens (SKILL.md is roughly 14k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 18k tokens, read only when the agent opens those files.

What are the alternatives to SEO?

Skills that share tags, products or a category with SEO: SEO (AgriciDaniel/codex-seo, 797 stars), SEO (Nexus-JPF/note-companion, 870 stars), GEO-First SEO Audit Tool (zubair-trabzada/geo-seo-claude, 11k stars) and SEO Geo (EliasOulkadi/shokunin, 114 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
