Installation

Clone the repository and open it as the agent workspace.

git clone https://github.com/seoskillsai/seo-skills-ai.git
cd seo-skills-ai
node packages/cli/index.mjs add cursor

@seoskillsai/cli is packaged for npm (package.json files includes skills/, scripts/, and AGENTS.md) but is not on the registry yet — there is no npm token in the local credential files. Do not run npx @seoskillsai/cli until a public 1.2.0 tarball exists.

Unix / macOS:

bash install.sh

Windows (PowerShell):

powershell -ExecutionPolicy Bypass -File .\install.ps1

Then point Claude Code, Cursor, Antigravity, Windsurf, Codex, or Cline at this folder. Skills load from skills/. Optional Playwright Chromium is installed by install.sh / install.ps1 for screenshots.

Claude Code CLI

/plugin marketplace add seoskillsai/seo-skills-ai
/plugin install seo-skills@seoskillsai-seo-skills
/seo setup
/seo doctor

Cline / Roo MCP

Copy config/cline_mcp_settings.json into your Cline MCP settings. Tools are not auto-approved; the host must confirm seo_audit and seo_drift because they fetch the URL you pass.

🏛️ What Makes SEO Skills Superior to Legacy Tools

Traditional SEO auditing tools (such as standalone browser extensions or single-agent plugins) rely on superficial regex scripts, obsolete Schema.org types, and generic prompt checklists. SEO Skills operates as an autonomous, multi-agent intelligence layer that executes deterministic code, inspects DOM rendering pipelines, and enforces holistic semantic authority:

🔍 Generative Engine Optimization (GEO) & AI Search Citability

Google AI Overviews, Perplexity Pro, and ChatGPT Search extract 130–170 word self-contained semantic answer passages directly from structured content. SEO Skills audits passage citability, question-based heading hierarchies, and entity attribution density to ensure your brand is cited as the primary authority.

🛠️ The 27 Modular SEO Skills Catalog

Every command in SEO Skills can be executed directly from your terminal CLI or invoked conversationally inside any AI agent workspace.

Core Audits & Architecture

• /seo audit <url>: Parallel full-site audit dispatching up to 15 specialist agents across technical, content, schema, GEO, and link vectors.
• /seo technical <url>: Comprehensive 9-category technical audit (Core Web Vitals INP/LCP/CLS, HTTP security headers, canonical loops, redirect chains, SPA hydration markers).
• /seo crawl <url> [max_pages]: Recursive multi-page site crawler mapping internal PageRank link graphs, crawl depth distribution ($\le 2$ clicks), and orphan pages.
• /seo drift <url>: SQLite on-page baseline snapshotting and 17-rule regression comparator to detect deployment code regressions.

Semantic Content & Topical Authority (Semantic SEO Standard)

• /seo content <url>: Holistic semantic content audit applying Entity-Attribute-Value (EAV) modeling and anti-thin educational prose validation ($800+$ words).
• /seo content-brief <topic>: Generates intent-grounded content briefs with macro/micro context, heading hierarchies, and directional link conduit targets.
• /seo cluster <seed>: SERP-overlap semantic keyword clusterer grouping search queries by top-10 URL overlap ($ \ge 4$ overlapping URLs = single pillar).
• /seo info-gain <url>: Google Patent US 11,562,019 B2 analyzer evaluating empirical data density, entity novelty, and SERP consensus deviation.
• /seo flow [stage]: 7-layer recursive multi-agent execution prompt flow guiding copywriters from entity research to final publication.

Structured Data & AI Search (GEO / AEO)

• /seo schema <url>: 2026 Google-compliant JSON-LD structured data validator and generator (enforces nested @graph with TechArticle, Product, BreadcrumbList).
• /seo llms-txt <url>: Dynamic /public/llms.txt and /public/llms-full.txt generator structuring site documentation for LLM ingestion.
• /seo robots-ai <url>: AI crawler permissions manager balancing citation discovery (GPTBot, ClaudeBot, Google-Extended) with scraper protection.

• /seo setup: Runtime provisioner bootstrapping isolated virtual environments and baseline databases.

Vendor APIs: first-party HTTP vs third-party MCP

This repo owns a small set of Python HTTP clients. Other vendors are official MCP servers you run with their keys; we do not bundle those servers.

First-party (our HTTP, credentials from env / ~/.config/seoskillsai/):

Third-party MCP (not our implementation): Ahrefs (@ahrefs/mcp), SE Ranking, Profound, Banana, Unlighthouse. See extensions/*/README.md. Example MCP snippets use ${ENV} placeholders — never commit empty "API_KEY": "" as if it were a secret.

🧠 Topical & Semantic SEO Principles

SEO Skills is founded upon the Topical Authority & Semantic SEO Standard, prioritizing topical source context and mathematical link equity over superficial keyword density:

1. Entity-Attribute-Value (EAV) Modeling:
   Every topic is constructed around a central entity ($E_0$), associated secondary entities ($E_1 \dots E_n$), defining attributes ($A$), and verified contextual values ($V$).
2. Directional PageRank Conduits:
   Link equity flows systematically upwards and horizontally: Outer Cluster Nodes $\rightarrow$ Category Silo Hub $\rightarrow$ Core Flagship Pillar.
3. 3x Anchor Text Diversity Rule:
   Exact-match target keyword anchor text must never appear more than 3 times across the entire website. Partial-match and semantic variations prevent over-optimization penalties.
4. Anti-Thin Educational Prose Architecture:
   Interactive tools, calculators, and widgets must be grounded with 800+ words of structured educational body prose to satisfy Google Quality Rater Guidelines (QRG §4.6.5).
5. Centerpiece Above-the-Fold Annotation:
   The primary interactive element or direct answer must render within the top 350px viewport (<600px mobile) to prevent centerpiece demotion penalties.

Security & Privacy

• No product telemetry: Audits and SQLite baselines stay on your machine. SEO Skills AI does not send analytics to seoskillsai.com.
• Network-target policy: User-supplied URLs go through scripts/url_safety.py (scheme, DNS fail-closed, private/metadata IP block, redirect re-check). Optional allowlist: SEOSKILLS_ALLOWED_HOSTS. Headless Chromium uses the same policy for navigation and blocks private-IP subresources.
• Repo scope: Generated files stay under SEOSKILLS_OUT_DIR (default: cwd). Remediation patches are review-only.
• MCP: Shipped Cline config does not autoApprove fetch tools.
• Host-agent hooks: hooks/hooks.json PreToolUse runs hook_validate_fetch.py / hook_validate_write.py on stdin JSON (no {file} shell interpolation).
• Playwright: navigation and private-IP subresources are aborted. Set SEOSKILLS_STRICT_BROWSER=1 to apply SEOSKILLS_ALLOWED_HOSTS to subresources too.
• Optional vendor APIs: PageSpeed, CrUX, RDAP, IndexNow, DataForSEO, Firecrawl, Bing Webmaster, and third-party MCP send the URL you asked to audit to those vendors when you run those commands.
• Credentials: Optional keys in ~/.config/seoskillsai/ with 0o600 permissions, gitignored.
