Security Scan

This is an instruction-only SEO audit checklist that is internally consistent with its stated purpose and does not request credentials, binaries, or install anything.

Purpose & Capability

The skill is a prose-driven SEO audit checklist and mapping to other SEO-focused skills. It declares no binaries, env vars, or installs — which is appropriate for a guidance-only audit skill.

Instruction Scope

SKILL.md stays on-topic: it lists technical, on-page, content, and off-page checks and tells the agent which related skills to use for specific checks. It does not instruct the agent to read arbitrary local files, query unrelated services, or exfiltrate data. Note: it expects the agent to call other skills (e.g., google-search-console, site-crawlability) to obtain data; those child skills may perform network calls or require credentials.

Install Mechanism

No install spec and no code files are present. Nothing will be written to disk or downloaded during install — lowest-risk model for a skill.

Credentials

This skill itself requires no environment variables or credentials. However, it explicitly delegates data collection to other SEO skills (like google-search-console) which may require tokens or API keys. Verify those dependent skills for any credential requests before enabling them.

Persistence & Privilege

always is false and the skill is user-invocable. It does not request persistent presence or modify other skills' configurations.

Assessment

This skill is a checklist and does not itself access your sites or secrets — it just tells the agent what to check and which other SEO skills to call. Before using it: (1) Understand that actual site data (crawl results, Search Console data, Core Web Vitals) will come from other skills or tools; review those skills for any credential or install requests. (2) If you don't want automated access to your Google Search Console or other accounts, do not grant credentials to the corresponding child skills. (3) Expect this skill to produce recommendations, not to perform scans by itself — you'll need crawler/GSC integrations to collect the evidence for the audit.

Strategies: SEO Audit

Guides end-to-end SEO audit: technical foundation, on-page, content, and off-page. Execute in order—technical blockers prevent indexing; on-page limits rankings; content and off-page build authority. Use when auditing an existing site or planning fixes.

When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.

Audit Order

Phase	Focus	Skills
1. Technical	Crawl, index, sitemap	robots-txt, xml-sitemap, canonical-tag, indexing, site-crawlability
2. On-Page	Metadata, structure, schema	title-tag, meta-description, page-metadata, schema-markup, internal-links, heading-structure
3. Content	Gaps, intent, optimization	keyword-research, content-strategy, content-optimization
4. Off-Page	Backlinks, authority	link-building, backlink-analysis

Principle: Fix foundation before optimizing pages. See seo-strategy for workflow and prioritization.
