abogado-del-diablo
ES — Critica a fondo una idea, plan, pitch o proyecto entero sin validar ni adular: asume que va a fracasar y lo demuestra por ocho ángulos (premisas, mercado, competencia, viabilidad, números, ejecución, pre-mortem y punto ciego), investiga fracasos reales cuando hay herramientas, y entrega un veredicto franco con la lista priorizada de qué arreglar. Activar con /abogado-del-diablo, "hazme pedazos esto", "critica mi idea sin filtros", "dime por qué va a fallar", "destruye este plan", "segunda opinión brutal", "pre-mortem". EN — Harshly critiques an idea, plan, pitch, or whole project without validating; assumes it will fail and proves it across eight angles, then returns a blunt verdict with a prioritized fix list. Trigger on "devil's advocate", "red team this", "tear this apart", "why will this fail", "brutal second opinion", "pre-mortem".
fix
Opt-in fixer (the /claude-seo-ai:fix command). Applies the safe, deterministic SEO/AI-search fixes from an audit to the user's code — meta viewport/charset/lang, JSON-LD, robots.txt AI directives, hreflang, sitemaps, OG/Twitter cards, image dimensions, canonical, llms.txt. Dry-run preview by default; writes only after explicit per-change confirmation. Runs only when the user invokes it — never auto-triggered.
seo-ai-crawlers
Audit AI crawler access and citability for a page — confirm retrieval/citation bots (OAI-SearchBot, Claude-SearchBot, PerplexityBot) are allowed and the Googlebot vs Google-Extended split is correct, classify training vs search/retrieval vs user-fetch user-agents, check the page is server-rendered enough for non-JS AI crawlers, validate llms.txt / llms-full.txt (also covers M21), and generate a choice-gated robots.txt preset. Module M14. Feeds the AI Visibility score.
seo-core-web-vitals
Audit Core Web Vitals & page performance — measure LCP, INP, and CLS against p75 field thresholds, diagnose render-blocking resources, unoptimized images, and layout-shift sources, and produce prioritized, advisory-only remediation guidance. Module M15. Feeds the Search SEO score (heavily) and the AI Visibility score (minimally).
seo-crawl-render
Fetch a page (or local files) and build the shared PageSnapshot every audit module reads — raw HTML, rendered DOM when a render MCP is available, response headers, status/redirect chain, and site artifacts (robots.txt, sitemaps, llms.txt). Decides whether JavaScript rendering is needed and records the data tier.
seo-crawlability
Audit and generate robots.txt and general crawl access for a page — verify robots.txt reachability and syntax, detect Disallow rules that block CSS/JS or important content, sanity-check crawl-delay, confirm a Sitemap directive, and assert overall crawl access for Googlebot/Bingbot. Module M1. Feeds the Search SEO score.
seo-ecommerce
Conditionally audit and generate e-commerce structured data for product pages — validate Product/Offer (price, priceCurrency, availability), AggregateRating/Review, faceted-navigation canonicalization, and variant/ProductGroup handling, cross-checking page-to-schema-to-Merchant-feed consistency, and produce ready-to-inject Product JSON-LD. Module M18. Feeds both the Search SEO and AI Visibility scores.
seo-eeat
Audit and strengthen E-E-A-T and trust signals on a page — verify author identity/credentials (Person schema, byline, author page, sameAs), Organization about/contact/policies, visible experience/expertise markers, and transparency (sourcing, disclosures), and generate Person/Organization trust JSON-LD. Module M16. Feeds both the Search SEO and AI Visibility scores.
seo-entity-linking
Audit and generate entity & knowledge-graph linkage for a page — verify sameAs identity links (Wikidata/Wikipedia/LinkedIn/Crunchbase/official profiles) on Organization/Person, check NAP/entity consistency for local, confirm a defined primary entity, and measure entity density, then propose ready-to-inject sameAs/about/mentions references. Module M6. Feeds the AI Visibility score.
seo-freshness
Audit and repair freshness & temporal signals on a page — reconcile visible publish/update dates with schema datePublished/dateModified, flag staleness against topic volatility, and inject honest dateModified. Module M13. Feeds both the Search SEO and AI Visibility scores.
seo-geo-answerblocks
Audit and generate answer-extractable content — verify each question heading is followed by a ~40-60 word direct answer, passages are self-contained (~134-167 words, no unresolved anaphora), and lists/tables/definitions/TL;DR blocks exist; draft answer-block and summary rewrites for the user to accept. Module M11. Feeds the AI Visibility score.
seo-geo-factdensity
Audit fact density and sourcing on a page — measure statistic/number density per passage, detect proprietary/original data, count outbound citations to authoritative sources, and flag claims made without a supporting stat or source. Module M12. Feeds the AI Visibility score. Advisory-only; never fabricates statistics or sources.
seo-headings-structure
Audit and propose fixes for a page's heading hierarchy and semantic outline — verify exactly one H1, logical H2-H6 nesting with no skipped levels, descriptive heading text, and HTML5 landmarks (article/section/nav/main/footer) — so the document outline is extractable. Module M7c. Feeds the Search SEO score (clean headings also support AI answer-block extraction, which is scored separately under M11).
seo-images-media
Audit and fix image & media accessibility for a page — detect missing/empty/duplicated/keyword-stuffed alt text, check alt quality and length, missing width/height (CLS), legacy formats, and absent VideoObject schema; generate contextual alt and dimensions. Module M9. Feeds both the Search SEO and AI Visibility scores.
seo-indexability
Audit a page's indexability and site health — canonical presence/validity (self vs cross-domain vs chain, canonical to redirect/404, the lethal canonical+noindex pair), robots meta and X-Robots-Tag noindex/nofollow, duplicate clusters, pagination signals, plus redirect chains/loops, 4xx/5xx and soft-404 internal links, mixed content, HTTP-to-HTTPS enforcement, orphan pages and click-depth — and generate self-referential canonical / noindex-removal fixes. Module M2 (covers M3 site health). Feeds the Search SEO score.
seo-internal-linking
Audit and improve a site's internal-linking topology and semantic HTML — map pillar/cluster structure, count and grade contextual in-body links and anchor text, surface orphan pages and nav-heavy templates, and propose specific source→target link insertions. Module M10. Feeds the Search SEO score.
seo-international
Audit and generate hreflang annotations for multilingual sites — check reciprocity, BCP-47 validity, self-reference, x-default, hreflang/canonical conflicts, and <html lang> agreement, and emit reciprocal hreflang link sets. Module M20 (conditional). Feeds the Search SEO score.
seo-local
Audit and generate Local SEO signals for local-business pages — verify LocalBusiness JSON-LD, NAP consistency, geo coordinates, openingHoursSpecification, and service-area, advise on Google Business Profile alignment, and produce ready-to-inject LocalBusiness JSON-LD. Module M19 (conditional). Feeds both the Search SEO and AI Visibility scores.
seo-meta-onpage
Audit and generate the document head — title (50-60 chars), meta description (150-160 chars), viewport, charset, <html lang>, and robots-meta sanity — flagging missing/duplicate/over-long values and producing length-bounded, keyword-aware replacements. Module M7. Feeds the Search SEO score.
seo-mobile
Audit mobile-friendliness of a page from the PageSnapshot — verify the viewport meta, no horizontal-scroll/fixed-width layouts, adequate tap targets, legible base font, and mobile/desktop content parity — and generate the viewport meta when missing. Module M7b. Feeds the Search SEO score.
seo-orchestrator
Orchestrates a full SEO + AI-search audit — detects the site vertical, builds a shared PageSnapshot, dispatches read-only specialist subagents in parallel, merges their findings, computes the two scores, and renders the report. Invoked by the `audit` command (the /claude-seo-ai:audit skill); not usually called directly.
seo-rendering
Audit a page's rendering strategy and JavaScript dependency — diff raw HTML against the rendered DOM to measure how much primary content, links, headings, and JSON-LD exist only after JS executes, classify CSR-only / SSR / SSG / ISR, and emit framework-specific guidance. Module M4. Feeds both the Search SEO and AI Visibility scores.
seo-schema-jsonld
Audit and generate structured data (JSON-LD) for a page — detect, validate, and complete Tier-1 schema.org types (Article, Organization, Person, Product/Offer, BreadcrumbList, LocalBusiness, Review, VideoObject, Event), flag microdata/RDFa and deprecated-for-rich-results types (FAQPage/HowTo), and produce ready-to-inject JSON-LD blocks. Module M5. Feeds both the Search SEO and AI Visibility scores.
seo-sitemaps
Audit and generate sitemaps and discovery files — validate XML sitemap presence/size/extensions/lastmod, check robots.txt referencing and sitemap-to-canonical consistency, reconcile orphans against the link graph, and produce repaired sitemap entries plus a robots.txt Sitemap line. Module M17. Feeds the Search SEO score.
seo-social-cards
Audit and generate Open Graph and Twitter/X social-card tags for a page — check og:title/description/url/type, og:image presence/size/reachability, and twitter:card/title/description/image, then inject complete card tags inferred from the page. Module M8. Feeds the Search SEO score.
audit
Audit a website or web codebase for SEO and AI-search (GEO/AEO) — produces two independent 0-100 scores (Search SEO + AI Visibility) plus a prioritized, evidence-backed report. Read-only; never writes files. Use when the user asks to audit, analyze, check, or score a site's SEO, structured data/schema, meta tags, Core Web Vitals, robots.txt, sitemaps, or llms.txt, or how it ranks in Google and is cited by AI engines (ChatGPT, Perplexity, Google AI Overviews, Gemini, Claude).
geo
Analyze and score only a page's AI-search visibility (GEO/AEO) — answer extractability, fact density, AI-crawler access, entity linking, and llms.txt — and report an AI Visibility score with a citability breakdown. Read-only. Use for "will AI engines cite this?", GEO/AEO, or ChatGPT/Perplexity/Google AI Overviews/Gemini optimization.
score
Recompute and display the two scores (Search SEO + AI Visibility) from the most recent audit's findings, without re-crawling. Use to re-show or refresh the scores after an audit, or to score a saved findings JSON file.
seo-score
Compute the two never-blended 0-100 scores (Search SEO and AI Visibility / GEO-AEO) from a set of findings, with severity-weighted category values, dynamic re-normalization of conditional modules, severity gating, and letter bands. Used by seo-orchestrator and the `score` command.
seo-vertical-detect
Classify a website as ecommerce, local-business, blog-publisher, saas, docs, or generic (multiple may apply), and report detected locales. Used by seo-orchestrator to decide which conditional modules to run and how to reweight the scores.
