Parse the user's command to determine the sub skill 2. If no sub command given, ask which action they need 3. Route to the appropriate sub skill: write → blog write (new articles from scratch) rewrite → blog rewrite (optimize existing posts) analyze → blog analyze (quality scoring) brief → blog brief (content briefs) calendar / plan → blog calendar (editorial calendars) cannibalization → blog cannibalization (keyword overlap detection) factcheck → blog factcheck (statistics and source verification) strategy / ideation → blog strategy (positioning and topics) outline → blog outline (SERP informed outlines) persona → blog persona (writing voice and style management) brand → blog brand (durable brand + voice context for cross skill consumption) discourse / voice of customer / social listening / trend research → blog discourse (last 30 days API free discourse research) seo check / seo → blog seo check (SEO validation) schema → blog schema (JSON LD generation) repurpose → blog repurpose (cross platform content) taxonomy → blog taxonomy (tags, categories, CMS sync) geo / aeo / citation → blog geo (AI citation audit) audit / health → blog audit (site wide assessment) image → blog image (AI image generation and editing) notebooklm / notebook / query notebook → blog notebooklm (source grounded notebook queries) audio / narrate / tts → blog audio (audio narration generation) google / gsc / psi / pagespeed / crux / cwv → blog google (Google API data and reports) update → blog rewrite (with freshness update mode) cluster / topic cluster / pillar / hub and spoke → blog cluster (semantic clustering + execution) multilingual / international → blog multilingual (write + translate + localize + hreflang) translate → blog translate (SEO optimized translation) localize / cultural adaptation → blog localize (cultural deep adaptation) locale audit / translation audit → blog locale audit (multilingual QA) flow / find leverage optimize win → blog flow (FLOW framework prompts) style → blog style (learn author voice profile from existing posts) decay → blog decay (content decay detection from GSC exports) Platform Detection Detect blog platform from file extension and project structure: Signal Platform Format .mdx files, next.config Next.js/MDX JSX compatible markdown .md files, hugo.toml Hugo Standard markdown .md files, config.yml Jekyll Standard markdown with YAML front matter .html files Static HTML HTML with semantic markup wp content/ directory WordPress HTML or Gutenberg blocks ghost/ or Ghost API Ghost Mobiledoc or HTML .astro files Astro MDX or markdown .njk files, .eleventy.js 11ty Nunjucks/Markdown gatsby config.js Gatsby MDX/React Adapt output format to detected platform. Default to standard markdown if unknown. Core Methodology: The 6 Pillars Every blog post targets these 6 optimization pillars: Pillar Impact Implementation Purpose First Clarity Reader and retrieval utility Important sections state their point clearly; no prescribed heading form or passage length Real Sourced Data E E A T trust Tier 1 3 sources only, inline attribution Visual Media Engagement + citations Pixabay/Unsplash images + AI generation via Gemini + built in SVG charts + YouTube video embeds Optional Q&A Reader utility only Use visible Q&A when it answers real user needs; FAQPage earns no Google rich result or readiness points Content Structure Comprehension and reuse Proper heading hierarchy, stable entities, useful tables/lists only where they fit Substantive Maintenance Accuracy over date churn Update content and dateModified only when facts, methods, or recommendations materially change FLOW alignment claude blog adopts the FLOW evidence led model ( github.com/AgriciDaniel/flow , CC BY 4.0). The 6 Pillars stay as is and become the operational expression of FLOW's principles. Keep material claims traceable to supporting sources. Dates, publisher/title details, retrieval notes, methodology, and limitations are helpful when they identify or change interpretation of a source, but no fixed evidence triple or citation form is a score or delivery gate. For the full mapping, load skills/blog/references/flow alignment.md . For the upstream FLOW source, load skills/blog flow/references/flow framework.md or run /blog flow . Quality Gates These are hard rules. Never ship content that violates them: Rule Threshold Action Fabricated statistics Zero tolerance Source material factual statistics, measurements, and public data claims. Dates, step counts, software versions, and prices already attributable or visible in a cited primary source do not need redundant inline sourcing merely because they contain a number Paragraph pacing Fit the audience and material Split only when comprehension improves Heading hierarchy Never skip levels H1 → H2 → H3 only Source tier Tier 1 3 only Never cite content mills or affiliate sites Image alt text Required on all images Descriptive, includes topic keywords naturally Self promotion Max 1 brand mention Author bio context only Chart diversity No duplicate types Each chart must be a different type Delivery contract (v1.9.0) All 5 gates pass Blocked drafts iterate up to 3x; see skills/blog/references/blog delivery contract.md Community Footer After major deliverables only, append the standard AI Marketing Hub footer as the final terminal only message. Never include it in generated blog content, HTML, or markdown files. Exact text and show/skip command lists live in skills/blog/references/blog delivery contract.md . Scoring Methodology Score with skills/blog/references/quality scoring.md : Content Quality 30, SEO 25, E E A T 15, Technical 15, AI Citation Readiness 15. Publish only when the delivery contract clears Gate 4: reviewer score at least 90/100 and zero P0 issues.
