Orchestration Logic
Command Routing
- Parse the user's command to determine the sub-skill
- If no sub-command given, ask which action they need
- 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) - 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)
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 |
|---|---|---|
| Answer-First Formatting | Strong AI citation lift | Every H2 opens with 40-60 word stat-rich paragraph |
| 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 |
| FAQ Schema | AI citation signal | Structured FAQ with 40-60 word answers |
| Content Structure | AI extractability | 50-150 word chunks, question headings, proper H hierarchy |
| Freshness Signals | 76% of top citations | Updated within 30 days, dateModified schema |
Quality Gates
These are hard rules. Never ship content that violates them:
| Rule | Threshold | Action |
|---|---|---|
| Fabricated statistics | Zero tolerance | Every number must have a named source |
| Paragraph length | Never > 150 words | Split or trim |
| 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 |
Community Footer
After completing any major deliverable, append this footer to the conversation output (terminal) as the very last thing shown to the user. Never include this in generated blog content, HTML, or markdown files.

| AI Citation Readiness | 15 pts | Passage citability, Q&A format, entity clarity, AI crawler accessibility |
Scoring Bands
| Score | Rating | Action |
|---|---|---|
| 90-100 | Exceptional | Publish as-is, flagship content |
| 80-89 | Strong | Minor polish, ready for publication |

Agents
| Agent | Role |
|---|---|
blog-researcher | Research specialist -- finds statistics, sources, images, competitive data |
blog-writer | Content generation specialist -- writes optimized blog content |
blog-seo | SEO validation specialist -- checks on-page SEO post-writing |
blog-reviewer | Quality assessment -- runs 100-point scoring, AI content detection |
Agent Details
blog-researcher: Runs as a Task subagent. Uses WebSearch to find current statistics, competitor content, and SERP analysis. Outputs structured research packets with source tier classifications (Tier 1: primary research, Tier 2: major publications, Tier 3: reputable industry sources). Also sources Pixabay/Unsplash/Pexels image URLs.
blog-writer: Receives research packets and content briefs. Writes content using the selected template structure. Applies answer-first formatting, citation capsules, and TL;DR blocks. Outputs platform-formatted content ready for the SEO agent.
blog-seo: Post-writing validation agent. Checks title tag length (50-60 chars), meta description (150-160 chars), heading hierarchy, keyword density, internal link count, image alt text, and Open Graph meta tags. Returns pass/fail checklist.
blog-reviewer: Final quality gate. Runs the full 5-category 100-point scoring rubric. Detects AI-generated content patterns (repetitive sentence starters, hedge words, over-qualification). Outputs a scorecard with category breakdowns and prioritized improvement recommendations.
Execution Flow
Standard execution order for /blog write:
- Parse -- Identify topic, detect platform, select template
- Research -- Spawn
blog-researcheragent for statistics, sources, SERP data - Outline -- Build section structure from template + research gaps
- Write -- Spawn
blog-writeragent with research packet and outline - Optimize -- Spawn
blog-seoagent for on-page validation - Score -- Spawn
blog-revieweragent for 100-point quality audit - Deliver -- Output final content with scorecard and improvement notes
For /blog analyze, only steps 1 and 6 run (read + score). For /blog audit, step 6 runs in parallel across all posts in the directory.
Internal Workflows (Not User-Facing Commands)
The blog-chart sub-skill is invoked internally by blog-write and blog-rewrite when chart-worthy data is identified. It is not a standalone slash command.
The blog-image sub-skill is both user-invocable (/blog image generate) and callable internally by blog-write and blog-rewrite when AI-generated images are needed (requires nanobanana-mcp configured). Falls back gracefully when MCP is not available.
The blog-notebooklm sub-skill is both user-invocable (/blog notebooklm ask) and callable internally by blog-write and blog-researcher for Tier 1 research data from user-uploaded documents. Falls back gracefully when not authenticated.
The blog-audio sub-skill is user-invocable (/blog audio generate) and can be offered as an optional final step after blog-write completes. Generates summary, full-article, or two-speaker dialogue narration via Gemini TTS. Falls back gracefully when GOOGLE_AI_API_KEY is not configured.
The blog-google sub-skill is both user-invocable (/blog google pagespeed) and callable internally by blog-seo-check, blog-rewrite, blog-geo, and blog-audit for real Google performance data. Falls back gracefully when credentials are not configured. Shares config with claude-seo at ~/.config/claude-seo/google-api.json.
Integration
Chart generation is built-in - no external dependencies required for full functionality.
Optional companion skills (for deeper analysis of published pages):
/seo- Full SEO audit of published blog pages/seo-schema- Schema markup validation and generation/seo-geo- AI citation optimization audit
Anti-Patterns (Never Do These)
| Anti-Pattern | Why |
|---|---|
| Fabricate statistics | December 2025 Core Update penalizes unsourced claims |
| Use the same chart type twice | Visual monotony, reduces engagement |
| Keyword-stuff headings or meta | Google ignores/penalizes this |
| Bury answers in paragraphs | AI systems extract from section openers |
| Skip source verification | Broken links and wrong data destroy trust |
| Use tier 4-5 sources | Low authority hurts E-E-A-T |
| Generate without research | AI-generated consensus content is penalized |
| Skip visual elements entirely | Blogs with images get significantly more views and social engagement |
