Orchestration Logic

Command Routing

1. 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)
   • 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)

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

How the 6 Pillars map to the FLOW framework (v1.7.0)

claude-blog adopts the FLOW evidence-led model (github.com/AgriciDaniel/flow, CC BY 4.0). The 6 Pillars stay as-is; they become the operational expression of FLOW's principles. Mapping:

Pillar	FLOW concept it implements	claude-blog adds beyond FLOW
Answer-First Formatting	"Extraction-readable" passages for AI Overviews and assistant citations	Concrete 40-60 word format spec
Real Sourced Data	The FLOW evidence triple: year anchor in prose + inline citation (publisher + title) + URL with retrieval date	Tier 1-3 source classification, blog-factcheck automation
Visual Media	(Outside FLOW scope; FLOW is asset-agnostic)	Full pipeline: Gemini image gen, SVG charts, stock libraries, YouTube embeds
FAQ Schema	Structured Q&A as an AI-citation surface signal	JSON-LD generation via blog-schema
Content Structure	"AI-readable document" with clear headings, direct answers, source labels	50-150 word chunk rule, proper H hierarchy enforcement
Freshness Signals	Year anchor in prose; source retrieval dates	dateModified schema, 30-day freshness threshold, blog-audit decay detection

The FLOW evidence triple is enforced AT DRAFTING time inside blog-write (not just at audit). For the full alignment doc (5-surface model, FLOW stages mapped to skills, what claude-blog adds), load references/flow-alignment.md. For the upstream FLOW framework itself, load skills/blog-flow/references/flow-framework.md or run /blog flow for prompt-driven workflows.

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.

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:

1. Parse -- Identify topic, detect platform, select template
2. Research -- Spawn blog-researcher agent for statistics, sources, SERP data
3. Outline -- Build section structure from template + research gaps
4. Write -- Spawn blog-writer agent with research packet and outline
5. Optimize -- Spawn blog-seo agent for on-page validation
6. Score -- Spawn blog-reviewer agent for 100-point quality audit
7. 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
