claude-blog is a Claude Code skill suite that writes, optimizes, audits, localizes, and refreshes blog content at scale. Every article is evaluated for Google-aligned usefulness and internal AI citation readiness heuristics. Version 2.1.1 was prepared on 2026-07-23.
The core promise is simple: the user is never the first reviewer. A 5-gate Blog Delivery Contract scores every draft against a 100-point rubric, blocks delivery below 90, verifies artifacts and links, and iterates up to 3 times before escalation.
This is the public, MIT-licensed distribution at
AgriciDaniel/claude-blog.
The publishing workflow is documented in
docs/PUBLISHING.md.

claude-blog is a full-lifecycle blog engine for strategy, briefs, outlines, writing, rewriting, analysis, schema, AI citation readiness, site audits, topic clusters, multilingual publishing, audio narration, and content decay detection.
Current v2.1.1 shape: 32 skill directories = 1 orchestrator + 31 sub-skills; 30 user-facing /blog commands (blog-chart is internal, not a command). It also includes 5 specialized agents, repository consistency and public-release validators, 22 core references, 12 templates, a 250+ test suite, and the bundled Claude Blog Brain at ./brain.
Every draft ships as an artifact folder with the markdown source, rendered HTML, PDF, real hero.<ext>, 3 viewport screenshots, review.md, and preflight-report.json. The renderer uses XSS-safe JSON-LD handling, dark-mode-aware CSS, and the same source for every output format.
Solo bloggers and creators can ship high-quality posts without spending hours on SEO, schema, source checks, and internal linking.
Marketing teams and agencies can run consistent multi-post workflows across brands, languages, authors, and platforms with /blog cluster, /blog multilingual, /blog persona, /blog brand, and /blog discourse.
Claude Code skill builders can study a Tier 4 Agent Skills reference architecture with orchestrator routing, sub-skill dispatch, agent handoffs, code-enforced delivery gates, installer hardening, and CI coherence checks.
Most user-installable Claude Code skill plugins should ship to ~/.claude/skills/<name>/ for skill content, ~/.claude/agents/<name>.md for agents, and ~/.claude/scripts/<helper>.py for Python helpers.
This answer is intentionally kept in the README because it demonstrates the GEO and SEO writing pattern claude-blog produces: answer-first summary, explicit paths, source-ready structure, and a compact FAQ-ready section that AI systems can quote without extra context.

## Where Should a Claude Code Skill Plugin Install Itself?
The short answer: most user-installable Claude Code skill plugins
should ship to `~/.claude/skills/<name>/` for skill content,
`~/.claude/agents/<name>.md` for agents, and
`~/.claude/scripts/<helper>.py` for any Python helpers.
### Key Takeaways
- `~/.claude/skills/` is the SKILL.md surface area.
- `~/.claude/agents/` holds agent markdown files.
- The full article includes sourced citations, FAQ, and schema JSON-LD.
The orchestrator in skills/blog/SKILL.md parses /blog input, detects the target platform, loads only the references it needs, routes to a sub-skill, and coordinates agents plus scripts through the delivery contract.
| Layer | Count | Where |
|---|---|---|
| Skill directories | 32 | skills/blog plus skills/blog-* |
| Orchestrator | 1 | skills/blog/SKILL.md |
| Sub-skills | 31 | skills/blog-*/SKILL.md |
User-facing /blog commands |
30 | skills/blog/SKILL.md routing table |
| Internal-only sub-skill | 1 | skills/blog-chart/SKILL.md |
| Specialized agents | 5 | agents/blog-*.md |
| Root scripts | 14 | scripts/*.py |
| References | 22 | skills/blog/references/*.md |
| Templates | 12 | skills/blog/templates/*.md |
| Tests | 252 | tests/ |
More architecture detail lives in docs/ARCHITECTURE.md.
Every /blog write and /blog rewrite result must pass the delivery contract before it is shown to the user.
| Gate | Enforces | Implementation |
|---|---|---|
| 1. Capability Discovery | Required tools, agents, env vars, and optional dependencies are known before writing | scripts/blog_preflight.py --gate 1 |
| 2. Format Completeness | .md, .html, .pdf, and a real hero image exist |
scripts/blog_render.py, scripts/generate_hero.py |
| 3. Visual Verification | Screenshots render at 375, 768, and 1280 widths, JSON-LD is valid, dark mode holds, SVGs do not overflow | patchright or playwright |
| 4. Content Review | blog-reviewer score is 90+ with zero P0 issues |
agents/blog-reviewer.md |
| 5. Asset and Link Integrity | Images resolve, og:image exists, links return 200, word count matches schema within 5% |
scripts/blog_preflight.py --gate 5 |
Hero image ladder: Banana MCP, direct Gemini API, premium stock APIs, then Openverse. First working source wins. Full spec: skills/blog/references/blog-delivery-contract.md.
The ecosystem is intentionally modular. Most commands are user-facing sub-skills. blog-chart is internal-only, and blog-image can be called both by the user and internally by write and rewrite workflows.

claude plugin validate .claude-blog is a structured pipeline. Direct LLM prompting is a one-shot. Hosted SaaS tools are closed-source. The tradeoffs are:
| Capability | claude-blog | Direct Claude or ChatGPT prompt | Copy.ai or Jasper | Build it yourself |
|---|---|---|---|---|
| Full article in one command with iteration loop | Yes | One-shot | Yes | No |
| Sourced statistics with verification | Yes | No | No | Manual |
| AI citation optimization (GEO / AEO) | Yes | No | No | Partial |
| Blocking content review with score 90+ | Yes | No | No | No |
| Multilingual plus hreflang in one command | Yes | Partial | Partial | No |
| Topic-cluster planning | Yes | No | Partial | No |
| Audio narration | Yes | No | No | No |
| Hero image generation ladder | Yes | No | Stock only | Partial |
| Persistent brand and voice context | Yes | Per-prompt | Limited | No |
| Open-source, MIT, no SaaS subscription | Yes | No | No | Yes |
claude-blog is not better at everything. Direct prompting is faster for a single throwaway draft. Hosted SaaS is easier for non-developers. DIY is more flexible for unique pipelines. claude-blog fits when you want production-grade content at scale without a SaaS subscription.
claude-blog is a Claude Code skill suite for writing, optimizing, and auditing blog content. It runs 32 skill directories through a 5-gate delivery contract so every article meets a 90/100 quality bar before it reaches you.
Direct prompting gives you one draft from one prompt. claude-blog gives you a structured pipeline: research with sourced statistics, outline approval, draft generation, multi-pass quality scoring, advisory editorial pattern review, fact verification, schema injection, and a blocking review that iterates up to 3 times before delivery.
Yes. AgriciDaniel/claude-blog
is MIT-licensed and available to anyone using Claude Code.
Next.js MDX, Astro, Hugo, Jekyll, WordPress, Ghost, 11ty, Gatsby, and static HTML. The orchestrator auto-detects the platform and adjusts frontmatter, image embedding, and schema injection.
The workflow is designed to block invented numbers. /blog factcheck fetches cited source URLs and scores each claim as exact match, paraphrase, or not found. blog-reviewer blocks publication when citations cannot be verified.
It is a pre-presentation pipeline for Capability Discovery, Format Completeness, Visual Verification, Content Review, and Asset and Link Integrity. The orchestrator iterates the writer up to 3 times on any gate failure before escalating to you. Full spec: skills/blog/references/blog-delivery-contract.md.
Yes. /blog multilingual <topic> --languages <codes> writes the post, translates it while preserving frontmatter and schema, runs cultural adaptation per locale, and emits hreflang tags plus a CMS-ready language map.
See How To Cite or CITATION.cff. GitHub also surfaces the citation through the public mirror.
The recommended flow downloads the installer as a file so you can inspect it before execution. v2.1.1 uses pinned refs, allowlisted recursive payload copies, manifest-backed uninstall, prose lint, version coherence checks, repository consistency checks, and installer regression tests.
