Claude Blog is a free blog writing skill for Claude Code. Give it a topic and it researches current sources, writes the post, checks the SEO, has an independent reviewer score it and runs five delivery gates. You only see the post once it passes.

What you get:

• A finished post. Markdown, rendered HTML and PDF, a hero image with its license, and screenshots at phone, tablet and desktop widths plus dark mode.
• A reviewer that can say no. The blog-reviewer agent scores every post out of 100 and blocks anything under 90 or with a P0 issue.
• Sources you can check. Statistics come from tier 1 to 3 sources with dates, and /blog factcheck fetches every cited page to confirm the claim is there.
• SEO for Google and AI answers. Answer-first structure, Schema.org markup and Google’s latest guidance, so one post works for rankings and for citations in Google AI Overviews, ChatGPT, Perplexity and Gemini.
• Any language. /blog multilingual writes the post, translates and localizes it, and adds the hreflang tags.

Claude Blog is built from 32 skills and 5 specialist agents, with 30 /blog commands for everything around the post: strategy, topic clusters, audits, refreshes, images and audio.

Install

You need Claude Code and Python 3.11 or newer. Run these two commands inside Claude Code, then restart it:

/plugin marketplace add AgriciDaniel/claude-blog
/plugin install claude-blog@agricidaniel-blog

The analyzer’s two packages install with pip install -r requirements.txt. Rendering, screenshots and generated heroes use the optional presentation extra in pyproject.toml (Patchright, WeasyPrint, Markdown, Pillow, requests and google-genai); without a renderer, gate 3 blocks delivery instead of skipping it.

Your first post:

claude                                       # start Claude Code

/blog strategy "freelance CRM software"      # find the topics worth writing
/blog write "best CRM for freelancers"       # research, write, review, gates
/blog analyze posts/best-crm.md              # score any post you already have
/blog multilingual "best CRM for freelancers" --languages de,fr,es

The platform is detected for you (Next.js MDX, Astro, Hugo, Jekyll, WordPress, Ghost, 11ty, Gatsby or static HTML), and frontmatter, images and schema follow it.

How a post ships

1. It researches first. blog-researcher finds current statistics from tier 1 to 3 sources, with dates, plus image leads and the gaps other posts leave open.
2. It writes answer first. blog-writer drafts the post with every number sourced, and /blog renders it as Markdown, HTML and PDF with a hero image.
3. It has to pass. blog-reviewer scores the exact draft that ships, and five gates check it. When a gate blocks, the draft is fixed, rendered again and reviewed again, with 3 runs in all. If the third still fails you get the diagnostic, never a half-checked post.

Every rule lives in one file: blog-delivery-contract.md. Read the architecture for the rest.

What’s new

v2.3.2 makes Blog Studio work with the real engine, makes paid image calls opt-in in code and tightens the review gate. v2.3.1 added Blog Studio as an optional second plugin, and v2.3.0 brought the safe standalone installer, which backs up what it replaces and never deletes your own files.
