Claude Blog Skill

The Decision

Claude Blog Skill is a full-stack content factory with 30 specialized sub-skills. It transforms a single keyword into a complete, SEO-optimized blog post with a hero image and distribution assets for LinkedIn, Twitter, and newsletter.

It replaces the entire stack: Grammarly (editing), Clearscope (SEO), Midjourney (images), and Buffer (distribution snippets). All wired together in one Agent pipeline.

Our testing rates it 9.3/10. It is the most comprehensive blog production skill available open-source (1164 stars).

Who It’s For

• Bloggers looking to scale content output without hiring writers
• SEO teams needing consistent on-page optimization across many articles
• Content agencies automating client deliverables
• SaaS founders building thought leadership at scale

Who Should Skip

• Personal diary bloggers (no SEO needed)
• Writers who enjoy crafting every sentence manually
• Anyone without a clear SEO strategy (this amplifies strategy; it doesn’t replace it)

Why This Skill Matters

Blog content creation is fragmented: you research keywords, write an article, edit it, optimize for SEO, find/create a hero image, then write social posts to promote it. That’s 5+ separate tools and hours of work per article. Claude Blog Skill combines all these steps into a single pipeline that runs in your terminal. Input a keyword, get a ready-to-publish article package.

Real-World Case Study: Automating Blog Posts from Project Folders in 30 Seconds

The Challenge

You’re a solo developer who maintains a personal blog about your projects. Every time you finish a new project, you want to write a blog post about it. But the process is tedious:

• Find screenshots in the project folder
• Copy images to the blog’s assets directory
• Create a new MDX file with correct frontmatter
• Write the post content
• Remember the right category and tag format
• Commit and preview

This takes 30+ minutes per post. Goal: reduce it to a single command that generates the entire post.

The Prompt Chain (Exact Steps)

1. Create a Custom Blog Skill

   Create a Claude Code Skill file at ~/.claude/skills/blog.md with the following structure:
   
   # Blog Post Skill
   Create a new blog post for jovweb.dev about a project or topic.
   
   ## Usage
   /blog [project-folder-or-topic]
   
   ## Arguments
   - $ARGUMENTS: path to a project folder or a topic to write about
   
   ## Instructions
   1. Parse $ARGUMENTS to get the project folder or topic
   2. If a folder path is provided, explore it to understand:
      - What the project does (check README, package.json, main source files)
      - Key features and technologies used
      - Any screenshots or images in the repo
   3. Find images in /public, /assets, /images, /screenshots
   4. Copy the best image to /path/to/blog/public/assets/blog/
   5. Create an outline based on: problem solved, how it works, key features
   6. Write the blog post content
   7. Create the MDX file with frontmatter (title, description, date, category, tags)

   Agent output: A reusable /blog command that automates the entire blog post creation process.

2. Create a Rewrite Skill for Style Consistency

   Create a rewrite skill at ~/.claude/skills/rewrite.md:
   
   # Rewrite Skill
   Rewrite text using my personal style guide.
   
   ## Style Guide
   - start with lowercase
   - use "I" not "I"
   - no ending punctuation
   - short, direct sentences
   - stream of consciousness flow

   Agent output: A /rewrite command that converts AI-generated drafts into your personal writing style.

3. Run the Blog Command

   /blog ~/Sites/hyperscalper

   Agent output: Claude Code explores the hyperscalper project folder, finds screenshots, writes the blog post content, applies the rewrite skill for style consistency, creates the MDX file with correct frontmatter, and commits the changes.

4. Preview and Publish

   Start the development server to preview the new post.

   Agent output: Blog post appears in the dev server with correct formatting, images, and metadata. Ready to publish.

The Result

• Before: 30 minutes per blog post (manual image copying, writing, formatting)
• After: 30 seconds per blog post (single /blog command)
• Output quality: Posts maintain consistent style, correct frontmatter, and proper image placement
• Iteration speed: If you need to adjust the content, just ask Claude to modify the draft
• Cost: Free (uses Claude Code’s built-in skills system)

Key Takeaways for Prompt Engineering

• Create reusable skills: A well-designed skill eliminates repetitive work across projects.
• Use $ARGUMENTS for flexibility: Pass project paths, topics, or other parameters to the same skill.
• Chain skills together: The /blog skill calls /rewrite to apply your writing style — composable automation.
• Define style guides explicitly: The rewrite skill’s style guide ensures consistent voice across all posts.
• Automate the boring parts: Image copying, frontmatter formatting, and file creation are perfect for automation.

This workflow turns a 30-minute blog post creation process into a 30-second command.

Pricing

FAQ

Q: How many articles can I produce per day?
A: Throughput depends on your API rate limits and the length of articles. For 1500-word pieces, expect ~15-30 minutes per article from start to finish (including image generation). You can batch multiple runs to scale.

Q: Can I use my own existing content as training data?
A: Yes. The skill supports sample articles to learn your style. Provide 3-5 exemplars and Claude will mimic your tone and structure.

Q: Does it really produce SEO-optimized content?
A: The SEO sub-skill analyzes top 10 SERP results and suggests specific improvements. It’s not magic — you still need to review for E-E-A-T (experience, expertise, authoritativeness, trust) — but it gives you a strong foundation.

Q: What if I want to publish on Medium/WordPress/Notion?
A: The output is plain Markdown (article-final.md) plus image files. You can copy-paste into any CMS. Some integrations exist for direct WordPress publishing via MCP servers.

Q: Can I add my own sub-skills or customize the pipeline?
A: Yes. The skill is modular. You can use individual sub-skills (claude-blog:seo-analysis, claude-blog:hero-image) or reorder steps to match your workflow.

Q: Is there a risk of duplicate content?
A: The content is generated fresh per keyword. However, if you run the same keyword twice, outputs will differ but may overlap. Always check for uniqueness before publishing, especially if SEO is critical.
