4. Configure (Optional - LinkedIn API Only)

X/Twitter, Medium, and Dev.to need ZERO configuration - they just work!

For LinkedIn API automated posting (optional):

cp .env.example .env
# Edit .env with your LinkedIn app credentials from https://www.linkedin.com/developers/apps

LINKEDIN_CLIENT_ID=your_client_id
LINKEDIN_CLIENT_SECRET=your_secret
BLOG_BASE_URL=https://yourblog.com

Without API setup: LinkedIn command still generates the post content - you just copy-paste manually.

4. Use It

# Generate X/Twitter thread from your blog post
/publisher:x my-blog-post

# Or from any markdown file
/publisher:x path/to/article.md

# Or from a URL
/publisher:x https://yourblog.com/article

# Generate Dev.to RSS feed (one-time setup)
/publisher:devto

# Create content for ALL platforms at once
/publisher:all my-blog-post

That's it! Growth Kit will:

1. Find and read your content
2. Generate platform-specific formats
3. Open preview files in your browser

Note: All commands work in ANY repo type. Claude generates everything using only Read, Write, and Bash tools!

How It Really Works Under the Hood

No magic, no dependencies - just Claude using its built-in tools:

1. Read tool: Finds and reads your blog posts (markdown, PDF, URL)
2. Claude's LLM: Generates platform-specific content from your blog
3. Write tool: Creates HTML previews, RSS feeds, etc.
4. Bash tool: Uses curl for APIs, open for browsers

For LinkedIn API (optional):

• Uses curl to call LinkedIn REST API
• Pure bash/curl - works in Python repos, Rust repos, anywhere!
• No jq, no Node.js, no npm

That's it! The "scripts" are actually just Claude orchestrating its tools based on the command instructions.

Why Growth Kit?

Built by Kanaeru Labs while building Kanaeru AI (our product).

We needed to distribute our blog content across platforms efficiently. So we built this.

Key insights we learned:

• X/Twitter threads need hooks, not summaries
• LinkedIn needs data points, not fluff
• Medium needs clean markdown, not complex HTML
• Manual conversion wastes hours every week

Now you can benefit from what we learned.

---

Advanced Usage

Custom Blog Structures

Growth Kit adapts to YOUR blog structure:

✅ Gatsby blogs (content/blog/)
✅ Next.js blogs (posts/)
✅ Astro blogs (src/content/)
✅ Hugo blogs (content/posts/)
✅ Custom setups (any markdown structure)

No configuration required. It just works.

Multi-Language Blogs

If you have both English and Japanese content:

/publisher:x my-post    # Auto-detects language from path
/publisher:x my-post ja # Force Japanese
/publisher:x my-post en # Force English

---

Troubleshooting

Q: Command not found? A: Make sure you installed the plugin: /plugin install publisher

Q: Can't find my blog post? A: Use full path: /publisher:x src/content/blog/my-post.md

Q: Works in Python/Rust/Go repos? A: Yes! ALL commands work in any repo type. Claude uses only standard tools (bash, curl, sed) - no language-specific dependencies.

Q: Want different output format? A: The commands are just markdown files in /commands. Edit them!

Q: Need help? A: Open an issue: https://github.com/kanaerulabs/growth-kit/issues
