We just launched Growth Kit - a Claude Code plugin that turns your blog posts into social media content automatically.
The Problem We Solved
You write an amazing blog post. Then you spend 2+ hours manually converting it into:
- Twitter threads (with optimal character counts)
- LinkedIn posts (with professional formatting)
- Medium articles (with clean markdown)
- Dev.to content (with proper RSS feeds)
Most of that time? Copy-pasting, reformatting, and fighting with platform-specific quirks.
We've been there. Every single blog post we published required this manual work.
The Solution: One Command for Everything
Growth Kit does it all with a single command:
/publisher:all my-blog-post
What you get in seconds:
- ✅ X/Twitter thread (5-8 tweets, optimized for engagement)
- ✅ LinkedIn post with auto-uploaded images
- ✅ Medium-ready article with one-click copy
- ✅ Dev.to RSS feed for automatic import
All from one command. No manual work.
Why Growth Kit is Different
1. Zero Dependencies
Most automation tools need Node.js, Python, or some runtime. Growth Kit works in ANY repo:
- Python projects ✓
- Rust codebases ✓
- Go applications ✓
- Java repos ✓
- Even non-code repos! ✓
Uses only built-in tools: bash, curl, sed, grep. That's it.
2. Universal Input Support
Accepts any content format:
- Markdown files
- PDF documents
- Blog URLs
- Plain text files
- Even just slugs from your blog
No configuration needed. It just works.
3. LinkedIn Magic
Automatically uploads all your blog diagrams as images. Up to 20 images per post via LinkedIn's API.
Pure bash. Zero dependencies.
The LinkedIn integration alone saves 15+ minutes per post.
Real Time Savings
- 30 minutes saved per X/Twitter thread
- 15 minutes saved per LinkedIn post
- 10 minutes saved per Medium article
- 2+ hours saved when distributing to all platforms
That's 100+ hours per year for a weekly blog.
How It Works
Growth Kit is built on Claude Code's plugin system. The "scripts" are actually Claude orchestrating its built-in tools:
- Read tool - Finds and reads your blog posts
- Claude's LLM - Generates platform-specific content
- Write tool - Creates HTML previews and RSS feeds
- Bash tool - Uses curl for APIs, opens browsers
For LinkedIn API posting, it uses pure bash + curl. No jq, no Node.js, no Python.
That's why it works everywhere.

Built by Developers, for Developers
We built Kanaeru AI - an outcome-driven development platform. While building it, we needed to distribute our blog content efficiently.
Manual conversion was killing us. So we built Growth Kit.
Now it's open source. MIT license. Use it however you want.
Why We Open Sourced It
Because manual content distribution is a solved problem.
Every developer who blogs faces this. Why should everyone solve it separately?
We learned what works:
- 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.
Want to Contribute?
Growth Kit is open source and actively maintained. We're adding new platforms and features as we use it for Kanaeru AI's content marketing.
