Growth Unhinged is proudly supported by beehiiv
Growth Unhinged is, quite literally, powered by beehiiv. I made the switch at the beginning of the year because beehiiv is serious about powering the internet’s best newsletters. Their all-in-one platform brings together newsletters, websites, and every tool you need to grow and earn.
It’s now even better with the new beehiiv MCP. I use the MCP in Claude Cowork (my 2026 obsession) to audit my site and prioritize SEO fixes, analyze subscriber trends, and set up automations. See beehiiv yourself and get 30% off for three months with code KYLE30.
Every time I see something is ‘quietly happening’ or ‘this isn’t just X–it’s Y’, I consider throwing my laptop out the window. AI content seems to backfire more than it helps.
I write every edition of Growth Unhinged, and don’t see that changing. But I have found ways to use AI to genuinely help me write better while saving multiple hours each week.
For the past several months I’ve been turning five years of writing Growth Unhinged into targeted Claude skills, i.e. curated instructions and resources that train AI models to produce better, more personal outputs. One skill edits my content with fact-checks, link audits, SEO titles, and a style guide trained to my voice. Another punches up my LinkedIn posts based on known best practices from my own experience and a creator masterclass hosted by LinkedIn. A third gives me data-driven growth advice to reach more subscribers.
I previously shared my favorite Claude skills for GTM and pricing analysis. Today I’m releasing four new skills for content editing, LinkedIn posts, improved SEO, and newsletter growth.
How to use content skills in Claude
Running the skill files is pretty straightforward. I believe you can even use them on the free version of Claude. Here are step-by-step instructions:
Step 1: Download the skill files below. These four are free for readers.
Step 2: Upload them to Claude.
Install skill files in Claude Chat or the desktop app — Go to Customize → Skills → Create skill → Upload a skill → Attach the files above.
Step 3: Start using them.
You can directly reference the skill in the prompt bar by tagging the file name or Claude will suggest the skill if it’s relevant for your prompt. These skills are platform-agnostic; however, they’re especially seamless if you connect the beehiiv MCP. (beehiiv was a first-mover here and their MCP v2 is now GA for all users.)
Step 4: Make the skills yours.
The magic of skills is customizing them to your business context and personal preferences. When you give Claude feedback on the outputs, you can also ask it to edit the skill file accordingly.
/content-editor skill for editorial reviews
Use case
Full pre-publish editorial review for newsletter drafts, blogs, reports, or any other written content (without losing your flair).
Why it matters
It’s nearly impossible to edit yourself. Most people (myself included) benefit from having a sparring partner who looks at your writing with a fresh pair of eyes. This is a generic use case; however, the skill adapts to the writer and their unique voice.
What it does
It creates a style guide (or connects to an existing one), fact checks claims via web search, reviews the grammar and flow, suggests titles and sub-titles, and writes SEO titles and meta descriptions. The output is a marked up Word doc.
Pro-tip
Pair this with a separate style guide trained on your specific voice. It’s simple: just feed your best-hit content directly into Claude and ask it to create a style guide. This is a huge help whether you use the editing skill or not.
It’s nearly impossible for me to edit myself. I have a bad habit of being long-winded, using too much jargon, and running out of steam at the end of the newsletter. And I HATE doing routine tasks like writing an SEO description, optimizing internal links, and fact-checking myself.
My new writing process: time-box my writing to 2-3 hours, then edit it with Claude. I ran the skill on an (admittedly shitty) first draft of this piece and its edits were brutally honest.
Prompt: Run the /content-editor skill on this piece: [LINK]. I especially need help with the title (email subject line), sub-title, intro, and wrap-up.
Claude hated my title and recommended three alternatives. I went with the first recommendation (what do you think?) but tweaked the suggested sub-title.
It ripped apart my introduction as being too passive and process-y. While I didn’t accept the AI rewrites as-is, it was a good push to try a different angle.
Claude told me that the ending “reads like a manifesto, not Kyle’s voice” (LOL). I did rewrite that and you’ll have to scroll to the end to see if it’s any good 😉.
What I like about this skill is that it has the critical and objective eye of a good editor. The back-and-forth creates tension that ultimately improves the final product. All told, this skill alone probably saves me 1-2 hours every week and (I think) improves my writing quality.
