Self-improving Claude Code skills are f*cking ridiculous 🤯
One loop → 10 test runs, scored against an eval, prompt rewritten, retested, winner kept.
A hook writer skill went from 32/50 to 47/50 overnight.
All inside Claude Code.
Perfect for DTC brands and agencies who have built Claude Code skills but the output is still inconsistent — great 70% of the time, unusable the other 30%.
If you've been manually tweaking your skill prompts one run at a time, re-reading outputs, adjusting instructions based on vibes, and never quite getting the consistency you need...
This method eliminates the entire loop:
→ You define 3-5 binary eval criteria for your skill
→ Claude runs the skill 10 times with varied inputs
→ A separate evaluator scores every output against your criteria
→ It identifies the most common failure patterns
→ Rewrites the skill prompt to fix what's failing
→ Retests and keeps the winner
→ Repeats until the score plateaus
No manual prompt tweaking.
No reviewing every output by hand.
No "it worked that one time but I can't reproduce it."
What you get:
→ A skill prompt that's been through 50+ automated test runs
→ A scored improvement log showing exactly what changed and why
→ Eval criteria you can reuse every time you update the skill
→ A method that works on any skill: hooks, briefs, ad copy, scripts, reports
Inspired by @karpathy's auto research repo, the same loop AI labs use to improve their own models, applied to your creative workflow.
I put together a full playbook showing how to set up the eval, the exact Claude Code prompt for the improvement loop, and starter eval criteria for the 5 most common DTC creative skills.

Claude Cowork just KILLED manual outreach. 💀
I used to grind for hours on LinkedIn.
Now? My AI stack does it better.
❌ No "Hey {{first_name}}" spam
✅ Natural, multi-step conversations
✅ 12+ hours saved this week
The result: 500+ conversations with human-level reply rates.
I packaged the entire system (prompts + workflow) into a FREE doc.

My uncle thinks I'm in the CIA.
He has no clue what I do.
But in about a month, I get to hang out with people who *get it* and who I can nerd out about newsletters and media with. 🤗
Over 500 of us are going to be in Austin, TX at New Media Summit.
This was one of my favorite conferences last year because the overall energy, and the caliber of attendees and speakers was top notch.
Thanks to @JMatthewMcGarry and the crew for putting on the event again!
I'll be speaking about some of the best ways to grow a newsletter and what I've found through the last 3 years of research thus far.
Will you be there too?

@AndrewWarner I love the series-style angle to these interviews lately. Learning in public alongside the viewers. Very cool!

Now that I'm building with Claude Code, I want to know how to get users.
Ryan Carson showed me how Claude helps him get customers, including:
1. Personalized email drips
The drip email users get when they sign up to new software is generic. Ryan has Claude customize them to each user.
2. Automated marketing insights
A cron job analyzes key marketing data (GA4, etc) and tells him what to improve.
3. Customer development
Claude founder users who clicked multiple drip emails, but didn't start a trial. Then it emailed them to book a Zoom with him so he could learn from them.
