Issue #54: 43,000 Devs Installed This AI Skill in 1 Week

Dear Builders,

Before we get started I want to ask you a question, would you like to get your tool in front of an audience of over 4,000?

If so, I want to feature your skill, project, SaaS or service or whatever you have got going on in this newsletter and on the YouTube channel.

All you need to do is reply to this email with the word ‘yes’ and we can get started on getting you featured. No catch, no cost.

Let’s get into it.

🧠 Skill of the Week

Who Built It: Based on principles from Andrej Karpathy in the forrestchang repo

What It Does:
This is a simple CLAUDE.md skill file that changes how your AI writes code.

It does not add features. It adds rules.

Rules that force better thinking before execution. Instead of letting AI run wild, it slows it down in the right places and tightens how it operates.

How it works in one line:
Task → AI forced to think → Minimal solution → Targeted edits → Verified outcome

Why It’s Incredible:
Most people think they need better prompts.

What they actually need is better constraints.

This skill does not make AI smarter.

It makes it more disciplined.

That changes everything.

You get:

Cleaner outputs
Less debugging
More predictable results

And most importantly:

You stop wasting time fixing AI mistakes.

💸 Weekend Challenge: Start Outreach Now

Challenge:
Install this skill and use it on one real task.

Something simple:

Fix a bug
Build a small feature
Improve an existing workflow

Then compare the output before and after.

Goal:
Record 5–10 short Loom videos showing how this improved the result.

Show:

The messy or typical output
The improved version using the skill
The difference in clarity and quality

You can say something like this:

“Hi [Name], I tested a simple AI workflow that improves how code is written and reduces errors. I recorded a quick example using your setup. Thought this might be useful.”

You are not selling the skill. You are showing the outcome. Most people try to get more out of AI by doing more.

Remember

Better builders do it by adding constraints.

This is one of those constraints.

Everything else is noise.
