📋 How I Stopped Re-Explaining the Same Task to AI (Claude Skills)

Ok, so today I want to go over Claude Skills, because they fixed a problem I’d been fighting for more than a year.

The problem was this. Every time I wanted the AI to do a task my exact way, I had to explain the whole thing from scratch. Then explain it again the next day. Then again the day after.

A skill ends that. You write the instructions once, save them as a small folder, and the AI uses them on its own whenever that task comes up. Here’s how it actually works, with a real one I built for my business.

The task I run constantly

I do email outreach. Before I can email a lead, I have to turn their raw business name into a short sender name, because email sender names have to be short and clean. So “Joe’s Plumbing & Heating LLC” needs to become something like “Joe’s Team.”

The rules are picky:

• Pull out the brand word, drop the junk (LLC, Inc, “and,” “the”)

• If it’s a person’s name with an apostrophe, keep it (”Joe’s” stays “Joe’s”)

• Add “ Team” on the end

• Keep the whole thing to 13 characters or fewer

• Don’t let weird characters break the file (everything stays UTF-8)

I was pasting these rules into a fresh chat every single time I cleaned a list. Hundreds of words, over and over.

What a skill actually is

A skill is a folder with two things in it. A set of instructions, and, when you want it, real code that does the work.

The instructions live in a file called SKILL.md. The top of it looks like this:

---
name: email-name-cleaner
description: Turns raw business names into short email sender names in
  "Brand Team" format, 13 characters or fewer. Use when cleaning a
  lead list for an email campaign.
---

That description line is the part that matters. It’s how the AI knows when to grab this skill on its own. I never have to say “use the name cleaner.” I say “clean this list” and it picks the right one.

Underneath that, I put the same rules I used to paste every time. Brand word, drop the suffixes, keep the possessive, add “ Team,” cap the length.

The code part is why it’s accurate

Here’s the thing most people miss. A skill can hold actual code, not just written instructions.

For my name cleaner, I don’t want the AI eyeballing 4,000 business names and guessing. Guessing is how you get a row that reads “LLC Team” because it grabbed the wrong word. I want it to run a real script that does the exact same thing every time:

import re

SUFFIXES = {"llc", "inc", "co", "corp", "ltd", "group", "and", "the"}

def clean_name(raw):
    raw = raw.strip()
    # keep a person's name: "Joe's Plumbing" -> "Joe's"
    person = re.match(r"^([A-Za-z]+'s)", raw)
    if person:
        brand = person.group(1)
    else:
        # first real word that isn't junk
        words = re.findall(r"[A-Za-z]+", raw)
        brand = next((w for w in words if w.lower() not in SUFFIXES), words[0])
    return f"{brand} Team"[:13]

Run it on a few names and you get:

Joe's Plumbing & Heating LLC   ->  Joe's Team
Smith Roofing Inc              ->  Smith Team
Blue Ridge Property Mgmt       ->  Blue Team

Same input, same output, every time. No mood, no guessing, no “creative” mistakes on row 3,812. When the AI runs real code instead of doing the work in its head, you can actually trust the result. That’s the accuracy part, and it’s the honesty part too. The AI stops pretending it knows and runs the real thing.

How you attach it

You drop the folder into the conversation. Same motion as attaching a file. After that, the skill sits there ready, and the AI reaches for it on its own when a task matches the description.

You don’t need to code to attach one. You only touch code if you want a script inside it, and you can have the AI write that script for you anyway.

What’s happening under the hood

Quick version, because it’s smarter than it sounds.

The AI doesn’t read your whole skill all the time. At first it only reads that one-line description. That’s tiny. It’s basically scanning the labels on a row of folders.

Only when your request matches does it open the full skill and read the detailed steps. So you can hand it twenty skills and it won’t get clogged up. It reads the labels, opens the one it needs, ignores the rest. That’s why you can stack a pile of them without slowing anything down.

Why this works in more than one place now

The folder format is open, which means it isn’t locked to one product. The same skill I built runs whether I’m in the chat app, in Claude Code, or calling the API. And the format is starting to spread to other AI tools too.

It’s not in every app on earth yet, so I won’t pretend it is. But more tools are picking it up, and you build the thing once either way.

Why you should care

If you run a business, you have tasks you do the same way over and over and keep re-explaining to the AI. The name cleaner is one of mine. You have your own. Your email format. Your report layout. The exact way you sort a messy list of leads.

Write the steps once. Drop in code where the work needs to be exact. Save it as a skill. Then stop explaining it.

Anyway, I hope this is thought-provoking!
