Part 1

Custom GPTs are going away

What's replacing them, and why it matters for you.

What's next

Custom GPTs are being replaced by Skills and Plugins

Retiring

Custom GPTs

Instructions, knowledge and a job, locked inside one app.

Skills

Reusable instructions for one specific job. This is what we build tonight.

Plugins

A bundle that installs Skills, tools and app connections in one step.

Why Skills win

Skills work across platforms

One Skill folder.
ChatGPT and Claude.

Both platforms support Skills, so what you build tonight travels with you.

Plain files you own

Move between platforms without rebuilding

Share with clients or a whole team

Sell it as a download

Built Custom GPTs before?

Good. You're not starting over.

You already know how to give AI instructions, knowledge, examples and a job. The format is changing. The underlying expertise still has value.

Plugins at a glance

A Plugin is a package that holds Skills

One install, everything included

Skills

App connectors

Commands

Settings

Skills are the expertise. A Plugin is how you ship several Skills plus tools together.

Coming up: Plugins get their own full workshop.

Part 2

How a Skill works

The concept, the file and the five-step process.

The difference

A prompt versus a Skill

A prompt

Typed once. Gets one result. Lives in your notes and depends on you remembering it.

A Skill

Saved once. Runs the same process every time. Loads itself when the job comes up.

Anatomy of a Skill

A Skill is a folder with one key file

sales-call-prep/

SKILL.md

Name, description and step-by-step instructions

Required

references/

Knowledge files, examples, templates to follow

Optional

scripts/

Small bits of code the Skill can run

Optional

assets/

Images, logos, files it hands back

Optional

Behind the scenes

How the AI decides to use your Skill

Step 1

You ask for help with a job

Step 2

The AI scans every Skill's name and description

Step 3

It finds a match and opens SKILL.md

Step 4

It pulls reference files only when needed

The description does the heavy lifting. If it's vague, the Skill never gets picked.

Inside SKILL.md

The description is the trigger

---

name: sales-call-prep

description: Prepares a one-page brief before a sales call. Use when someone mentions an upcoming call, a discovery call or researching a prospect.

---

# Instructions
