We build software with Claude every day, and we teach it our methods as skills: folders of instructions and scripts that Claude reads when a task calls for them. These three come from our own projects. Take them, use them, change them. Free, MIT licensed, no sign-up.
The rulebook and monthly check we use to get our own sites named by ChatGPT, Claude, Perplexity and Google’s AI answers: what moves citations, what doesn’t, and how to measure it without fooling yourself.
Captures, measures and checks a site in Chrome, in Safari’s engine and in a real iPhone’s Safari, then lays the before and after side by side. Layout seen only in Chrome hasn’t been checked.
Claude drives Final Cut Pro, Motion, Compressor and Pixelmator Pro in the background: it builds timelines, titles and print-ready art, renders and encodes them, and checks every file it makes.

A skill is a folder with a SKILL.md file of instructions, and sometimes scripts and reference files, that Claude reads when a task matches what the skill is for. Skills work in Claude Code, in the Claude apps and through the API.
In Claude Code, add our marketplace once with /plugin marketplace add Avant-Concepts-LLC/claude-skills, then install any skill from it by name, or unzip a download into ~/.claude/skills/. The AEO skill also works on claude.ai and in the Claude desktop app: with code execution turned on, go to Customize, then Skills, choose Create skill, then Upload a skill, and pick the zip. The other two need Claude Code on a Mac.
Yes. They are MIT licensed: use them, change them, and ship them in your own work. There is nothing to sign up for.
No. They are instructions and scripts that run on your machine. Anything they fetch, they fetch from the sites you point them at.
No. Final Cut Pro, Motion, Compressor and Pixelmator Pro are Apple’s apps, and these skills are not affiliated with or endorsed by Apple. They work with the apps you already have installed and include none of Apple’s own files.
Avant Concepts, an AI software studio in Jacksonville Beach, Florida, founded by Ben Subercaseaux. We use every one of these on our own products.
We write custom skills and agents: we learn how your team does a task, write it down so Claude can do it, and test it on your real cases until it does the job the way your best person would.
