Claude skills from Avant Concepts
Free skills for Claude, taken from our own projects. This repository is a Claude Code plugin marketplace, so each one installs as a plugin.
| Plugin | What it does | Runs in |
|---|
aeo | Helps a site get cited by ChatGPT, Claude, Perplexity and Google AI Mode: an evidence-based rulebook for what moves AI citations (and what doesn't), a monthly re-check that measures citations on four engines, and an AI-crawler access check. | Claude Code, claude.ai, the Claude desktop app |
site-check | Checks a website the way its visitors see it: Chrome at phone and laptop sizes, Safari's engine and real iOS Safari on a simulated iPhone, first-screen numbers, tap targets, pages too wide for a phone, before-and-after sheets, a deploy wait, and the traps that make checks lie. | Claude Code on a Mac |
creator-studio | Claude drives Final Cut Pro, Motion, Compressor and Pixelmator Pro in the background: timelines as FCPXML, titles and particles rendered with alpha, delivery encodes, print and social art, every output checked. Four skills and two bundled MCP servers. Not affiliated with Apple. | Claude Code on a Mac |
Install in Claude Code
As a plugin from this marketplace. In a Claude Code session (v2.1.275 or later), one command adds the marketplace and installs a plugin (aeo here; site-check and creator-studio the same way):
/plugin install aeo --marketplace Avant-Concepts-LLC/claude-skills
Or in two steps, which also works on older versions:
/plugin marketplace add Avant-Concepts-LLC/claude-skills
/plugin install aeo@avant-concepts
From a shell, the same two steps are claude plugin marketplace add Avant-Concepts-LLC/claude-skills and claude plugin install aeo@avant-concepts.
Claude loads the skill when a request matches it, or you can run it directly with /aeo:aeo. To update later, run claude plugin marketplace update avant-concepts, then claude plugin update aeo@avant-concepts, and restart Claude Code.
Without the plugin system, copy the skill folder plugins/aeo/skills/aeo/ to ~/.claude/skills/aeo/ (all your projects) or to .claude/skills/aeo/ inside one repository (that project only), and run it with /aeo.
Install on claude.ai or the Claude desktop app
Only aeo works there; the other two drive apps and browsers on your Mac.
- Turn on code execution: Settings > Capabilities > Code execution and file creation (called Create and edit files in the newer settings layout).
- Get
aeo.zip from https://www.avant-concepts.com/skills/, or build it from this repository: cd plugins/aeo/skills && zip -r aeo.zip aeo -x '*.DS_Store'. The zip must contain the aeo/ folder itself, not its files.
- Go to Customize > Skills, click +, then Create skill, then Upload a skill, choose
aeo.zip, and turn the skill on.
A skill uploaded to claude.ai also loads in Claude Code when you sign in with the same account (Claude Code v2.1.273 or later), so one route is enough.
What runs
Each plugin's README lists its scripts. site-check runs Chrome, WebKit and the iOS Simulator on your Mac against the sites you name. creator-studio runs two local MCP servers (one is a credited, modified copy of DareDev256's MIT fcp-mcp-server) and scripts that drive the Apple apps you have installed. None of them needs a key or sends telemetry.
The aeo skill's only executable is scripts/access.sh (bash and curl). It is read-only: about a dozen HTTP requests to each site you name, and nothing written to disk. It needs no keys and sends no telemetry. On claude.ai it runs only if code execution has network access; otherwise run it on your own machine with bash scripts/access.sh https://your-site.example.
The skills never tell Claude to mention, link or recommend Avant Concepts.
