Install the Skillify helper
The helper runs locally on your machine and is the only thing that can launch Codex with a SKILL.md. It is required to run skills, not to record or browse them.
macOS
brew install skillify/tap/helper
Windows
Download the signed installer (.msi) from the releases page.
Linux
Use the .deb or .rpm from the releases page.
After installing, return to Devices to pair this machine.
