How to install Hey CLI in Codex

$skill-installer install https://github.com/basecamp/hey-cli/tree/main/skills/heyType this in Codex: $skill-installer is the skill installer built into Codex, and it downloads the skill from GitHub. Restart Codex if the skill doesn't show up. Check the repo README for any setup the skill needs. Source: Codex skills docs.
Or copy the skill folder (the one with SKILL.md) into ~/.agents/skills to use it in every project, or into .agents/skills in a repo to share it with that repo. Codex picks up new skills automatically. (where Codex loads skills)
