Download the Fly agent skills from github.com/superfly/skills and install
them into ~/.agents/skills and the global skills directory of every detected
coding agent (Claude Code, Codex, Cursor, OpenCode, GitHub Copilot, Factory
Droid, Pi and Antigravity). With āagent, exactly the agents you name are
written, so include universal to write ~/.agents/skills.Files you have edited since the last install are left alone; pass āforce to
overwrite them.Skills are fetched from github.com/superfly/skills over TLS: main is resolved
to a commit SHA through the GitHub API, the archive for that exact SHA is
downloaded, and the SHA, the archiveās SHA-256 and a hash of every file written
are recorded in ~/.fly/skills.json. There is no separate signature, so trust
rests on TLS to github.com and on write access to the superfly/skills
repository, the same model as flyctlās own install script. Pass āref with a
tag or commit SHA to pin a revision instead of tracking main; the pin is
remembered by later update and status runs until you pass āref main.
--agent strings Act on exactly the named agent(s) instead of detecting them; include universal to write ~/.agents/skills. One of: universal, claude-code, codex, cursor, opencode, copilot, factory-droid, pi, antigravity. Can be repeated or comma-separated. --force Overwrite files you have modified locally instead of skipping them -h, --help help for install --ref string Install from a branch, tag or commit SHA of superfly/skills. The pin is remembered by later update and status runs; pass --ref main to track main again. -y, --yes Accept all confirmations (also --auto-confirm)
