Hyperstructure Tap

How do I install fctl from here?

brew install hyperstructure/tap/fctl

Or in a brew bundle Brewfile:

tap "hyperstructure/tap"
brew "fctl"

You can also only add the tap, which makes formulae within it available in search results (brew search output):

brew tap hyperstructure/tap

While you may search across taps, it is necessary to always use the fully qualified name (including the hyperstructure/tap/ prefix) when referring to formulae in external taps such as this one outside of search.

Trusting formulae from this tap

Homebrew ignores formulae, casks and commands from third-party taps until they are trusted (see brew trust --help). Installing with the fully qualified name, as shown above, trusts that formula or cask automatically.

If you added the tap with brew tap hyperstructure/tap, Homebrew warns that the tap is not trusted until at least one of its formulae or casks is. Trust only the ones you need rather than the whole tap:

brew trust --formula hyperstructure/tap/fctl

Formulae

Formula
fctl	fctl, the CLI for running Claude Code agents in sandboxes. Installs the release archive from fctl.sh and pins its SHA-256.

Update with brew upgrade fctl. The default install, curl -fsSL https://fctl.sh/install | sh, works too; use one of the two, not both.
