brew install claude-code
==> Caveats
Claude Code's auto-updater installs updates to `~/.local/bin/claude` and
not to Homebrew's location. It is recommended to disable the auto-updater
with either `DISABLE_AUTOUPDATER=1` or
`claude config set -g autoUpdates false` and use
`brew upgrade --cask claude-code`.
