What: Native detection and handling of Homebrew-managed installations How to use:
# When installed via Homebrew, update with:
brew upgrade claude-code
# Claude Code will detect this and show appropriate instructions
claude update
# Output: "Claude is managed by Homebrew."
# "To update, run: brew upgrade claude-code"Details:
- Detects Homebrew installations by checking for
/Caskroom/in executable path - Prevents self-update attempts that could conflict with Homebrew management
- Shows in-session update notifications with correct "brew upgrade" command
- Polls npm registry every 30 minutes to check for updates
- Configuration tracking automatically skipped for package-manager installations
- Evidence: Homebrew detection
