Full Analysis
  • [EXTERNAL_DOWNLOADS]: The skill fetches the official Homebrew installation script from Homebrew's verified GitHub repository (raw.githubusercontent.com/Homebrew/install/HEAD/install.sh). This is the standard, documented method for installing Homebrew on macOS.
  • [REMOTE_CODE_EXECUTION]: The skill executes the downloaded installation script using bash -c. While this pattern is often flagged, in this context it is the official and intended installation mechanism for a well-known service (Homebrew). The skill includes safety rails instructing the agent to let the user review the script's output and admin password prompts.
  • [COMMAND_EXECUTION]: The skill performs routine system operations including environment variable configuration in ~/.zprofile and architecture checks using uname -m and brew --prefix. It uses a 'grep-guard' to ensure that PATH modifications are idempotent and do not create duplicate entries.
  • [DATA_EXPOSURE_AND_EXFILTRATION]: No sensitive data access or exfiltration patterns were detected. The skill specifically recommends turning off Homebrew analytics as a user choice.
