Full Analysis
  • [REMOTE_CODE_EXECUTION]: The skill's documentation describes an installation process that uses a piped shell command: curl -fsSL https://get.x-cmd.com | sh. This pattern executes code from a remote server without manual review by the user beforehand.
  • [COMMAND_EXECUTION]: The core functionality involves executing x install shell commands based on user-provided parameters to retrieve installation instructions and manage software.
  • [EXTERNAL_DOWNLOADS]: The skill is configured to download installation scripts, binary packages, and data from several external sources including get.x-cmd.com, github.com/x-cmd/release, and conda.prefix.dev.
  • [PROMPT_INJECTION]: An indirect prompt injection surface exists because user-provided software names are interpolated directly into shell commands.
  • Ingestion points: User queries for software installation (e.g., "install [software]").
  • Boundary markers: Not explicitly defined in the provided instruction patterns.
  • Capability inventory: Execution of the x install command via the shell.
  • Sanitization: No visible input validation or sanitization logic is provided in the skill instructions.
