Full Analysis
- [REMOTE_CODE_EXECUTION]: The instructions guide the user to install external components and skills using commands like
npx skills add belt-sh/cliandnpx skills add inference-sh/skills@.... These external packages are sourced from repositories not identified as trusted vendors. - [EXTERNAL_DOWNLOADS]: The skill refers to an external installation guide and configuration file at
https://raw.githubusercontent.com/inference-sh/skills/refs/heads/main/cli-install.md. - [COMMAND_EXECUTION]: The skill uses the
Bashtool to executebeltCLI commands for image generation and account management. - [INDIRECT_PROMPT_INJECTION]: The skill constructs commands that interpolate user-provided prompt strings into JSON inputs for AI models. This creates a potential vulnerability where untrusted data could influence the behavior of the generation tools.
- Ingestion points: The
promptfield within the JSON input ofbelt app runcommands. - Boundary markers: Absent; the instructions provide direct interpolation examples without delimiters.
- Capability inventory: The skill can execute shell commands via
Bash(belt *)to perform image generation and app management. - Sanitization: No sanitization or validation of the input prompt strings is implemented within the skill instructions.
