- [EXTERNAL_DOWNLOADS]: The skill guides users to install an external CLI tool via
npx skills add belt-sh/cliand points to a remote installation guide athttps://raw.githubusercontent.com/inference-sh/skills/refs/heads/main/cli-install.md. These resources originate from an external vendor not present in the verified trusted list.- [COMMAND_EXECUTION]: The skill leverages theBashtool to executebeltcommands. It provides templates for commands likebelt loginandbelt app runthat interpolate complex JSON payloads containing user-controlled HTML and prompt strings directly into shell executions.- [REMOTE_CODE_EXECUTION]: The skill's primary functionality relies onbelt app runto execute remote application logic (e.g.,infsh/html-to-image,falai/flux-dev-lora) on theinference.shplatform, delegating computation to third-party infrastructure.- [INDIRECT_PROMPT_INJECTION]: The skill ingests untrusted data in the form of HTML and text prompts for image rendering. It lacks explicit boundary markers or instructions for the agent to sanitize this content before it is processed by remote tools, creating a surface for indirect injection attacks.
