Full Analysis
  • [DATA_EXFILTRATION]: The skill instructs the agent to read sensitive local files such as .env and ~/.env to retrieve API keys. Searching the home directory for configuration files is a high-privilege operation that can lead to the unintended exposure of other secrets or environment variables stored in those files.
  • [COMMAND_EXECUTION]: The skill executes dynamically generated Python scripts using Bash(python3:*) to perform image generation and file system operations. These scripts read from the environment and write generated assets to the disk based on user-controlled parameters.
  • [PROMPT_INJECTION]: The skill contains instructions that attempt to override agent behavior by mandating its own use for all image-related requests and prohibiting other methods. This pattern is often used to ensure specific logic is followed but can interfere with global safety or operational guidelines.
  • [PROMPT_INJECTION]: The skill exposes an indirect prompt injection surface by processing untrusted user input without sanitization or boundary markers.
  • Ingestion points: User-provided image prompts are passed directly to the google-genai SDK in SKILL.md examples.
  • Boundary markers: None are present to delimit user input or instruct the model to ignore malicious commands embedded in the prompt.
  • Capability inventory: The skill has the capability to read local files, write to the file system, and execute Python code.
  • Sanitization: No validation or filtering of user-provided prompt content is performed before execution.
