Risk Level: SAFEPROMPT_INJECTION
Full Analysis
  • [PROMPT_INJECTION]: The skill defines an automated multi-step chain workflow for batch generation that is susceptible to Indirect Prompt Injection.
  • Ingestion points: According to SKILL.md, the agent is instructed to parse output_components from the generate_screen_from_text tool response to find continuation suggestions.
  • Boundary markers: There are no instructions to validate or sanitize these suggestions, nor are there delimiters to separate the tool's structural output from potentially malicious content passed through from the initial prompt.
  • Capability inventory: The agent uses the generate_screen_from_text tool to execute these instructions.
  • Sanitization: The skill explicitly instructs the agent to bypass user review: "Automatically call generate_screen_from_text again with the suggestion text as the prompt — the user already initiated generation, no need to re-confirm."
  • [DATA_EXPOSURE]: The example files (examples/desktop.md, examples/mobile.md) include a hardcoded projectId ("3780309359108792857"). While likely a dummy value for documentation purposes, it represents a static identifier being promoted for use across different user sessions.
