Risk Level: SAFEPROMPT_INJECTION
Full Analysis
  • [PROMPT_INJECTION]: Potential for Indirect Prompt Injection via external asset processing.
  • Ingestion points: The skill ingests untrusted data from external sources through the extraction workflows defined in references/extractors/from-website.md (URL analysis), references/extractors/from-pdf.md (PDF brand guide parsing), and references/extractors/from-video.md (video keyframe analysis).
  • Boundary markers: The extraction prompts lack explicit instructions or delimiters to isolate the source data from the analysis instructions, or to ignore any natural language commands hidden within the source documents.
  • Capability inventory: The extracted content is used to populate the style_prompt_full field. This field is subsequently passed as a high-priority instruction to the HeyGen Video Agent connector (references/connectors/heygen-video-agent.md) and other design automation connectors, creating a vector for instructions from the source material to influence agent behavior.
  • Sanitization: The skill does not implement sanitization, filtering, or validation of the extracted design parameters to prevent the inclusion of malicious or unexpected prompt sequences.
