Full Analysis
  • [EXTERNAL_DOWNLOADS]: The skill references external resources for documentation, API specifications, and tool connectivity, all hosted on domains owned by the author (magichourhq).
  • Evidence: References to https://mcp.magichour.ai/, https://docs.magichour.ai/api-reference/openapi.json, and the magichourhq GitHub organization in SKILL.md and references/cover-design.md.
  • [INDIRECT_PROMPT_INJECTION]: The skill processes untrusted external data (titles, transcripts, and outlines) to generate image prompts, which is a common attack surface for indirect prompt injection.
  • Ingestion points: User-supplied video titles, transcripts, and outlines are read in SKILL.md to infer a visual hook.
  • Boundary markers: No specific delimiters or "ignore embedded instructions" warnings are defined for the ingested text.
  • Capability inventory: The skill utilizes image generation and editing tools (edit_image, generate_image) and file upload tools (get_upload_urls).
  • Sanitization: No explicit sanitization of input data is mentioned before it is used to influence the image generation process.
