Full Analysis
  • [EXTERNAL_DOWNLOADS]: The skill connects to Grammarly's official API endpoint (api.grammarly.com). As a well-known service provider for writing assistance, this external communication is expected and safe within the context of the skill's functionality.
  • [PROMPT_INJECTION]: The skill acts as a bridge for document text, creating an indirect prompt injection surface.
  • Ingestion points: Untrusted text enters the system via the scoreDocument and batchScore functions in src/grammarly/scoring.ts.
  • Boundary markers: The provided code does not implement specific delimiters or instructions to the LLM to ignore instructions embedded within the processed document text.
  • Capability inventory: The skill uses fetch to send data to the external Grammarly API.
  • Sanitization: The implementation includes a check to ensure documents contain at least 30 words, adhering to API requirements.
