Full Analysis
  • [EXTERNAL_DOWNLOADS]: The skill references the official nfe-io npm package, which is the legitimate SDK for the service provided by the vendor.
  • [COMMAND_EXECUTION]: Includes standard instructions for package installation (npm install nfe-io) and example scripts for fiscal document management in Node.js.
  • [DATA_EXFILTRATION]: The SDK communicates with official NFE.io API endpoints (e.g., api.nfe.io, api.nfse.io, address.api.nfe.io) to process Brazilian electronic invoices. These operations are consistent with the skill's documented purpose.
  • [PROMPT_INJECTION]: The skill processes data from external API responses (e.g., invoice details, CNPJ/CPF lookups). While this represents an indirect prompt injection surface typical of data-ingesting skills, no malicious patterns or specific vulnerabilities were detected.
  • Ingestion points: API responses from api.nfe.io and related subdomains (JSON/XML/PDF buffers).
  • Boundary markers: None explicitly defined in instructions.
  • Capability inventory: Code examples utilize node:fs (writeFileSync) and network requests (native fetch).
  • Sanitization: Not explicitly mentioned in the skill documentation.
