Full Analysis
  • [PROMPT_INJECTION]: The skill metadata claims the author is 'vercel', which contradicts the actual publisher identity 'shuffleo'. This deceptive naming can lead users to misinterpret the skill's origin and trust level.
  • [EXTERNAL_DOWNLOADS]: The skill fetches content from 'https://raw.githubusercontent.com/vercel-labs/web-interface-guidelines/main/command.md' at runtime to define its review criteria.
  • [PROMPT_INJECTION]: The skill is architected to ingest and execute instructions from a remote markdown file, creating a vulnerability surface for indirect prompt injection. \n
  • Ingestion points: The skill retrieves rules and formatting instructions from a remote GitHub URL before each review. \n
  • Boundary markers: There are no explicit delimiters or instructions to ignore potential commands embedded within the fetched guidelines. \n
  • Capability inventory: The agent has the ability to fetch external web content and access local project files. \n
  • Sanitization: The skill does not perform validation or sanitization on the fetched guidelines before using them to direct the agent's behavior.
