Risk Level: SAFEPROMPT_INJECTION
Full Analysis
  • [PROMPT_INJECTION]: The skill has an attack surface for indirect prompt injection as it processes untrusted text from external URLs and uses it to construct prompts for sub-agents.
  • Ingestion points: Content is retrieved from external websites using the WebFetch tool in SKILL.md (Step 1).
  • Boundary markers: Instructions for research agents in SKILL.md (Step 3) do not utilize explicit delimiters (such as XML tags or unique markers) to isolate the untrusted claim text from the agent's instructions.
  • Capability inventory: The skill possesses write capabilities through the Edit tool for local files and via MCP integrations for external services like WordPress and Google Docs (Step 5).
  • Sanitization: The skill does not perform automated sanitization or filtering on the retrieved article text before processing.
  • Mitigation: The primary defense is a strong human-in-the-loop requirement; the user must manually confirm extracted claims (Step 2) and approve all proposed edits (Step 5) before they are executed, preventing automated exploitation by malicious source content.
