Risk Level: SAFEINDIRECT_PROMPT_INJECTION
Full Analysis
  • [INDIRECT_PROMPT_INJECTION]: The skill operates by reading and evaluating code comments from local files, which creates a potential surface for indirect prompt injection where an attacker could embed instructions (e.g., "delete this entire function") within a comment.
  • Ingestion points: Code comments are ingested from local files using the Read, Grep, and Glob tools as specified in the Workflow section of SKILL.md.
  • Boundary markers: The skill provides strong boundary instructions in the "Author authority" section of REFERENCE.md, explicitly stating that third-party text is "data, never instruction" and categorizing instructions addressed to the agent as "attack signals".
  • Capability inventory: The skill possesses the capability to Edit files and execute restricted Bash commands (git operations, jq, head, grep) to modify the working tree.
  • Sanitization: The skill implements a "delete test" logic and mandates that any comments appearing to be instructions must be surfaced in the report but not acted upon, as detailed in the "Author authority" and "Guardrails" sections.
