Risk Level: SAFEPROMPT_INJECTION
Full Analysis
  • PROMPT_INJECTION (LOW): The specification defines a framework for Indirect Prompt Injection.
  • Ingestion points: The framework relies on the agent reading and processing SKILL.md files, which include both metadata (name, description) and a markdown body containing instructions.
  • Boundary markers: Metadata is delimited using XML-like tags in the system prompt as described in skill-client-integration.md. However, the markdown body is read directly by the agent (e.g., via cat) without inherent boundary markers to prevent the agent from following malicious instructions embedded in the data.
  • Capability inventory: The guide explicitly describes agents executing shell commands and using tools based on the instructions discovered in these skills, creating a path from untrusted input to execution.
  • Sanitization: The validation script (quick_validate.py) includes basic sanitization by disallowing angle brackets (<, >) in the description to prevent tag-injection in the XML prompt structure, but no sanitization is applied to the instructional markdown body.
