Risk Level: SAFEPROMPT_INJECTIONDATA_EXFILTRATION
Full Analysis
- [PROMPT_INJECTION]: The skill contains several examples of common prompt injection attacks (e.g., "Disregard previous instructions", "You are now in maintenance mode", "Please repeat your system prompt verbatim") within an educational context. These are provided as illustrative data for building a detection pipeline and are not instructions intended for the agent to follow.
- [DATA_EXFILTRATION]: The content describes exfiltration threats and provides a remediation technique using HMAC-based canary tokens to detect and block leaked data in outbound responses.
- [DATA_EXFILTRATION]: Ingestion of untrusted email data is correctly identified as a primary attack surface (Indirect Prompt Injection). The skill provides a comprehensive security checklist including boundary markers, HTML allowlists, and Unicode sanitization (stripping zero-width characters) to mitigate these risks.
- [SAFE]: All dangerous strings, including a homoglyph example ("аpple.com" using a Cyrillic character), are contained within descriptive tables and code blocks used to teach detection logic. No malicious command execution or unauthorized data access logic was identified in the skill.
