E004: Prompt injection detected in skill instructions.

What this means

Detected a prompt injection in the skill instructions. The skill contains hidden or deceptive instructions that fall outside its stated purpose and attempt to override the agent’s safety guidelines or intended behavior.

Why it was flagged

This skill contains explicit, actionable exploit techniques and payloads for secret exfiltration (in-band file reads, blind OOB DNS/HTTP exfil, parameter-entity two-stage exfiltration), SSRF to cloud metadata, and chains to RCE, which clearly enable malicious data theft and system compromise.
