Critical

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

The content is a dual‑use GraphQL vulnerability hunting guide that provides concrete exploit techniques and payloads (introspection probes, mutations, SSRF, OTP brute-force, alias batching, etc.) which steer a user to perform actions that can bypass authorization and exfiltrate or manipulate data — suspicious steering without clearly malicious framing.
