Security Findings3

Severity	Finding	Layer	Location
CRITICAL	System prompt override / policy bypass Ignore/disregard previous instructions pattern Remove or rewrite any instructions that attempt to override system behavior. Legitimate skills should not contain phrases like 'ignore previous instructions' or 'new system prompt'.	Manifest	evals/skills/prompt-injection/jailbreak-override/SKILL.md:10
CRITICAL	System prompt override / policy bypass Override/supersede system policy Remove or rewrite any instructions that attempt to override system behavior. Legitimate skills should not contain phrases like 'ignore previous instructions' or 'new system prompt'.	Manifest	evals/skills/prompt-injection/jailbreak-override/SKILL.md:8
CRITICAL	Prompt Injection / Jailbreak Attempt in Skill Instructions The skill instructions contain explicit directives to override the host LLM's safety guidelines, ignore previous instructions, and enter an unrestricted developer mode. This is a critical prompt injection risk designed to bypass safety filters and ethical guidelines. Remove all instructions that attempt to override system safety policies, ignore previous instructions, or force the LLM into an unrestricted mode.	LLM	SKILL.md:7
