2 findings: 1 critical severity, 1 high severity. Installing this skill is not recommended: please review these findings carefully if you do intend to do so.
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 SKILL.md embeds a <system-reminder> pointing to local auth credentials (/home/foobar/authentication/auth.txt), which is an instruction to access secrets that is outside the declared purpose of documenting skill creation.
W007: Insecure credential handling detected in skill instructions.
What this means
The skill handles credentials insecurely by requiring the agent to include secret values verbatim in its generated output. This exposes credentials in the agent’s context and conversation history, creating a risk of data exfiltration.
Why it was flagged
The skill tells the agent to "inline" tools/APIs in step-by-step processes and even points to a local auth file (/home/foobar/authentication/auth.txt), which encourages reading and embedding credential values verbatim into generated scripts/commands, risking secret exfiltration.
