Security checks for vulnerabilities and agentic risk

Overview

This is a low-impact humor persona skill with no executable code, tools, credential use, persistence, or hidden data access.

Install only if you want intentionally chaotic meme slang and edgy roast-style humor available to your agent; avoid using it in professional or audience-sensitive contexts unless you explicitly want that tone.

Vague Triggers

Medium
Confidence
91% confidence
Finding
This markdown file describes the skill's purpose and persona but does not define when it should activate, what exact trigger phrases invoke it, or any exclusion conditions. Without specific scope or negative examples, the invocation criteria are overly open-ended and could cause unintended activation for general humor-related requests.
