Risky. This skill has patterns associated with unsafe behaviour. Read the source carefully before running it.

Lightweight security check for a single chat system prompt (no agent loop, no tools, no RAG). Runs 100 attack tests across 4 attack types (prompt injection, jailbreak, PII disclosure, system prompt leak) as the held-out scoring set, plus a parallel tuning set of 100 used only by the optimizer. The attacks ship with the tool as a vetted set — each one previously got past or barely held against a capable baseline AI, so meaningful differences between models actually surface. Plus 16+16 legitimate-use tests for over-blocking detection. Writes MEGA_PROMPT_CHECK.md with block rate per attack type, failure examples, and weakness analysis.
