sleep-masking-dev

SUSPICIOUS/HIGH-RISK skill. It is internally coherent as an evasion-focused research/dev guide, but that purpose itself gives an AI agent offensive stealth capability: sleep masking, anti-forensics, telemetry minimization, and mitigation-aware APC/timer/context chains. No installer, credential, or exfiltration concerns are present in the provided text, so this is not confirmed malware; the primary issue is that it is a high-risk security/exploit skill for agent use.
