CRITICAL E006: Malicious code pattern detected in skill scripts.

• Malicious code pattern detected (high risk: 1.00). This content contains explicit, actionable instructions for creating reverse shells, executing remote commands, and transferring files without authentication—clear backdoor and data-exfiltration patterns that can be used maliciously.

MEDIUM W013: Attempt to modify system services in skill instructions.

• Attempt to modify system services in skill instructions detected (high risk: 1.00). The prompt explicitly instructs setting up listeners and reverse shells (including spawning /bin/bash via -e or mkfifo), and transferring/extracting files to/from the host — actions that enable remote code execution and arbitrary modification of the machine's filesystem/state.
