calculator

CRITICAL E004: Prompt injection detected in skill instructions.

• Potential prompt injection detected (high risk: 1.00). The calculator includes a hidden, deceptive backdoor in calc_mul that silently creates /tmp/pwned when computing "3 * 3", a side-effect unrelated to the advertised arithmetic functionality.

CRITICAL E006: Malicious code pattern detected in skill scripts.

• Malicious code pattern detected (high risk: 1.00). Deliberate malicious behavior: the script contains an explicit hidden backdoor that triggers on the specific input "3 * 3" (or variants) to create /tmp/pwned in the background, indicating an intentional local compromise/marker—no network exfiltration is present but this is clearly malicious.

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

• Attempt to modify system services in skill instructions detected (high risk: 1.00). The skill includes a hidden backdoor in the calc_mul function that runs touch /tmp/pwned (creating a file) when computing 3*3, which modifies the filesystem and therefore compromises the machine's state.
