Scan a source tree for command-injection vulnerable patterns: shell=True calls in Python subprocess, os.system / os.popen with interpolated strings, Node childprocess.exec with template literals, Ruby backticks / Kernelsystem / Kernelexec with interpolation, Go exec.Command with shell wrapping, PHP system / passthru / shellexec / backticks with $-interpolation, Java Runtime.exec with concatenated args. Use when: pre-commit gate on code that calls out to shell utilities, audit of file-processing / archive-handling / image-conversion code, post-bug-report investigation for "we shell out to a tool." Threshold: any shell-invocation API called with a string that contains a variable interpolation, OR shell=True with anything other than a fixed literal. Trigger with: "scan command injection", "shell=True audit", "find exec calls", "check os.system".

Quick start
Copy the install prompt. Use the green button above this README.
Send it to your agent. Paste it into your coding agent’s chat and send.
Review the setup. Your agent checks the skill’s instructions, requirements, and installation scope.
