[SAFE]: The skill's primary function is to perform static analysis on local PHP source code files. It uses standard filesystem search tools like grep and glob patterns to identify code structures such as non-readonly classes or mutable properties. No sensitive file access or network operations are involved.
[SAFE]: All command patterns provided are read-only and intended for code auditing. There are no patterns involving remote code execution, package installation from untrusted sources, or privilege escalation.
[SAFE]: No obfuscation, data exfiltration, or persistence mechanisms were detected. The skill follows best practices for a development-focused static analysis tool.
