special-chars-skill

Prevent injection vulnerabilities by treating all input as literals without executing it. This Skill safely handles special characters in arguments, blocking shell metacharacters, command execution patterns, and SQL injection attempts to ensure secure substitution.

Shell metacharacters, HTML/XML entities, quotes, and Unicode inputs require escaping in command execution. This Skill covers sanitization of <, >, &, shell operators, and path traversal patterns to prevent unintended interpretation or execution.

Yes. This Skill enforces literal input treatment, disallowing command execution and character interpretation. It rejects injection patterns and traversal attempts, ensuring user-supplied arguments remain inert data rather than executable code.

This Skill includes coverage for Unicode inputs and common edge cases across shell, HTML, and encoding contexts. It validates and neutralizes special characters that could trigger unintended behavior across different processing pipelines.

Escaping modifies characters; literal input treatment prevents interpretation entirely. This Skill uses the literal approach—disallowing execution and character interpretation—to block injection at the root rather than relying on escape sequences.
