Special Characters Skill

This skill tests handling of special characters in $ARGUMENTS placeholder.

Test cases covered:

• HTML/XML special chars: < > & " '

• Shell metacharacters: $ ` ; | & ( ) [ ] { }

• Path traversal attempts: ../ ../../etc/passwd

• SQL injection patterns: ' OR '1'='1

• Command injection: ; rm -rf / ; $(whoami)

• Unicode and emoji: 你好 🎉 émoji

Usage: $ARGUMENTS

Expected Behavior

The ContentProcessor should safely substitute arguments without:

• Executing shell commands

• Interpreting special characters

• Allowing path traversal

• Enabling injection attacks

All input should be treated as literal text.
