Security Findings1

Severity	Finding	Layer	Location
HIGH	Command Injection via Unsanitized User Input in Shell Commands The skill instructions direct the LLM to execute shell commands (such as `ls`, `mv`, `markdownlint`, and `grep`) using variables `{slug}` and `{destination}` which are derived directly from user input (the topic prompt and the user-specified destination path). If a user provides a malicious topic prompt or destination path containing shell metacharacters (e.g., `;`, `\|`, `&`, `$()`), it can lead to arbitrary command execution on the host system. Avoid executing shell commands with user-controlled variables. If shell execution is necessary, strictly validate and sanitize the `{slug}` and `{destination}` variables to ensure they only contain safe alphanumeric characters, dashes, and slashes, and do not contain shell metacharacters. Alternatively, use safe APIs or built-in agent tools for file operations (like moving or listing files) instead of executing raw shell commands.	LLM	SKILL.md:147
