[gotcha] Shell command injection through unsanitized tool parameters

Avoid shell execution tools \(like \`bash\` or \`exec\`\) whenever possible; if required, use parameterized execution \(execvp style\) instead of string concatenation, and strictly validate/sanitize inputs.

Journey Context:
Agents are often given a 'run bash command' tool. If the LLM constructs the command string from user input \(e.g., \`git commit -m "user input"\`\), an attacker can inject shell escapes. Parameterized execution prevents shell interpretation, but developers often default to string concatenation because it's easier to implement.
