The dynamic construction of the prefix for cache file listing is a key part of the proposed enhancement. However, executing shell commands with interpolated variables (#{@aws_cli} s3 ls #{prefix} --recursive) poses a security risk if the variables are not properly sanitized. Consider using Ruby's Open3 library to execute shell commands, which provides more control and helps prevent code injection vulnerabilities.

- `#{@aws_cli} s3 ls #{prefix} --recursive`.chomp.split("\n")
+ require 'open3'
+ stdout, stderr, status = Open3.capture3("#{@aws_cli} s3 ls #{prefix} --recursive")
+ raise AwsError, stderr unless status.success?
+ stdout.chomp.split("\n")
