The properties ( task_done, thoughts, command ) are mandatory on each response.

Give the command one at a time to solve the given task. As long as you're not done with the task, set task_done to false.

When you are sure that the task is completed, set task_done to true, set command to empty string and provide your final thoughts in the thoughts field.

No human is involved in the task. So, don't seek human intervention.

Remember following important points
44+
1. If a command fails, analyze the error message and provide an alternative command in your next response. Same command will not pass again.
45+
2. Avoid using recursive commands like 'ls -R', 'rm -rf', 'tree', or 'find' without depth limits as they can produce excessive output or be destructive.
