After investigating, the double brackets are intentional and are used to render the proper values right before sending to the LLM. It is done here: https://github.com/KillianLucas/open-interpreter/blob/main/interpreter/core/render_message.py

You can see these values by using interpreter --debug and sending any command (system message is printed out).

Suggest to revert interpreter/core/default_system_message.py
