tool listing is static

I set TOOLS_DIR to an empty "no-tools" directory, thinking that this would disable tool usage, but to my surprise, Claude continued to use the (now non-existent) tools. I tracked this down to the fact that claude-engineer is told about its tools in a static system prompt:

prompts/system_prompts.py

    TOOL_USAGE = """
...
    7. Available tools and their use cases
       - BrowserTool: Opens URLs in system's default browser
       - CreateFoldersTool: Creates new folders and nested directories
       - DiffEditorTool: Performs precise text replacements in files

ce3.py

                system=f"{SystemPrompts.DEFAULT}\n\n{SystemPrompts.TOOL_USAGE}"

I think the system would be better off with a singular "list-tools" tool installed, statically, along with some guidance when to use it.
