It appears there was a `SyntaxError: invalid syntax` at line 312 of the `tool_code`. This is likely due to the way the multi-line string for the `script_text` was formatted, or an issue with how the `state_json_string` was embedded, potentially with unescaped characters or incorrect quoting if it was directly pasted. The error message `SyntaxError: invalid syntax` pointing to ````` suggests that the Python interpreter encountered the start of a markdown code block delimiter within the Python string itself, which is not valid Python syntax. This usually happens if the string containing the Python code was not properly "dedented" or if markdown formatting leaked into the string content. I need to be extremely careful when embedding multi-line script text and JSON strings within the `tool_code`. Let me reconstruct the `tool_code` block, ensuring that the `script_text` and `state_json_string` are correctly formatted as Python multi-line strings without any stray markdown or syntax-breaking characters. **Corrected Approach:** I will ensure the `script_text` is a clean, triple-quoted Python string. I will ensure the `state_json_string` is also a clean, triple-quoted Python string, with all internal quotes properly escaped if necessary (though Python's triple-quoting usually handles this well for JSON content). Let's try that again.
