Sandbox Execution Fallback
When to Use
Use this skill when
execute_code_sandbox fails during Python code execution, particularly for tasks involving:
- Spreadsheet generation (xlsx, csv)
- Data processing and transformations
- File output operations
- Complex computations requiring libraries
Recovery Pattern
When
execute_code_sandbox returns an error or fails to produce expected output:
Step 1: Write Python Code to File
Use
write_file to save your Python script to a file:
# Use write_file tool with: path: "script.py" content: <your complete Python code as a string>
Step 2: Execute via Shell
Use
run_shell to execute the script:
# Use run_shell tool with: command: "python3 script.py" timeout: <appropriate timeout, e.g., 300 for long-running tasks>
Step 3: Verify Output
Check the shell output for:
- Success messages or printed results
- Error messages (if any, diagnose and fix the script)
- File creation confirmations
Step 4: Access Generated Files
If the script creates output files (e.g., spreadsheets), they will be in the current working directory. Use
list_dir to confirm, then read_file to access if needed.
Why This Works
- Same Python Environment:
in the shell uses the same environment as the sandboxpython3 - More Robust: Shell execution handles long-running or memory-intensive tasks better
- Debuggable: Errors are captured in stdout/stderr for easier diagnosis
- Identical Results: Produces the same output as sandbox execution when successful
Example: Spreadsheet Generation
Original code that failed in execute_code_sandbox:
import pandas as pd data = {'A': [1, 2, 3], 'B': [4, 5, 6]} df = pd.DataFrame(data) df.to_excel('output.xlsx', index=False) print("File created successfully")
Recovery Execution:
with path="generate_spreadsheet.py" and the code above as contentwrite_file
with command="python3 generate_spreadsheet.py"run_shell- Verify output.xlsx was created with
list_dir
Tips
- Increase
for complex operations (default 30s may be insufficient)timeout - Add explicit print statements for debugging
- Handle exceptions in your script and print error messages
- Clean up temporary script files after successful execution if needed
