Execute complex Python code via run_shell heredoc when execute_code_sandbox fails
安装前可以查看交给 AI 代理的指令内容。
When execute_code_sandbox fails repeatedly (e.g., with "unknown error"), use run_shell with a Python heredoc as a reliable fallback for executing multi-line Python scripts with imports.

command="""python3 << 'EOF'
import sys
# Your Python code here
print("Hello from heredoc")
EOF""",
timeout=300
)
<< 'EOF' (with single quotes) to prevent shell variable expansionEOF on its own line (no leading whitespace)run_shell(

c.drawString(100, 750, "Hello PDF")
c.save()
print("PDF created successfully")

import pandas as pd
import json
# Load and process data
df = pd.read_csv("data.csv")
summary = df.describe()
# Output results
print(summary.to_string())
with open("summary.json", "w") as f:
json.dump(summary.to_dict(), f)
print("Processing complete")

)
| Issue | Solution |
|---|---|
EOF not recognized | Ensure EOF is on its own line with no leading spaces |
| Import errors | Verify packages are installed in the shell environment |
| File not found | Use absolute paths or check working directory with pwd |
| Syntax errors | Check Python indentation within heredoc |

When Python execution repeatedly fails in execute_code_sandbox, use a file-based alternative: save the script, run it through the shell, and capture results or errors. The guidance covers paths, imports, timeouts, structured output, and optional cleanup.
