What it does
Fallback Python Execution is an agent skill from HKUDS/OpenSpace. Reliable Python execution workflow when executecodesandbox or shellagent fail
Its SKILL.md is about 680 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file.
It sits in Documents & Office. It works with Python. The repository describes itself as: "OpenSpace: The Skill Management Layer for AI Agents" -- https://open-space.cloud/. The licence is MIT.
When your agent uses it
- Documents & Office work in your project
Example prompts
- “/fallback-python-execution”
Requirements
- Python 3
Workflow steps
3 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 3827781. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
python
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Fallback Python Execution loads about 676 tokens when it runs. Until then it costs about 27 tokens; SKILL.md has 257 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
The full file from HKUDS/OpenSpace at commit 3827781, republished under its MIT licence (© HKUDS). 257 words, ~676 tokens.

Fallback Python Execution Pattern
When to Use
Use this pattern when:
execute_code_sandboxreturns unknown errors or fails repeatedlyshell_agentcannot successfully execute Python code- You need to create files (spreadsheets, documents, data files) via Python
- Direct delegated approaches prove unreliable in the current environment
Core Technique
Instead of delegating Python execution to agents, use this two-step inline approach:
- Write Python code to a
.pyfile usingwrite_file - Execute the file using
run_shellwithpython <script.py>
Step-by-Step Instructions
Step 1: Write Python Code to File
Use write_file to create a Python script with all necessary code inline:
write_file
path: /path/to/script.py
content: |
import pandas as pd
# Your complete Python code here
df = pd.DataFrame({...})
df.to_excel('output.xlsx', index=False)Step 2: Execute via run_shell
Run the script directly:
run_shell
command: python /path/to/script.pyStep 3: Verify and Clean Up
- Check the output for success/errors
- Verify the expected files were created
- Optionally remove the temporary script if no longer needed
Why This Works
This approach is more reliable because:
- Avoids agent interpretation layers that can introduce errors
- Provides direct control over execution environment
- Gives clear error output for debugging
- Bypasses sandbox delegation issues
Example: Excel File Creation
# Step 1: Write the script
write_file:
path: create_report.py
content: |
import pandas as pd
from openpyxl import Workbook
# Create data
data = {'Column1': [1, 2, 3], 'Column2': ['A', 'B', 'C']}
df = pd.DataFrame(data)
# Save to Excel
df.to_excel('report.xlsx', index=False)
print('Excel file created successfully')
# Step 2: Execute
run_shell:
command: python create_report.pyTips
- Include error handling in your Python code for better debugging
- Use absolute paths when possible to avoid working directory issues
- Add print statements to track execution progress
- Keep scripts self-contained with all imports at the top
- For complex tasks, break into multiple scripts if needed
Troubleshooting
| Issue | Solution |
|---|---|
| Module not found | Add pip install commands before python command |
| Permission errors | Check file paths are writable |
| Script not found | Use absolute path or cd to directory first |
| Output not created | Check for Python errors in run_shell output |
