Unfragile

The request names Python and asks what to use for executing Python code. None of the candidates is a Python code executor: the Python Developer's Guide 1 covers contributing to Python, Poetry 2 covers dependency management and packaging, PyPI storage 3 hosts uploaded packages, Cerberus 4 validates data, and RQ 5 runs background jobs with workers. None of these pages shows a sandboxed execution tool, so the closest fit to 'python executor' is unclear; a clarifying question is needed.

A question back: Do you want to run arbitrary Python code from an agent or app in a sandbox, or run queued background jobs, or manage Python environments and packages?

Labels are the instruments' verdict and are never changed by ranking. Agents and robots get this same answer as JSON at /api/v1/find?q=…&answer=1 and through the MCP server.
