Instructions

When this skill is invoked, follow this flow:

Python Runtime (Required)

Before running any shell snippet below, define this resolver in the same shell. It accepts only Python 3.12 or newer, prefers python3 and then python, and uses uv as the final fallback. Call ouroboros_python directly and quote every argument passed to it; the function preserves arguments and heredoc/stdin input. Only the probe and child interpreter discard inherited CPython path-selection overrides; the caller shell keeps its environment unchanged.

ouroboros_python() {
  if command -v python3 >/dev/null 2>&1 &&
    (unset PYTHONHOME PYTHONPATH PYTHONPLATLIBDIR PYTHONEXECUTABLE __PYVENV_LAUNCHER__; command python3 -c 'import sys; raise SystemExit(sys.version_info < (3, 12))') >/dev/null 2>&1
  then
    (unset PYTHONHOME PYTHONPATH PYTHONPLATLIBDIR PYTHONEXECUTABLE __PYVENV_LAUNCHER__; command python3 "$@")
    return
  fi
  if command -v python >/dev/null 2>&1 &&
    (unset PYTHONHOME PYTHONPATH PYTHONPLATLIBDIR PYTHONEXECUTABLE __PYVENV_LAUNCHER__; command python -c 'import sys; raise SystemExit(sys.version_info < (3, 12))') >/dev/null 2>&1
  then
    (unset PYTHONHOME PYTHONPATH PYTHONPLATLIBDIR PYTHONEXECUTABLE __PYVENV_LAUNCHER__; command python "$@")
    return
  fi
  if command -v uv >/dev/null 2>&1; then
    (unset PYTHONHOME PYTHONPATH PYTHONPLATLIBDIR PYTHONEXECUTABLE __PYVENV_LAUNCHER__; command uv run --no-project --quiet --python '>=3.12' python "$@")
    return
  fi
  printf '%s\n' 'Ouroboros skills require Python >= 3.12 or uv on PATH.' >&2
  return 127
