Report #101043

[tooling] Python scripts fail because of missing dependencies or wrong interpreter

Use \`uv run --python 3.12 script.py\` or add an inline script metadata header \(\`/// script\`\) so uv resolves dependencies automatically without polluting the global environment.

Journey Context:
pip installs create permanent global or per-project environments that drift. uv can create ephemeral, on-demand environments and run scripts with declared dependencies in seconds. The inline metadata format \(\`\# /// script\`, \`\# dependencies = \[...\]\`, \`\# ///\`\) lets a single \`.py\` file carry its own requirements, making one-off automation scripts reproducible. The trap is assuming \`uv run\` mutates a venv like \`pip install\`; it often builds a temporary environment unless you explicitly sync a \`pyproject.toml\` or use \`uv pip install\`. For agents doing quick automation, prefer \`uv run\` over manual venv management.
