Report #101528

[tooling] Running a one-off Python script drags in global package conflicts or takes too long to set up

Use \`uv run --python 3.12 --with requests,rich script.py\`. \`uv\` downloads the requested Python version and dependencies into an ephemeral environment, runs the script, and cleans up. For repeated use, add an inline script metadata block at the top of the file: \\\# /// script \\\# dependencies = \["requests>=2.32", "rich"\] \\\# requires-python = ">=3.10" \\\# /// Then \`uv run script.py\` is enough.

Journey Context:
\`pip install\` into the system or user environment creates conflicts and makes scripts non-reproducible. \`venv\` is better but still requires manual creation and activation. \`uv run\` is the fastest path to a hermetic, throwaway Python runtime with pinned dependencies. The inline metadata format \(PEP 723\) lets a single \`.py\` file declare its own dependencies, turning it into a self-contained executable artifact. Agents often skip this because it looks like project setup overhead, but it is literally one command.
