title: Package-metadata validation — <code>twine check</code> + friends
---
Before every publish, <code>twine check</code> confirms the long
           description renders on PyPI, <code>check-wheel-contents</code> catches
           stray or missing files, and <code>pyroma</code> scores the metadata
           completeness. Stops a broken PyPI page or an empty wheel from reaching
           users — the release path currently trusts the build blindly.
