Configure pyproject.toml for scientific Python packaging by defining PEP 621 metadata, including project name, version, license declarations, classifiers, and dependencies. This Skill guides you through structuring modern packaging standards and optional dependency groups for reproducible builds.

The src-layout isolates package source code from test files to prevent path conflicts during testing and ensure reliable builds. Using a src/ directory guarantees that imports resolve from the installed package rather than the local directory.

Build and publish a Python package to PyPI by integrating the Hatchling build system in your pyproject.toml, executing the build process, and uploading the resulting distributions. This Skill provides workflows and templates for standard PyPI publishing.

You can manage optional dependencies in pyproject.toml by defining extras groups within the PEP 621 metadata. This Skill covers configuring optional dependency groups to separate core requirements from testing or documentation tools.

This packaging workflow directly supports scientific Python community guidelines by standardizing pyproject.toml metadata, src-layout adoption, and reproducible build configurations tailored for scientific projects.
