## Project history and usage

abi3audit is a Python packaging audit tool for finding violations and inconsistencies in Python abi3 extension modules and wheels. It can inspect local shared objects, wheels, PyPI packages, and package release histories.

### Project history

The README says abi3audit was created by Trail of Bits and is now maintained as part of the Python Packaging Authority. GitHub release metadata for early versions still references the trailofbits repository, while current PyPI metadata points to the PyPA source repository.

### Adoption history

abi3audit emerged from security and packaging concerns around Python's stable ABI. Its transfer to PyPA made it part of the Python packaging tool ecosystem, and the Homebrew input facts show it packaged as a command-line tool for macOS users.

### How it is used

Users run abi3audit against a shared object, a wheel file, or a PyPI package name. The README documents verbose output for mismatch details and a JSON report mode for tooling integration.

### Why package nerds care

abi3audit is package-nerd significant because abi3 wheels promise compatibility across CPython minor versions, but that promise is not automatically enforced at install time. The tool gives maintainers and distribution builders a way to check whether wheel tags and actual exported symbols agree.
