Show HN: I canceled my AI code reviewer and wrote a free local one

A developer created Avouch, a free, lightweight local Python code reviewer that analyzes only the files you're about to commit using Git, eliminating the need for paid AI code review services. The tool works offline with no daemon or network requirements, using Python's standard library to detect structural problems in changed code based on configurable rules in a TOML file. Avouch can be run before pushing commits and integrates with GitHub Actions and other CI systems.
