Show HN: Badbox – A deterministic bad-pattern detector for codebases

Score: 6.5/10 (Innovation: 6, Technical: 7, Documentation: 8, Utility: 5)

Badbox is a deterministic (non-LLM) bad-pattern detector that lets teams encode project-specific anti-patterns as structural rules in a small DSL and checks codebases for them. It parses 30 languages, supports ownership grouping, containment, ordering relations, and baseline-based new-finding detection, making it a credible alternative to grep/AST scripts for custom lint policies. The project is well-documented and technically substantial, though it currently lacks default policies and has an experimental rule format.

Target audience: backend devs, devops, engineering teams enforcing custom code policies
