Score: 6.8/10 (Innovation: 5, Technical: 7, Documentation: 8, Utility: 7)

pii-hound is a CLI tool for detecting Personally Identifiable Information and developer secrets across databases, cloud storage, and files. It's interesting because it combines heuristic column matching with regex validation (like Luhn for credit cards) and uses efficient algorithms like Aho-Corasick and reservoir sampling for performance.

Target audience: devops, data engineers, backend devs
