CLI Tool Turns Git History Into Searchable Failure Pattern Database
A developer has released hermes-harness, an open-source command-line tool that mines git histories to identify and index recurring failure and fix patterns across multiple repositories. The tool extracts signals such as reverts, file co-changes, and topic clusters, compressing each pattern into a 128-dimensional vector for fast cosine similarity search. It is designed for tech leads and platform engineers managing three or more repositories who struggle to recall how past bugs were resolved. No AI is used at query time, making searches fast and self-contained. The project is available via npm and accepts contributions on GitHub.
