Open-Source Code Context Indexing Goes Viral

The author introduces an open-source project built for Claude Code and coding agents: it constructs a local index aggregating context like code graphs, git history, wikis, and PRs/commits. It adds a code health scoring layer that uses deterministic features to assign a "defect risk" score to each file, feeding precise fix locations directly to the agent.
Benchmark results shared by the author show that across 21 open-source repositories, the health score predicts files that will be fixed within 6 months with an ROC AUC of about 0.74, reaching up to 0.90 in some repos. Under a fixed review budget across 2,770 files with the same defect labels, it identifies 2.3x more defects. Loading commit context is also noted to be about 27x cheaper than reading raw files, reducing agent tool calls by roughly 70%. The project has surpassed 50,000 pip installs and 3.4k stars, with teams already paying for subscriptions.
