code-review-graph: Local Knowledge Graph Cuts Claude Code Token Usage by 49x on Large Repos

GitHub·high signal

code-review-graph (3.5K GitHub stars) builds a persistent AST-based knowledge graph of your codebase with Tree-sitter, then queries it at review time to compute the minimal context set Claude needs. On a 27,732-file Next.js monorepo, it reduces review context from 739K tokens to ~15K (49x reduction). Review quality scored 8.8 vs 7.2 on a ten-point scale compared to full-context reviews. Ships as a Claude Code plugin with incremental updates on git commits.
