Builds a persistent SQLite graph of your codebase using Tree-sitter so Claude only reads what's actually affected by your changes. Instead of dumping entire projects into context, it maps structure once (10 seconds for 500 files), then updates incrementally on save. When you ask for a code review, Claude queries the graph for blast radius and pulls in just those files. The team claims 6.8x fewer tokens on reviews, up to 49x on daily tasks in large monorepos. Watch mode keeps it fresh as you code, and there's a Python API if you want to query callers, inheritance chains, or test coverage yourself. Honestly most useful if you're working in a big repo where context window waste is a real tax.
