Cognition Labs launched a Code Graph Indexer for its autonomous engineer Devin. By maintaining incremental AST dependency topologies across repositories, Devin reduces symbol and call-chain retrieval times in 1M+ line monorepos from 8s to under 600ms, while cutting irrelevant context token overhead by 65%.

Key Takeaways

  • βœ“Incremental AST and dependency graph topology drastically speeds up agent comprehension in huge repos.
  • βœ“Symbol retrieval in million-line monorepos drops to 600ms with a 65% token saving.
  • βœ“Live for all Devin Enterprise users with support for self-hosted code repositories.
