Stronger AI Coding Agents Burn More Tokens: How roam-code's Code Graph Cuts Costs 63%

roam-code builds a local SQLite code graph using tree-sitter for 28 languages, letting AI agents query precise call relationships instead of grep or RAG, reducing agent turns by 83%, tokens by 80%, and cost by 63% in experiments, while adding deterministic pre-edit context injection and post-edit verification gates.
