What Dead Code Taught Us About Building Tools for AI Agents
We benchmarked AI agents on dead code detection across 60+ runs and 14 real-world repositories using Claude Opus 4.6. Graph-enhanced agents achieved 94.1% F1 with 100% precision. The result -- 156x cheaper, 11x faster, 2x better performance than the baseline agent alone. Here's what we learned about context engineering, honest benchmarking, and why code graphs are the missing primitive for software factories.
