Coding agents stop unzipping JARs: Netflix wires JetBrains' code engine into Claude Code and Codex, cutting tokens and time by 20–30%
Netflix ran JetBrains' code-indexing engine, the one behind IntelliJ IDEA, headlessly inside Claude Code and Codex so coding agents can query Java/Kotlin symbols and library structure instead of unzipping JARs, decompiling and grepping. On two real codebases, with the same model and task, enabling the engine typically cut token use and completion time by 20–30%, up to about 65% in the best configuration, without lowering correctness.
