Autogenerated summaries of each of the compiler passes which allow agents to get the key ideas of a compiler pass, including key input/output invariants, without having to reprocess the file each time. In the subsequent diff this seemed to help.
React Compiler
React Compiler is a compiler that optimizes React applications, ensuring that only the minimal parts of components and hooks will re-render when state changes. The compiler also validates that components and hooks follow the Rules of React.
More information about the design and architecture of the compiler are covered in the Design Goals.
More information about developing the compiler itself is covered in the Development Guide.
