This restructures how AI agents understand the repository, moving from a single overloaded instruction manual to localized context files. Tools like Claude Code now receive highly specific rules based on the exact directory they modify, reducing architectural drift and unsafe database operations.
The massive root instructions file has been sliced into a series of targeted context files placed directly inside applications, packages, and internal modules. Alongside this decentralization, a new evaluates incoming pull requests. It automatically flags when structural changes require documentation updates to prevent context rot.
Global directives, such as public package constraints or , are isolated in a dedicated rules directory. Localized architecture details, like the distinction between legacy and modern run engines, live strictly where the code executes.
