Improve Codebase Architecture

Surface architectural friction as deepening opportunities: refactors that turn shallow modules into deep ones. Use the codebase-design vocabulary throughout and respect the active project's domain language and ADRs.

Resolve every .agents/projects/ path from the repository root; never read or write project artifacts in a global agent-installation directory.

Process

1. Scope before scanning. Use a direction named by the user, or inspect a useful span of commit history to identify recently changing hot spots. Read .agents/projects/<project>/CONTEXT.md and relevant project ADRs, then explore the selected area for shallow modules, leaking seams, poor locality, and interfaces that resist behavior-focused tests. Apply the deletion test to every candidate.

   Done when candidates are grounded in real friction in the selected code area.
