Show HN: Wy, a Rust Terminal Tool for Understanding AI-Generated Code

Summary

Wy is an open-source terminal tool written in Rust for helping engineers understand code produced by AI agents. It addresses a gap between a Git diff, which shows what changed, and the context behind those changes, which can disappear during long-running agent sessions. The project is aimed particularly at unfamiliar codebases where agents are a primary interface for development. Its terminal UI lets users browse code changes together with relevant agent notes, request explanations or follow-up questions and changes, open code references and citations, and distinguish the justifications recorded by agents. Wy is presented as a companion to agent-based development, intended to help engineers build better judgment about the resulting code.
