Important — Spawn a sub-agent to perform this review. Pass it only these instructions and the target files. The review is most effective when the agent starts with a clean context window.

Scope

If the user specified files or directories, pass those to the sub-agent. If not, ask what they'd like you to review before proceeding.

Goal

Make this code trivially easy to pick up cold. Someone opening this file in six months should understand what it does in seconds. All changes should preserve the original functionality and behavior.
