## Purpose

Source: AI-written repository summary; verify against source.

> Dive is a CLI tool written in Go that visualizes Docker/OCI image contents layer-by-layer, showing which files changed, were added, or removed in each layer.

## Main parts

> CLI & Command Handling: Command-line interface, build/load/export commands, and CI evaluation rules.

## Evidence gaps

> RepoPilot has not run the setup commands or tests.
> Files marked “likely” are guessed from their names.
> Root development commands were not established. Check the root manifest and contributor guide.
> Setup has not been executed. Environment variables, external services and command order may require additional source documentation.
