About Mellos Mapping

A live, terminal-native map of bottom-up development for Claude Code, ChatGPT desktop Codex mode and Codex CLI. While Claude builds your system, a split pane beside the conversation shows the system's layered dependency map: primitive layers at the bottom, dependency edges that may only point downward, ghost nodes for what is designed, a spinner on what is being built right now, and solid green for what is built and verified.
