Tldr Overview

When you land in an unfamiliar codebase, this gives you the lay of the land without burning through your context window. It chains together four TLDR commands: file tree filtered by extension, code structure showing functions and classes per file, a call graph to map how things connect, and complexity metrics on the entry points. You get a structured overview that costs a fraction of the tokens you'd spend dumping raw files. Skip it if you already know the project or you're debugging a specific function, but for that first day on a new repo, it beats grep and wishful thinking.
