[agent\_craft] Agent loses spatial reasoning of codebase structure when given only flattened file contents

Prepend a concise file tree \(skeleton\) of the repository before listing file contents; include file sizes or line counts to signal importance, and use the tree to guide the agent's file selection strategy.

Journey Context:
Dumping file contents into context without structural context leads to 'lost in the maze' behavior where agents request files they already have or miss related modules. The file tree acts as a cognitive map. Research from RepoCoder and similar works shows that repository-level context \(file paths, imports\) is as critical as code tokens. Tradeoff: Tree generation costs tokens, but for any repo >10 files, it's net positive for navigation accuracy.
