Report #38983

[agent\_craft] Flat file content without structural context causes agents to edit wrong files or create files in wrong directories

Inject condensed directory tree \(e.g., tree command output\) at context start, followed by files marked with explicit path headers like \#\#\# FILE: path/to/file

Journey Context:
Agents often receive files as a flat concatenation of contents without the 'map' of the repository. This leads to errors like editing src/utils.js when the target was lib/utils.js, or not knowing where to create a new test file. The tree view provides the structural context \(which directories exist\), while explicit file headers prevent delimiter collision and clearly demarcate file boundaries. This is essential for multi-file coding agents.
