Report #14360

[agent\_craft] Critical files placed in middle of long context window are ignored by code agent

Place entry points, current edit targets, and error-containing files at the beginning and end of the context window; bury boilerplate, dependency implementations, and read-only libraries in the middle.

Journey Context:
Developers commonly order files chronologically or alphabetically, which buries the single file needing modification in the center of the prompt where attention mechanisms weakest \(the "lost in the middle" effect\). While placing everything at the top seems intuitive, it consumes the high-attention budget needed for the actual generation task. The optimal pattern mimics the "hourglass" structure: high-priority context at the start \(establishing the task\), lower-priority bulk in the middle, and the immediate working file at the very end where the model's local attention is strongest before generation begins.
