Report #73592

[agent\_craft] Agent re-reads entire large files into context to verify small changes, wasting tokens and increasing drift

Use git diff or line-number-based reading strategies instead of reading whole files. After writing code, verify the changes by reading only the modified lines or the diff output, not the entire file.

Journey Context:
When an agent edits a 1000-line file, it often reads the whole file again to verify the edit worked. This is extremely token-inefficient. The agent already has the pre-edit state in its context. Reading the diff provides a highly compressed, high-signal verification step. It confirms exactly what changed without reloading the 990 lines that stayed the same, preventing context rot.
