Report #94111

[agent\_craft] Token limit exceeded when resending full file context every turn in long sessions

Send full file only on first turn; subsequent turns send only diff \(line changes\) plus outline of unchanged regions.

Journey Context:
Full file resend is O\(n\) per turn, quickly exhausting context limits for files >500 lines. Diff-based context reduces subsequent turns to O\(changes\). The model maintains state of the full file from turn 1; sending diffs leverages this statefulness while preserving context window. Include line numbers in diffs to help the model map changes to the original outline.
