Report #13379

[agent\_craft] Agent rewrites entire large files to make small changes, wasting context tokens and risking regression

Use search/replace blocks or diff-based editing tools for modifications. Only rewrite entire files if they are small or structurally completely changed.

Journey Context:
Generating the full content of a 500-line file to change 2 lines consumes massive output tokens and increases the probability of hallucinating or dropping unrelated code. Diff-based editing constrains the output to only the changed lines, saving tokens, reducing latency, and preserving the untouched code exactly.
