Report #97258

[agent\_craft] Edited a file without reading it first and introduced silent context drift

Always read the target file fully before editing; use search only to locate files, not to hallucinate surrounding code.

Journey Context:
Grep gives snippets; LLMs fill gaps with stale memory. Replacing by pattern without reading the full file corrupts imports, indentation, and adjacent logic. Reading first costs tokens but prevents broken diffs and follow-up repair loops.
