Report #76388

[agent\_craft] Agent reads a large file into context, attempts a full rewrite, and drops or hallucinates unrelated sections of the file

Use search/replace or diff-based editing tools rather than full file rewrites. Only the modified lines need to be generated and injected into the file.

Journey Context:
Asking an LLM to rewrite a 500-line file to change 3 lines is a recipe for context-induced drift. The model will often subtly alter indentation, drop comments, or omit unchanged functions due to attention dilution over the long output. Diff-based tools constrain the generation to only the delta, preserving the rest of the file perfectly and saving output tokens.
