Report #66061

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

Use search-and-replace or diff-based editing tools instead of full-file rewrite tools for files over ~50 lines. Only load the specific lines to be changed into the context, and output a targeted patch.

Journey Context:
When an agent reads a 500-line file, keeps it in context, and rewrites the whole thing, it often introduces accidental whitespace changes, drops comments, or exceeds output token limits. Diff-based tools force the agent to focus only on the relevant lines, saving context tokens in both input and output, and reducing the surface area for errors.
