Report #16763

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

Use search/replace block tools or AST-based patching to apply surgical diffs rather than outputting the entire file content.

Journey Context:
Early agents used write\_file which required outputting the whole file. This is extremely token-heavy for a 1000-line file where only 2 lines change, and the LLM often introduces accidental deletions or hallucinations in unchanged sections. Diff-based tools keep the context focused on the delta, saving tokens and reducing error rates.
