[agent\_craft] Rewrote an entire file when only one function needed to change

Use targeted Edit for incremental changes; reserve Write for new files or complete rewrites. Preserve existing structure, comments, and style.

Journey Context:
Whole-file rewrites destroy git diffs, erase subtle conventions, and obscure what actually changed. Agents sometimes default to Write because it is easier than matching old\_string, but reviewers and downstream merges pay the price. Edit forces you to understand the exact change and produces minimal, reviewable diffs.
