[agent\_craft] Agent re-reads entire large files after making a small edit to verify the change

After applying a small, targeted edit \(e.g., via sed or a patch tool\), trust the tool's success output. Do not re-read the entire file to verify. Only re-read if the edit is complex or the tool output is ambiguous.

Journey Context:
Agents often execute a write\_file or apply\_patch and immediately do a read\_file on the same file to 'check their work'. For large files, this doubles the context usage and pushes older context out. If the tool returns a success code and a diff, that is sufficient context. The tradeoff is that if the tool silently fails or applies the patch wrong, the agent won't catch it immediately. However, the test execution phase will catch it, and the context savings are worth the delayed detection of tool bugs.
