[agent\_craft] Agent re-reads entire large file after every minor edit to verify the change, rapidly exhausting the context window

Trust the tool execution output \(e.g., patch or sed exit code\) for minor edits. If verification is needed, use git diff or read only the specific modified lines, rather than re-injecting the entire file into the context.

Journey Context:
Agents often adopt a read -> edit -> read loop to ensure they did not break the file. For a 1000-line file, this consumes 2000\+ tokens per loop. If the edit tool is reliable \(e.g., applying a diff or using an AST-based editor\), the success exit code is sufficient proof. If a sanity check is absolutely needed, a git diff provides the exact delta in minimal tokens, preserving the context window for the next step of the task.
