[agent\_craft] Agent re-reads entire large files after making a small edit, wasting tokens and slowing down the loop

After applying a code edit, update the agent's internal context model using a diff/patch representation rather than re-reading the full file. Only force a full re-read if an external linter or compiler throws an error.

Journey Context:
Many agent frameworks naively read the file, write to it, and then read it again to verify the state. For large files, this burns massive tokens. If the agent authored the edit, it already knows the intended state. Applying a diff locally to the context string saves the read-back tokens. Only fall back to a full re-read if an external tool indicates the internal context model is out of sync with reality.
