Report #1604

[agent\_craft] Agent holds stale file contents in context after writing changes, leading to edits based on outdated code or duplicate modifications

After a file write/update tool call, explicitly evict the old file content from the context window or mark it as stale. If further edits are needed, re-read the file to guarantee the context reflects the current disk state.

Journey Context:
When an agent reads a file, it stores it in context. If it then writes to that file, the original read is still in the history. If the agent needs to make another edit, it might reference the old version. Simply re-reading the file after every write costs tokens but guarantees freshness, preventing cascading syntax errors from applying diffs to an outdated mental model.
