Merged
Conversation
The Write tool previously failed when a parent directory was missing, forcing a manual mkdir round trip. It now creates missing parents recursively before writing.

Problem
The
Writetool failed with a "parent directory does not exist" error whenever it was asked to write into a not-yet-created subfolder. In practice the agent would then runmkdirand retry the same write, adding a redundant round trip for a very common case.What changed
Writenow creates missing parent directories recursively (likemkdir(parents=True, exist_ok=True)) before writing, so writing into a fresh subfolder succeeds in one call. An existing parent path that is not a directory is still a hard error, and the change is covered by updated tests. The tool description and the en/zh reference docs are updated to match.Checklist
