sync_files has its own transport, deadline and a "sync working copy" display.
What
Remote hosts gain a third tool category next to served and passthrough tools, currently containing exactly one entry, sync_files, with its own transport call carrying its own deadline, cancellation and timeout. Results can carry a directory-sync field that becomes a session note, and the tool-use display learns a sync action shown as "sync working copy".
Details
- The new call path rejects anything not in the fixed one-item set.
- The directory-sync field is read from either the structured result content or the result metadata.
Evidence
callPlumbing: not a plumbing tool
