What probably matters to youSection of the release

The SendFile tool now sits behind a server flag that falls back to off, so it can be enabled remotely.

What

The tool for sending files to another Claude Code session was previously disabled unconditionally. It is now behind the server flag tengu_send_file, which falls back to off when the server sends no value, so the tool can be switched on remotely without a new build.

Feature flag
tengu_send_file Not enough to say

Nothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.
