Unclear Which capability is added to the list is not stated.
What
When a session starts, Claude Code sends connected programs a message listing what it supports. That list can now include one more capability, added when an extra check passes. Before, the list came from two sources plus one condition.
The same step also reads a remote switch about automatic enabling for editors. It is off when the server sends nothing. The flag server has answered on for this site's account and for an anonymous baseline since a reading on 2026-10-07.
Why
Programs that drive Claude Code, such as code editors, may learn of one more thing Claude Code supports at the start of a session.

Feature flag
tengu_ide_rc_auto_enableOff by default, switched on for this account
The shipped code defaults this off, and the flag server returned on for the one account this site reads on this version. That is the reading that makes the entry above worth a second look, and it still says nothing about your account.

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.
