Unclear Nothing has been read yet about whether the tengu_bridge_child_tool_diff setting is switched on for any account.
What
In a Remote Control ("bridge") session, Claude Code now defaults to computing a diff for tool calls like Write and Edit, so the change can be reported back over the bridge. This is controlled by the tengu_bridge_child_tool_diff setting, which is checked only when the session's environment is a bridge session (CLAUDE_CODE_ENVIRONMENT_KIND === "bridge"). Setting CLAUDE_CODE_REMOTE always forces this on regardless of that flag.
Why
Showing a diff for file-changing tool calls lets the Remote Control host display exactly what changed, without extra configuration.
Nothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.
