Remote Control (bridge) sessions now compute and send tool-call diffs by default
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.
