When a panel member spawned a subagent via the Agent tool, the Claude CLI emitted the subagent's internal steps as separate top-level messages carrying parent_tool_use_id: tool_use blocks arrived as type:"assistant" (no handler → dropped) and the matching tool_result as type:"user", which created a nameless, label-less collapsible box in the frontend — both in the live stream and in the persisted history (same segment source). Skip any top-level event with a non-empty parent_tool_use_id at the single stream JSON parser, so subagent internals never become CliStreamEvents. This covers worker and panel-member paths at once. The Agent tool call itself (parent_tool_use_id=null) stays visible, and the final result event — which aggregates subagent tokens — carries no parent_tool_use_id, so the token balance is unaffected.
