"Unhandled node type: string" prompt interrupts workflow

Description

When using Claude Code CLI (v2.1.112), a prompt frequently appears:

Unhandled node type: string

Do you want to proceed?
❯ 1. Yes
  2. No

This interrupts the workflow and requires manual confirmation. It appears when processing certain tool results or MCP responses that contain unexpected node types.

Expected Behavior

Either handle the node type silently, or provide a configuration option to auto-proceed (similar to how other confirmations can be configured).

Environment

• Claude Code version: 2.1.112
• Platform: Linux (WSL2 on Windows)
• Shell: bash
• MCP servers in use: Atlassian

Reproduction

Occurs intermittently during normal tool use, particularly when MCP tool results contain certain data structures.

Suggestion

Add a config option like "autoHandleUnknownNodeTypes": true in settings, or handle string node types gracefully without prompting.
