// NewToolResultAwaitingFormSubmission signals to the agent that a tool call

// has been intercepted to show an MCP App form to the user and has NOT

// performed the requested operation. The agent must stop, not chain dependent

// tool calls, and not claim the operation succeeded. The result is marked

// IsError=true so agents that bail on error don't proceed; the host still

// renders the UI because rendering is keyed off the tool's _meta.ui, not the

// result. The MCP App form will submit the operation directly when the user

// clicks submit, after which a ui/update-model-context call delivers the real

// outcome to the agent.
