Function WritePlanLimitError

internal/cli/client.go:1256–1268

WritePlanLimitError formats a plan-limit rejection to w in the canonical two-track shape (TASK-788): 1. A single `pad-structured-error/v1: {json}\n` marker line — consumed by the MCP stdio classifier so it lifts the structured payload instead of falling through to a generic server_error. 2. A human

(w io.Writer, apiErr *APIError)

// This mirrors WriteOpenChildrenError exactly in structure so the two paths
// are easy to reason about together.
func WritePlanLimitError(w io.Writer, apiErr *APIError) {
	envelope := map[string]any{
		"error": map[string]any{
			"code":    apiErr.Code,
			"message": apiErr.Message,
			"details": apiErr.Details,
		},
	}
	if data, err := json.Marshal(envelope); err == nil {
		fmt.Fprintln(w, StructuredErrorMarker+string(data))
	}
	fmt.Fprintln(w, apiErr.Message)
}
