User: 

You are given access to make searches on the Internet. The format for making a search is: 1. The user sends a message. 2. You will decide whether to make a search. If you choose to make a search, you will output a single message, containing the word 
 (EXACTLY AS IT IS GIVEN TO YOU), followed by ONLY your web search query. After outputting your search query, you MUST output the token 
 (EXACTLY AS IT IS GIVEN TO YOU) to denote the end of the search query. Keep your search query concise as there is a 400 characters limit.
The system will then append the web search results at the end of the user message, starting with the token 
. Take note that the user CANNOT ACCESS the content under 
 - YOU should incorporate these results into your response. Additionally, If the token 
 is present in the user's message, then you MUST NOT request another web search.

IMPORTANT! You should choose to search the web ONLY if ANY of the following circumstances are met:
1. User is asking about current events or something that requires real-time information (news, sports scores, 'latest' information, etc.)
2. User is asking about some term you are unfamiliar with (e.g. if it's a little-known term, if it's a person you don't know well, etc.)
3. User is asking about anything that involves numerical facts (e.g. distances between places, population count, sizes, date and time, etc.)
4. User explicitly asks you to search or provide links to references.
If the user's query does NOT require a web search, YOU MUST NEVER run one for no reason.
However, NEVER refuse to search the web if the user asks you to provide such information.

When using web search results, you are encouraged to cite references where appropriate, using inline links in standard markdown format.
You are also allowed to make use of web search results from previous messages, if they are STRONGLY RELEVANT to the current message.

When you are not running a web search, respond completely as per normal - there is NO NEED to mention that you're not searching. 
Do your best to be informative. However, you MUST NOT make up any information. If you think you might not know something, search for it.

Assistant: Understood. I will strictly follow these instructions in this conversation.
User: I have a struct and I want to add a new field to it: "forced_working_days". How I can add it without changing actual code?

WorkingDayUpdate = Struct.new(:working_days, :non_working_days, keyword_init: true)
Assistant: If you're looking to add a new field to a Ruby `Struct` without altering its original declaration, unfortunately, this isn't directly possible. A `Struct` in Ruby has a fixed number of members that are set when it's defined, and you can't dynamically add new members or fields to an existing `Struct` type.

However, there are alternative approaches you can consider:

1. **Subclass the Struct**: You can create a new subclass of the `Struct` and add additional fields. This maintains the original struct while allowing you to work with an extended version.

    ```ruby
    class ExtendedWorkingDayUpdate < WorkingDayUpdate
        def initialize(forced_working_days: nil, **args)
          super(**args)
          @forced_working_days = forced_working_days
        end
      
        attr_accessor :forced_working_days
    end

    working_day_update = ExtendedWorkingDayUpdate.new(
      working_days: ["Monday", "Tuesday"],
      non_working_days: ["Saturday", "Sunday"],
      forced_working_days: ["Friday"]
    )
  
    puts working_day_update.forced_working_days
    ```

2. **Use a Hash Instead**: If flexibility is a priority, consider using a Hash instead of a Struct. Hashes are more dynamic and can have fields added as needed.

    ```ruby
    working_day_update = {
      working_days: ["Monday", "Tuesday"],
      non_working_days: ["Saturday", "Sunday"],
      forced_working_days: ["Friday"]
    }

    puts working_day_update[:forced_working_days]
    ```

3. **Use OpenStruct**: If you require more fluid struct-like objects, consider using `OpenStruct`, which allows dynamic addition of attributes.

    ```ruby
    require 'ostruct'

    working_day_update = OpenStruct.new(
      working_days: ["Monday", "Tuesday"],
      non_working_days: ["Saturday", "Sunday"]
    )

    working_day_update.forced_working_days = ["Friday"]

    puts working_day_update.forced_working_days
    ```

Choose the approach that best suits your requirements, considering whether you need the strictness of a Struct or the flexibility of an open-ended data structure like a Hash or OpenStruct.
User: Can I include an ActiveSupport::Concern to WorkingDayUpdate to extend it?
