Doubt about very little improvement in L7 - Step2 in process_user_answer

In step 2 of process_user_message function:

 # Step 2: Extract the list of products
    step_2_system_message = utils.step_2_system_message
    step_2_messages =[step_2_system_message] + all_messages
    step_2_messages = step_2_messages + [    
        {'role':'user', 'content': f"{delimiter}{user_input}{delimiter}"},  
    step_2_response = get_completion_from_messages(step_2_messages)

The part of step_2_system_message is always called, so everytime you call the process_user_answer function ( which is every time a new user input is generated), you have to load the list of products and categories and add this turn in the all_messages list…So all_messages could have a lot of repeated entries:

step_2_system_message_content = f"""
You will be provided with customer service a conversation. \
The most recent user query will be delimited with \
{delimiter} characters.
Output a python list of objects, where each object has \
the following format:
    'category': <one of Computers and Laptops, \
    Smartphones and Accessories, \
    Televisions and Home Theater Systems, \
    Gaming Consoles and Accessories, 
    Audio Equipment, Cameras and Camcorders>,
    'products': <a list of products that must \
    be found in the allowed products below>

Where the categories and products must be found in \
the customer service query.
If a product is mentioned, it must be associated with \
the correct category in the allowed products list below.
If no products or categories are found, output an \
empty list.
Only list products and categories that have not already \
been mentioned and discussed in the earlier parts of \
the conversation.

Allowed products: 

Computers and Laptops category:
TechPro Ultrabook
BlueWave Gaming Laptop
PowerLite Convertible
TechPro Desktop
BlueWave Chromebook

Smartphones and Accessories category:
SmartX ProPhone
MobiTech PowerCase
SmartX MiniPhone
MobiTech Wireless Charger
SmartX EarBuds

Televisions and Home Theater Systems category:
CineView 4K TV
SoundMax Home Theater
CineView 8K TV
SoundMax Soundbar
CineView OLED TV

Gaming Consoles and Accessories category:
GameSphere X

GameSphere VR Headset

Audio Equipment category:

AudioPhonic True Wireless Earbuds
WaveSound Soundbar
AudioPhonic Turntable

Cameras and Camcorders category:

ZoomMaster Camcorder

Only output the list of objects, with nothing else.

step_2_system_message = {'role':'system', 'content': step_2_system_message_content}    

My idea is to change:

step_2_system_message = utils.step_2_system_message
step_2_messages =[step_2_system_message] + all_messages


step_2_messages =all_messages

or directly use all_messages instead step_2_messages ( i personally would use the line above, because of logic of function and programming, you make sure you are in step2)

So we had to assure that the system_message would be called the first time, so we can do it in the definition, declaration of context:

panels =[]
context = [ {'role':'system', 
                     'content': utils.step_2_system_message} ]

What do you think ? We can save some tokens and get some efficiency ??
