I am developing a todo system for team which can understand text like this.

   - @john Generate a list of pokemons , when queried . Need to complete within 3 days  for [Pokelist]
   - show rarity in the ui list  @joe , high proity.
   - When stock is low , manufacuring order need to be automatically generated @Ashley  , Urgently needed for +Warehouse project. 

I just want to write like i would assign tasks to my team , but the it need to understand for example

Urgently as priority , High Priority as priority , @mention as assignees , +Project as project.

I could write a parser but , i would like it to be more intelligent.

What should i use? Spacy,Flair , Or LLMs? I want to host it my self for team so , CPU infrencing is necessary as my server dont have gpu.
