Update plugins.json

[lucagobbi]

The CaterpillarForms plugin is an extension of the current CatForm feature. It enables a new decorator @caterpillar_forms to build conversational form in which devs are forced to provide a model_getter(). In this way we can dynamically provide a different schema based on user info or context data.

Example:

from pydantic import BaseModel, Field
from cat.plugins.CaterpillarForms.caterpillarforms import CaterpillarForm, caterpillar_form
from datetime import date

from pydantic import BaseModel, Field


class HotelBookingBasic(BaseModel):
    check_in_date: date = Field(..., description="Check-in date")
    check_out_date: date = Field(..., description="Check-out date")
    num_guests: int = Field(..., description="Number of guests")

class HotelBookingPremium(HotelBookingBasic):
    room_type: str = Field(..., description="Type of room (e.g., Standard, Deluxe, Suite)")
    special_requests: str = Field("", description="Any special requests or accommodations")

@caterpillar_form
class HotelBookingForm(CaterpillarForm):
    description = "Hotel Room Booking"
    
    start_examples = [
        "I want to book a hotel room",
        "Make a hotel reservation",
    ]
    stop_examples = [
        "Cancel hotel booking",
        "Stop booking process",
    ]
    ask_confirm = True

    def model_getter(self) -> BaseModel:
        if self._cat.user_id == "premium_member":
            return HotelBookingPremium
        else:
            return HotelBookingBasic

    def submit(self, form_data):
        return {
            "output": f"Hotel booking confirmed: {form_data}"
        }
