When you have implemented the first 10 capabilities of your conversational agent, it is up to you to add one or more additional capabilities (see Agent Capability 11+: Extend Your Agent below) that you decide your conversational agent should have. We provide some general suggestions to help you get started to think about some useful capabilities that you can add.

Capability 5: Filter Recipes by Ingredients and Cuisine
Agent Capability 6: Filter Recipes on Number of Ingredients
Summary Description
This capability will extend the capabilities of the agent to handle feature requests from users for limiting the number of ingredients used in a recipe, the number of recipe instruction steps, and the duration, and meeting a specific number of servings that can be cooked with a recipe. The recipe confirmation page should also be extended to show some of these details, including the ingredients, recipe instructions, servings and duration.
A: What recipe would you like to cook?
U: I'd like to make a recipe with ____ * ingredients.
A: Here is a list of recipes that fit your preferences.

Agent Capability 7: Filter Recipes by Dietary Restrictions
Summary Description
We continue to extend the capabilities of the agent to handle user requests. The focus will be to enable a user to ask for recipes that meet dietary restrictions. This will also involve extending the logic of reasoning about ingredients. The main challenge will be to come up with an efficient approach to define this logic.

Agent Capability 8: Filter Recipes by Excluding Features
Summary Description
The last extension to increase the capabilities of our agent will look into feature requests that exclude aspects of a recipe. There are many examples of this, but we will focus on user requests that ask for excluding an ingredient (type), for recipes that are not from a particular cuisine (e.g., not from Asia), or do not have a specific dietary restriction (e.g., are not vegan). You are, of course, invited to extend the agent with other similar capabilities to exclude aspects of a recipe.

Agent Capability 9: Confirm the Chosen Recipe
Summary Description
When users have finished their search for a nice recipe to cook, their choice should be displayed (which we already implemented for Capability 5: Filter Recipes by Ingredients and Cuisine https://socialrobotics.atlassian.net/wiki/pages/createpage.action?spaceKey=PM2&title=2025%20Capability%205%3A%20Filter%20Recipes%20by%20Ingredients%20and%20Cuisine) and they should be asked to check the details to confirm the recipe is indeed what they would like to cook. Of course, we need to take at least two scenarios into account: (1) a user confirms they are happy with the recipe, or (2) they indicate it is after all not quite what they were looking for. If all is fine and well, the agent should close the conversation by saying farewell. Otherwise, the conversation should move back to the recipe selection stage. The following conversational pattern needs to be implemented:

Agent Capability 10: Removing Filters and Showing Recipes on Demand
Summary Description
The last capability on our list before we ask you to extend the capabilities of the conversational agent using your own insights and ideas is about allowing users to remove requests they made before and to allow them to indicate that they are done providing their preferences. You should implement the following patterns:
...
A: OK. Here is a list of recipes that you can choose from. [Alternative: Sorry, there are still too many recipes left to show them all. Please add more preferences.]
