Skills are a key part of the multi-skill AI assistants. DeepPavlov Dream provides a set of built-in capabilities, referred to as skills. For example, in one of the distributions, Deepy, AI assistant’s abilities include talking about Moonbase and having a chit-chat. In bigger distributions like Dream it also can answer factoid questions (using Factoid QA), provide weather forecasts, and can support a smarter chit-chat.
DeepPavlov Dream lets you teach your AI assistant new skills. Customers can access these new abilities by asking your AI assistant questions or making requests. You can build skills that provide users with many different types of abilities.

In general, skills can be seen as either goal-oriented or chit-chat-based. However, there may be different types of skills, and hence different ways to classify them.
Goal-oriented skills are focused on solving particular user problems. They usually usually have a number of intents they can recognize, with [optionally] accompanying slots and entities, and may or may not be scenario-driven.
An example of a goal-oriented skill is our Harvesters Maintenance Skill. It can answer to questions like:
These skills can be implemented using rules, using neural networks, or their combination.
You can use any kind of a framework to build your Goal-Oriented Skills. We provide DFF (Dialog Flow Framework) that enables development of the goal-oriented skills using scenario-driven approach. Take a look at various dff_*_skill in the /skills directory for details.
FAQ Skills are focused on supporting Q&A/FAQ style of conversation. AI Assistant’s creator supplies a curated list of questions and answers, uses DeepPavlov library to train a model on top of that list, and then uses the model as a foundation of the FAQ Skill.
Chit-chat skills are focused on supporting a general conversation; it may be completely generic or more domain- or topic-specific.
An example of a chit-chat skill is our Program Y Skill. It supports discussion on a number of topics including but not limited to:
These skills can be implemented using rules (e.g., AIML), neural models (e.g., seq2seq or seq2word like GPT), and their combinations.
You can use any kind of a framework to build your Chit-Chat Skills.
You can re-use existing DFF-based skills by replacing their contents with your own code. The easiest way is to use dff_template_skill, then begin adding your own logic to its scenario/main.py file, either manually or with the aid of DF Designer.

You use our bare-bones Harvesters Maintenance Skill, then remove the rest of the contents keeping only /respond endpoint and Flask app default boilerplate code:
#!/usr/bin/env python
import logging
import time
import random
import re
import json
from flask import Flask, request, jsonify
from os import getenv
import sentry_sdk
logging.basicConfig(format="%(asctime)s - %(name)s - %(levelname)s - %(message)s", level=logging.INFO)
logger = logging.getLogger(__name__)
app = Flask(__name__)
@app.route("/respond", methods=["POST"])
def respond():
st_time = time.time()
dialogs = request.json["dialogs"]
responses = []
confidences = []
for dialog in dialogs:
sentence = dialog['human_utterances'][-1]['annotations'].get("spelling_preprocessing")
if sentence is None:
logger.warning('Not found spelling preprocessing annotation')
sentence = dialog['human_utterances'][-1]['text']
response = "Hello world!"
confidence = 0.8
responses.append(response)
confidences.append(confidence)
total_time = time.time() - st_time
logger.info(f"harvesters_maintenance_skill exec time = {total_time:.3f}s")
return jsonify(list(zip(responses, confidences)))
if __name__ == "__main__":
app.run(debug=False, host="0.0.0.0", port=3000)
You will need to appropriately process the user’s utterance coming either directly from the user, or after being processed by the Spell Checking annotator when available (as shown above). After that you will need to provide the confidence of your skill’s response. Finally, you’ll need to send both the respond and the confidence back to the DeepPavlov Agent.
