Mycroft Skills Kit

Learn how to use the Mycroft Skills Kit - MSK - to make the creation, testing and submission of Skills a lot easier.
The Mycroft Skills Kit - msk - is a Python-based utility that has been created to make it easier for Skill Authors to create, test and submit Skills to the Mycroft Skills Repo. We hope this utility helps to shorten the development cycle, and remove some of the tedious parts of Skill creation.
msk currently supports the following features:
Create a new Skill
Create an Intent test for a Skill
Upload a Skill
Upgrade an existing Skill
Installing msk
NOTE: msk has only been tested on Linux systems
msk comes pre installed on the Mark 1, Picroft and the git installation of Mycroft-core. The utility is self-contained and can be installed separately using pip by typing the following line into the terminal on your Linux system:
pip3 install msk
You should then see output like the below:

Usage
The normal commands for msk are:
msk create
msk create-test /opt/mycroft/skills/myskill
msk upload /opt/mycroft/skills/myskill
msk upgrade /opt/mycroft/skills/myskill
If using the built-in installation of msk with a Mycroft device or Mycroft git installation, use mycroft-msk in place of msk:
mycroft-msk create
mycroft-msk create-test /opt/mycroft/skills/myskill
mycroft-msk upload /opt/mycroft/skills/myskill
mycroft-msk upgrade /opt/mycroft/skills/myskill
Create
Next, we use the msk create function. You will be prompted to enter the required information to help set up your Skill.
$ msk create
Enter a short unique skill name (ie. "siren alarm" or "pizza orderer"):
Feed the Corgi
​
Class name: FeedTheCorgiSkill

>
Enter some example phrases to trigger your skill:
- Have I fed the Corgi today

-

Create test
msk also provides a function for creating Intent tests, as part of our Automated Testing for Skills.
Please see this ASCII Cinema video to see the process for using msk create-test:
​​​​
As before if the mycroft-core github installation is used make sure to use mycroft-msk or activate the mycroft-core Python virtual environment. From the mycroft-core folder
$ source .venv/bin/activate
Next, we use the msk create-test function. You must pass the Skill directory location to the command, or it will fail.
$ msk create-test /opt/mycroft/skills/feed-the-corgi-skill/
​
Which intent would you like to test?
1. corgi.the.feed.intent
​
> 1
​
=== Intent Examples ===
Corgi the feed
​
Enter an example query: have I fed the corgi today?
​
Choose expected dialog (leave empty to skip).
1. corgi.the.feed
​
> 1
Generated test file: /opt/mycroft/skills/feed-the-corgi-skill/test/intent/corgi.the.feed.intent.0.intent.json
If we have a look inside the corgi.the.feed.intent.0.intent.json file we can see that the test has been created for us.
$ cat /opt/mycroft/skills/feed-the-corgi-skill/test/intent/corgi.the.feed.intent.0.intent.json
{
    "intent_type": "corgi.the.feed",
    "expected_dialog": "corgi.the.feed",
    "utterance": "have I fed the corgi today?"
}
Upload Skill
msk also provides a function for uploading a Skill to the Mycroft Skills Repo, as part of our [Skill Submission Process] (https://mycroft.ai/documentation/skills/skill-submission/).
Please see this ASCII Cinema video to see the process for using msk upload:
​​​​
If using the msk delivered with the mycroft-core github installation be sure to use mycroft-msk or activate the mycroft-core Python virtual environment. From the mycroft-core folder
$ source .venv/bin/activate
You will now see that your bash prompt is prefixed with (venv).
Next, we use the msk upload command with the path to the Skill:
$ msk upload /opt/mycroft/skills/feed-the-corgi-skill/

Upgrade Skill
msk also provides a function for upgrading a Skill once it has been merged into the Mycroft Skills Repo, as part of our [Skill Submission Process] (https://mycroft.ai/documentation/skills/skill-submission/).
Before you upgrade
Before you can use msk upgrade, you must ensure:
That your Skill has already been merged with the mycroft-skills repo.
That you have made changes to your Skill and that these changes have been committed to the Skill's git repository.
Once your changes are committed, you can then use msk upgrade by passing the location of the Skill folder. Generally we find it's easiest to be inside the Skill's folder in /opt/mycroft/skills/SKILL-NAME and then use the current directory symbol, period .
(.venv) kathyreid@kathyreid-Oryx-Pro:/opt/mycroft/skills/kathy-msk-test-skill$ msk upgrade .
