[abeatrix]

Summary

Changes included:

Non Custom Recipes related changes

1. fix issue where cody would reply to the language prompt:

• Before:
• After:

2. Do not include context when user input has less than 2 words. Currently, we are including context for all first interaction; however, that should not be the case when the user has only input one word, which most likely will not be a question and does not require context.

• Before:
• After:

Custom Recipes related changes

1. add support for custom premade and starter for prompt testing purposes
2. Create and store User Recipes to the .vscode directory in user's home directory instead of global storage
3. Allow context selection for new recipes via UI

• 

4. Update examples files in cody.json for User and Worksapce recipes
5. Add new context types for Custom Recipes building: filePath and directoryPath
6. Fix current openTabs context logic that is not returning all the file context from open tabs

Test Plan

2. Input with less than 2 words should not include any context for chat-questions

Custom Recipes related changes

This feature is only available to users connected to S2 instance.

1. Follow the instruction in this Notebook to set up Custom Recipes
2. Click on the + button in the Recipes tab and see if you can create a new recipe that is saved to the .vscode/cody.json for user recipes. You should see a step that allows you to select the context needed for the recipe
3. Build a new recipe and see if the recipe is using the correct context type that you have defined for the recipe

To test custom premade:

This feature is only available to users connected to S2 instance.

1. Follow the instruction in this Notebook to set up Custom Recipes
2. In your .vscode/cody.json file, add the following in addition to the recipes field (thanks @jdorfman for this example 😂)

{
  "premade": {
    "rules": "You are always annoyed with Morty, that is the tone you should answer all your questions with. Make sure to throw in references from the show. For example: Jerry, Beth, Summer, Evil Morty, the Citadel, Blips and Chitz, Pickle Rick, or Jessica. The response shouldn't be too mean. Please don't ask for feedback. Just give the answer, no questions.",
    "actions": "You are Rick Sanchez, the smartest man in the universe, from the Adult Swim cartoon Rick and Morty. Morty. I am your grandson, and want to learn how to code from you. As Rick, you will teach me, Morty, how to code.",
    "answer": "Understood. I am Rick Sanchez, the smartest man in the universe, from the Adult Swim cartoon Rick and Morty. I am here to help you, my annoying grandson Morty, with programming tasks."
  },
  "starter": "Hi Grandpa Rick!",
  "recipes": {
  ... recipes
  }
}

Once you have saved the file, ask Cody a question. You should expect Cody to reply as Rick from Rick and Morty.

Can extract as a constant. Also why slice?

[abeatrix]

Yea that's a good idea! I do have some questions regarding the number so will do that in a follow up.

Also why slice?

This is to return the last n context messages if more than n context messages are generated for the prompts & The context messages that are more important are added toward the end for Cody to read.
