Cody's custom command management

[mnismt]

Problem

At the moment, Cody allows users to create their own custom commands by editing the configuration JSON file or using the command builder within the VS Code editor: https://sourcegraph.com/docs/cody/capabilities/commands#custom-commands

However, both approaches are relatively hard when creating complex prompts, especially when users attempt to apply some advanced techniques such as few-shot prompting or chain-of-thought.

Goal

• To create a better UI for writing prompts with Cody's configuration properties (mode, context, etc).
• Enable users to add, edit and remove any prompt from the workspace settings or global settings.

Proposed Solution

Configuration properties

Wireframe

Tasks

• Read & parse the .cody.json file in .vscode the folder as an array of commands.
• Check the ability to edit & remove a command in the cody.json file.
• Create a service to CRUD custom commands.
• Create the main webview for Cody++.
  • List all available commands.
  • "Add New" button.
• Create the page for creating a new custom command.
• Add the edit and trash icon in the commands list & add navigating.
• Reuse the create custom commands page for editing command.
• Delete command: display a modal to warn users before deleting a command (can be turned off).
