How to Set Up Egonex AI Plugin for Cursor or VS Code Copilot: Zero-Configuration Guide

Clone the Egonex-AI/Understand-Anything repository and open it in Cursor or VS Code to automatically activate the plugin via manifest-based auto-discovery—no marketplace installation required.

The Egonex AI "Understand Anything" plugin ships as a zero-configuration extension for Cursor and VS Code Copilot. Unlike traditional marketplace extensions, this plugin leverages repository-level manifest files to enable instant activation without manual installation steps. This guide covers the exact file paths and commands you need to set up the plugin using the auto-discovery architecture implemented in the Egonex-AI/Understand-Anything repository.

Auto-Discovery Architecture

The plugin utilizes editor-specific manifest files located in the repository root to trigger automatic registration. This design eliminates the need for separate extension marketplace installations.

Cursor Manifest File

The .cursor-plugin/plugin.json file enables Cursor to register the plugin immediately upon opening the repository. Located at /.cursor-plugin/plugin.json, this manifest contains the plugin name, version, and entry point that Cursor reads to initialize the extension.

Copilot Manifest File

Similarly, VS Code Copilot discovers the plugin through the .copilot-plugin/plugin.json file at /.copilot-plugin/plugin.json. This manifest mirrors the Cursor configuration and must maintain version synchronization with the core package definition in understand-anything-plugin/package.json.

Step-by-Step Setup Instructions

Follow these commands to activate the plugin in your preferred editor.

Clone the Repository

Start by cloning the repository to your local machine:

git clone https://github.com/Egonex-AI/Understand-Anything.git
cd Understand-Anything

Open in Cursor

Launch Cursor from the repository root to trigger auto-discovery:

cursor open .

Cursor automatically reads .cursor-plugin/plugin.json and loads the plugin without additional configuration.

Open in VS Code with Copilot

For VS Code with GitHub Copilot, open the folder:

code .

The Copilot extension discovers .copilot-plugin/plugin.json and exposes the "Understand Anything" capabilities.

Alternatively, use the CLI command referenced in the README.md:

copilot plugin install Egonex-AI/Understand-Anything:understand-anything-plugin

This command points Copilot to the repository manifest without copying files to your local directories.

Optional Manual Installation

If you need to install the plugin manually—for instance, to custom editor locations—use the provided convenience scripts. The install.sh and install.ps1 scripts detect the target editor and copy the correct manifest files.

For VS Code/Copilot:

./install.sh vscode

For Cursor:

./install.sh cursor

Core Configuration Files

The plugin relies on specific files to maintain version consistency and enable auto-discovery:

• .cursor-plugin/plugin.json – Cursor manifest enabling auto-discovery via the repository root.
• .copilot-plugin/plugin.json – Copilot manifest enabling auto-discovery; must sync with the core package version.
• understand-anything-plugin/package.json – Central version and dependency definition serving as the single source of truth.
• README.md – User documentation containing the copilot plugin install command syntax and badge links.
• install.sh and install.ps1 – Cross-platform scripts for manual installation scenarios and edge cases.

Summary

• The Egonex AI plugin uses repository-level manifest files (.cursor-plugin/plugin.json and .copilot-plugin/plugin.json) to enable zero-step installation.
• Opening the cloned repository in Cursor or VS Code automatically triggers plugin registration through auto-discovery.
• The understand-anything-plugin/package.json serves as the single source of truth for version management across all manifest files.
• Convenience scripts (install.sh and install.ps1) provide manual installation options for edge cases or custom directory structures.

Frequently Asked Questions

Do I need to install the plugin from the marketplace?

No. The Egonex-AI/Understand-Anything repository implements auto-discovery through manifest files. When you clone the repository and open it in Cursor or VS Code, the editors automatically read the respective .cursor-plugin/plugin.json or .copilot-plugin/plugin.json files to register the plugin without marketplace interaction.

What if the plugin doesn't load automatically?

Verify that the manifest files exist in the repository root. Check that /.cursor-plugin/plugin.json or /.copilot-plugin/plugin.json are present and contain valid JSON. If auto-discovery fails, run the appropriate installation script: ./install.sh cursor for Cursor or ./install.sh vscode for VS Code Copilot.

Can I use this plugin with both editors simultaneously?

Yes. The repository contains separate manifest files for each editor. You can open the same cloned repository in both Cursor and VS Code Copilot, and each editor will independently discover and load the plugin using its respective configuration file.

How do I update the plugin version?

Update the version field in understand-anything-plugin/package.json, which serves as the single source of truth. You must synchronize this version with the version fields in both .cursor-plugin/plugin.json and .copilot-plugin/plugin.json to maintain consistency across editors.
