Egonex AI Installation Guide: Setting Up Understand Anything for Claude Code, Codex, Cursor, and Copilot

Egonex AI installation varies by platform, using marketplace commands for Claude Code, a curl-based installer for Codex and OpenCode, and repository auto-discovery for Cursor and GitHub Copilot.

Understand Anything is an open-source, multi-agent code analysis tool developed by Egonex AI. It functions as a cross-platform plugin that parses source code, constructs a knowledge graph, and exposes slash commands like /understand and /understand-dashboard. The Egonex AI installation process adapts to each host environment—whether Claude Code, Codex, Cursor, or GitHub Copilot—using platform-specific discovery mechanisms while deploying the same core engine, React dashboard, and skill definitions.

Installation Methods by Platform

The plugin architecture consists of three components: the core analysis engine in understand-anything-plugin/packages/core, the React dashboard in understand-anything-plugin/packages/dashboard, and the agent skills in understand-anything-plugin/skills/understand and understand-anything-plugin/agents/*. Each platform discovers these components differently.

Claude Code (Marketplace Plugin)

Claude Code discovers Understand Anything through its native marketplace registry. The platform loads skill definitions from the skills/understand/*.md files at runtime.

Run the following commands inside Claude Code:

/plugin marketplace add Egonex-AI/Understand-Anything
/plugin install understand-anything

These commands register the plugin and make the /understand, /understand-dashboard, and /understand-chat commands available immediately.

Codex and OpenCode (CLI Installer)

For Codex, OpenCode, and other CLI-based platforms, use the standalone installer script. This method executes install.sh with a platform-specific argument and places files in ~/.understand-anything-plugin or platform-specific locations.

Install via curl:

curl -fsSL https://raw.githubusercontent.com/Egonex-AI/Understand-Anything/main/install.sh | bash -s codex

Replace codex with opencode or other supported CLI identifiers as needed.

Cursor (Auto-Discovery)

Cursor auto-discovers the plugin via the .cursor-plugin/plugin.json descriptor after you clone the repository.

Clone the repository to activate auto-discovery:

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

If auto-discovery does not trigger, manually add the plugin via Settings → Plugins and paste the repository URL https://github.com/Egonex-AI/Understand-Anything.

GitHub Copilot (VS Code and CLI)

GitHub Copilot supports two installation paths depending on your interface.

For VS Code (Copilot v1.108+), clone the repository to enable auto-discovery via .copilot-plugin/plugin.json:

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

Alternatively, install personal skills across all projects using the install script:

curl -fsSL https://raw.githubusercontent.com/Egonex-AI/Understand-Anything/main/install.sh | bash -s vscode

For Copilot CLI, use the native plugin command:

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

Plugin Components and File Structure

After installation, the plugin deploys the following key directories:

• understand-anything-plugin/packages/core – The parsing engine and graph builder that analyzes source files.
• understand-anything-plugin/packages/dashboard – The React + TypeScript UI for visualizing the knowledge graph and running semantic searches.
• understand-anything-plugin/skills/understand – Markdown skill definitions containing slash command handlers.
• understand-anything-plugin/agents/* – Multi-agent pipeline modules including the project scanner and graph reviewer.

Both Cursor and Copilot rely on JSON descriptors—.cursor-plugin/plugin.json and .copilot-plugin/plugin.json respectively—to locate these components without additional configuration.

Available Commands After Installation

Once installed, the following slash commands become available in your IDE or terminal:

• /understand – Initiates project scanning and knowledge graph construction.
• /understand-dashboard – Launches the React visualization interface.
• /understand-chat – Opens an interactive chat session with the analyzed codebase context.

Summary

• Claude Code requires two marketplace commands to register and install the plugin from the registry.
• Codex and OpenCode use a single curl-piped bash script with a platform argument.
• Cursor relies on repository cloning and auto-discovery via .cursor-plugin/plugin.json.
• GitHub Copilot supports auto-discovery for VS Code (v1.108+) or direct CLI installation via copilot plugin install.
• All methods deploy the same three-component architecture to ~/.understand-anything-plugin or equivalent platform directories.

Frequently Asked Questions

Can I install Egonex AI on multiple platforms simultaneously?

Yes. The plugin files are platform-agnostic. You can clone the repository once for Cursor and VS Code Copilot auto-discovery while also installing via marketplace or CLI commands for Claude Code and Codex. Each instance reads from the same skill definitions in understand-anything-plugin/skills/understand.

Where are the plugin files stored after installation?

The installer places files in ~/.understand-anything-plugin or platform-specific plugin directories. The core engine, dashboard, and agents reside under this path, while platform descriptors like .cursor-plugin/plugin.json remain in the cloned repository root to facilitate auto-discovery.

What commands become available after installing Understand Anything?

The installation exposes /understand for graph construction, /understand-dashboard for launching the visualization UI, and /understand-chat for contextual code queries. Additional agent-driven commands are defined in the agents/* directory and loaded by the host platform.

Do I need to clone the repository for Cursor or Copilot VS Code integration?

Yes. Both Cursor and VS Code Copilot (v1.108+) require the repository to be cloned locally so they can read the auto-discovery descriptors .cursor-plugin/plugin.json and .copilot-plugin/plugin.json. Copilot CLI users can skip cloning and install directly via the copilot plugin install command.
