Runtime: Node.js >= 20 and either GitHub Copilot CLI or VS Code Copilot Chat.

​
VS Code

Install from the VS Code Marketplace. After VS Code installs the extension, run: 
Copilot Goal System: Install Recommended Setup
The Marketplace install button installs the VS Code wrapper. The command above installs the local goal system for your current OS account:
  • Copilot CLI stable adapter
  • VS Code Copilot Chat preview adapter
  • local MCP goal tools
  • lifecycle hooks
  • the Goal System custom agent
After extension updates, VS Code checks whether ~/.copilot/extensions/goal-system/ is older than the bundled runtime. If it is stale, the status bar switches to Goal Update and VS Code prompts you to update the local Copilot files.

​
Terminal

Install directly from the published docs site: 
curl -fsSL https://gabrimatic.github.io/copilot-goal-system/install.sh | bash
Install both adapters: 
curl -fsSL https://gabrimatic.github.io/copilot-goal-system/install.sh | bash -s -- --target all
Or clone the repository: 
git clone https://github.com/gabrimatic/copilot-goal-system.git
cd copilot-goal-system
./install.sh

​
Reload Copilot

For CLI mode, restart Copilot CLI, then run: 
/skills reload
/env
For VS Code Chat, reload VS Code or run MCP: Reset Cached Tools, then select the Goal System custom agent in Copilot Chat.
