Installation

Features

CliChecker

Checks if the Copilot CLI is installed and the user is authenticated using the Copilot SDK.

using Refractored.GitHub.Copilot.SDK.Helpers;

// Check status with console output
var status = await CliChecker.CheckCopilotStatusAsync();

// Or check silently (no console output)
var status = await CliChecker.CheckCopilotStatusSilentAsync();

if (!CliChecker.IsReady(status))
{
 Console.WriteLine("Copilot is not ready!");
 return;
}

ModelSelector

Fetches available models from the Copilot SDK and allows selection.

using Refractored.GitHub.Copilot.SDK.Helpers;

// Interactive selection via console
var model = await ModelSelector.SelectModelAsync();

// Get all available models (names only)
var models = await ModelSelector.GetModelsAsync();

// Get models with full info including billing multipliers
var modelsInfo = await ModelSelector.GetModelsWithInfoAsync();
foreach (var modelInfo in modelsInfo)
{
 Console.WriteLine($"{modelInfo.Id}: Multiplier = {modelInfo.Billing?.Multiplier}");
}

// Get the default (first) model
var defaultModel = await ModelSelector.GetDefaultModelAsync();

// Select by index (0-based)
var model = await ModelSelector.SelectModelByIndexAsync(2);

// Optionally pass an existing CopilotClient to reuse the connection
var client = new CopilotClient();
await client.StartAsync();
var models = await ModelSelector.GetModelsAsync(client);

ChatHelper

Helper methods for streaming chat interactions.

using GitHub.Copilot.SDK;
using Refractored.GitHub.Copilot.SDK.Helpers;

// Stream response to console with colored output
await ChatHelper.SendMessageAndStreamResponse(session, "Hello, Copilot!");

// Get complete response as string
var response = await ChatHelper.SendMessageAndGetResponseAsync(session, "What is 2+2?");

// Use callbacks for custom handling
await ChatHelper.SendMessageWithCallbacksAsync(
 session,
 "Explain async/await",
 onDelta: text => Console.Write(text),
 onComplete: () => Console.WriteLine("\n[Done]"),
 onError: err => Console.WriteLine($"Error: {err}")
);

SessionManager

Manages Copilot sessions including listing, resuming, and cleanup.

using GitHub.Copilot.SDK;
using Refractored.GitHub.Copilot.SDK.Helpers;

// List all available sessions with formatted console output
var sessions = await SessionManager.ListSessionsAsync();

// Get sessions without console output
var sessions = await SessionManager.GetSessionsAsync();

// Get the most recently used session ID
var lastSessionId = await SessionManager.GetLastSessionIdAsync();

// Resume the last session
var client = new CopilotClient();
await client.StartAsync();
var session = await SessionManager.ResumeLastSessionAsync(client);

// Delete a specific session
await SessionManager.DeleteSessionAsync("session-id-123");

// Clean up old sessions (older than 7 days)
int deletedCount = await SessionManager.CleanupOldSessionsAsync(TimeSpan.FromDays(7));

// Get CLI version and protocol information
var status = await SessionManager.ShowCliStatusAsync();
Console.WriteLine($"CLI Version: {status.Version}");

// Optionally pass an existing CopilotClient to reuse the connection
var client = new CopilotClient();
await client.StartAsync();
var sessions = await SessionManager.GetSessionsAsync(client);

Prerequisites

• .NET 8.0, .NET 9.0, or .NET 10.0
• GitHub Copilot CLI installed and configured
• GitHub Copilot access on your GitHub account

Installing Copilot CLI

# macOS/Linux (Homebrew)
brew install copilot-cli

# Windows (WinGet)
winget install GitHub.Copilot

# npm (requires Node.js 22+)
npm install -g @github/copilot

# macOS/Linux (install script)
curl -fsSL https://gh.io/copilot-install | bash

Authentication

Either:

• Run copilot, then type /login and follow prompts
• Set GH_TOKEN environment variable with a token that has "Copilot Requests" permission

Full Example

using GitHub.Copilot.SDK;
using Refractored.GitHub.Copilot.SDK.Helpers;

// Check prerequisites
var status = await CliChecker.CheckCopilotStatusAsync();
if (!CliChecker.IsReady(status))
 return;

// Select a model
var model = await ModelSelector.SelectModelAsync();
if (model == null)
 return;

// Start client and create session
using var client = new CopilotClient();
await client.StartAsync();

using var session = await client.CreateSessionAsync(new SessionConfig
{
 Model = model,
 Streaming = true
});

// Chat!
await ChatHelper.SendMessageAndStreamResponse(session, "Hello, Copilot!");
