Thinking:

Analyzing Authentication Strategy

I’m currently focused on dissecting the provided code snippets to understand the proposed authentication flow, especially the “refresh token logic.” My immediate task is to identify how best to integrate these pieces into a coherent Python script that reliably manages GitHub Copilot authentication, focusing on the robustness of the token refreshing mechanism.

Refining Copilot Token Management

I’m now zeroing in on integrating the provided refresh token logic within a comprehensive structure for Copilot authentication. My focus is on synthesizing a complete implementation in Python, which should incorporate all necessary parts like GitHub token handling and the Copilot token exchange. I am also working on adding the functionality that was requested specifically, and handling the logic where the access token is returned.

I will implement a Python script that integrates the GitHub Device Flow for authentication, handles Copilot token exchange, and maintains a background refresh loop as requested.

Implementation Plan

1. Authentication Flow: Implement get_device_code and poll_for_access_token using GitHub’s OAuth API.
2. Token Exchange: Implement get_copilot_token to exchange the GitHub OAuth token for a temporary Copilot session token.
3. LLM Interaction: Implement call_copilot_llm to demonstrate using the cached token with the Copilot API.
4. Background Refresh: Integrate the threading logic you provided to keep the Copilot token valid indefinitely.

I’ll start by creating the copilot_proxy.py script.

This implementation includes:

• Device Flow Authentication: Uses the GitHub CLI Client ID to get an OAuth token.
• Persistence: Saves the GitHub token to ~/.copilot_github_token with restricted permissions.
• Threaded Refresh: Periodically updates the short-lived Copilot session token (which usually expires in 25-30 minutes).
• LLM Integration: A working call_copilot_llm function that uses the VS Code editor headers required by the Copilot API.

You can run this script to authenticate and start using Copilot in your CLI applications.
