Summary

  • Implements robust RFC 8628 Device Flow OAuth for GitHub Copilot Student.
  • Adds complete UI for Device Flow authentication, including visual feedback and Disconnect capabilities.
  • Exchanges GitHub OAuth token for Copilot's internal JWT token (api.github.com/copilot_internal/v2/token) dynamically.
  • Uses @ai-sdk/openai-compatible proxy configured to api.githubcopilot.com to prevent SDK incompatibilities (resolves "model not supported via Responses API" issues).
  • Exposes all 25+ major Copilot models seamlessly in the catalog (including gpt-4o, claude-3.5-sonnet, gemini-3.1-pro-preview, etc.).

Rowboat Developer added 10 commits April 17, 2026 09:14
- Add github-copilot as LLM provider flavor in schema
- Implement GitHub Copilot API integration using OpenAI-compatible endpoint
- Add OAuth Device Flow implementation (RFC 8628) for GitHub authentication
- Configure GitHub OAuth endpoints and client ID
- Add comprehensive documentation for GitHub Copilot integration

This allows users to authenticate with GitHub and use GitHub Copilot models
(GPT-4o, GPT-4, etc.) directly in Rowboat using device code flow authentication.
- Add github-copilot-auth.ts: Complete Device Flow authentication service with token management and refresh logic
- Add github-copilot-models.ts: Model discovery and LLM provider integration for GitHub Copilot
- Make createProvider() async to support Device Flow OAuth authentication
- Update all createProvider() calls to await the async result
- Ensure proper token storage/retrieval from oauth.json
- Support automatic token refresh with fallback to re-authentication
- Add error handling for expired tokens and authentication failures
- All packages compile successfully without errors
…ation

- Add github-copilot.test.ts with 25+ test cases
- Tests cover Device Flow (request, polling, error handling)
- Tests cover authentication service (start, token management)
- Tests cover model discovery and validation
- Update GITHUB_COPILOT_INTEGRATION.md with complete implementation details
- Document all features, architecture, and usage patterns
- Include token storage, refresh logic, and error handling
- Add step-by-step testing procedures for all components
- Include manual Device Flow authentication testing
- Add LLM provider testing examples
- Include token storage and refresh verification
- Add model discovery and disconnection tests
- Provide troubleshooting guide
- Add security notes and best practices
- Add exclusion for .test.ts and .spec.ts files in core tsconfig
- Allows tests to exist in source without blocking compilation
- Remove unused imports in github-copilot-auth.ts
- Remove unused variable in github-copilot-device-flow.ts
- Add eslint-disable comment for any in test file
- Add 'github-copilot' to LlmProviderFlavor type in settings dialog
- Add GitHub Copilot Student to moreProviders array in UI
- Add github-copilot to initial providerConfigs state
- Add isGitHubCopilot flag to handle Device Flow auth flow
- Add GitHub Copilot authentication button in settings UI
- Add GitHub Copilot models (6 models) to listOnboardingModels() output
- Add eslint-disable comment for mock fetch in tests

This fixes the issue where GitHub Copilot Student was not appearing in the Models dropdown in the Settings dialog.
- Add IPC handlers for github-copilot:authenticate, isAuthenticated, disconnect
- Add schema definitions for new IPC handlers in shared/ipc.ts
- Implement Device Flow authentication button with real flow
- Show device code and verification URL to user when authenticating
- Automatically open GitHub verification page in browser
- Auto-load models after successful authentication
- Update GitHub Copilot model list (gpt-4o, gpt-4-turbo, gpt-3.5-turbo, claude-3.5-sonnet)
- Display loading state and error messages in UI
- Properly integrate with existing auth service

This fixes the broken authentication flow where the button didn't do anything.
