From 7d7cdd25604bda188408e7836e2a68c8d282bec4 Mon Sep 17 00:00:00 2001 From: ProfSynapse Date: Sat, 21 Feb 2026 15:43:52 -0500 Subject: [PATCH 01/20] feat: implement extensible OAuth 2.0 PKCE provider connect system Adds OAuth connect buttons for OpenRouter (official) and OpenAI Codex (experimental) providers. Architecture supports any future LLM provider via the IOAuthProvider interface. Core OAuth infrastructure: - IOAuthProvider interface + OAuthService singleton registry - PKCEUtils: PKCE helpers using crypto.subtle (S256 challenge) - OAuthCallbackServer: ephemeral 127.0.0.1 server, state validation, 5-min timeout, EADDRINUSE handling Providers: - OpenRouterOAuthProvider: port 3000, JSON token exchange, permanent sk-or-... key - OpenAICodexOAuthProvider: port 1455, form-urlencoded exchange, JWT accountId extraction, proactive token refresh (5-min window before ~10-day TTL) LLM adapter: - OpenAICodexAdapter: SSE stream parsing, Bearer + ChatGPT-Account-Id headers, input as array, stream:true + store:false required parameters - OpenAICodexModels: 6 model variants (gpt-5.3-codex through gpt-5.1-codex-mini) UI: - OAuthConsentModal: experimental provider consent dialog - OAuthPreAuthModal: key_label + optional credit_limit pre-auth form (OpenRouter) - GenericProviderModal: OAuth connect button, connected banner, disconnect, auto-clear - ProvidersTab: attachOAuthConfigs(), Platform.isDesktop guard - styles.css: OAuth button and status badge styles Co-Authored-By: Claude Sonnet 4.6 --- src/components/LLMProviderModal.ts | 3 + .../providers/GenericProviderModal.ts | 189 ++++++- .../llm-provider/providers/OAuthModals.ts | 158 ++++++ src/components/llm-provider/types.ts | 25 + src/main.ts | 16 + src/services/llm/adapters/ModelRegistry.ts | 3 + .../openai-codex/OpenAICodexAdapter.ts | 499 ++++++++++++++++++ .../openai-codex/OpenAICodexModels.ts | 113 ++++ src/services/llm/adapters/types.ts | 2 +- src/services/llm/core/AdapterRegistry.ts | 49 ++ src/services/llm/providers/ProviderManager.ts | 9 + src/services/oauth/IOAuthProvider.ts | 124 +++++ src/services/oauth/OAuthCallbackServer.ts | 223 ++++++++ src/services/oauth/OAuthService.ts | 205 +++++++ src/services/oauth/PKCEUtils.ts | 73 +++ src/services/oauth/index.ts | 34 ++ .../providers/OpenAICodexOAuthProvider.ts | 247 +++++++++ .../providers/OpenRouterOAuthProvider.ts | 107 ++++ src/settings/tabs/ProvidersTab.ts | 81 +++ src/types/llm/ProviderTypes.ts | 8 + src/types/llm/index.ts | 3 + styles.css | 77 +++ 22 files changed, 2241 insertions(+), 7 deletions(-) create mode 100644 src/components/llm-provider/providers/OAuthModals.ts create mode 100644 src/services/llm/adapters/openai-codex/OpenAICodexAdapter.ts create mode 100644 src/services/llm/adapters/openai-codex/OpenAICodexModels.ts create mode 100644 src/services/oauth/IOAuthProvider.ts create mode 100644 src/services/oauth/OAuthCallbackServer.ts create mode 100644 src/services/oauth/OAuthService.ts create mode 100644 src/services/oauth/PKCEUtils.ts create mode 100644 src/services/oauth/index.ts create mode 100644 src/services/oauth/providers/OpenAICodexOAuthProvider.ts create mode 100644 src/services/oauth/providers/OpenRouterOAuthProvider.ts diff --git a/src/components/LLMProviderModal.ts b/src/components/LLMProviderModal.ts index 69149fa2..2172b8d6 100644 --- a/src/components/LLMProviderModal.ts +++ b/src/components/LLMProviderModal.ts @@ -20,6 +20,7 @@ import { IProviderModal, ProviderModalConfig, ProviderModalDependencies, + OAuthModalConfig, } from './llm-provider/types';

full data flow verified - Call OAuthService.resetInstance() in main.ts onunload() to prevent callback server leak on plugin disable/reload Tests: - OAuthCallbackServer: use randomized ephemeral ports (port 0 requires source refactor; documented) - OAuthService: restore global.window in afterAll to prevent mock leak - OpenAICodexAdapter: add partial SSE chunk boundary test + concurrent refresh deduplication test (confirms refreshInProgress lock works) - OpenAICodexOAuthProvider: update idToken assertion to expect undefined (PII prevention intent now documented) - jest.config.js: add per-file coverage thresholds for 6 OAuth source files (PKCEUtils 100%, others 80/75/80/80) 527/527 tests pass.

JSON.parse safety in performTokenRefresh: wrap in try-catch, throw LLMProviderError on malformed response. Validate expires_in is a positive number, default to 10 days if missing/invalid. 2. Add request timeouts: 30s for token refresh, 2min for streaming inference. Prevents indefinite hangs on network partition. 3. Fix supportsFunctions inconsistency: model specs now correctly declare supportsFunctions: true (matching adapter capabilities). 4. Extract TOOL_NAMES constant for tool preamble string literals, referencing the two-tool architecture slugs. 5. Add clarifying comment on intentional token refresh duplication between adapter (Node.js https for CORS) and OAuthProvider (fetch). 6. Update test mocks with setTimeout/destroy for ClientRequest compat.
