feat(oauth): add Gemini OAuth (Google account) accounts with Code Assist and AI Studio subtypes - #2230
feat(oauth): add Gemini OAuth (Google account) accounts with Code Assist and AI Studio subtypes#2230ppvia wants to merge 2 commits into
Conversation
Adds "OAuth login (Gemini)" to the Add provider modal's Accounts tab: sign in
with a Google account and pick the OAuth subtype.
- gemini-cli (Code Assist): the Gemini CLI first-party client on
cloudcode-pa. Shares the v1internal transport with Antigravity but is a
distinct client family — plain {model, project, request} envelope and a
GeminiCLI/<ver> User-Agent, never the antigravity IDE fingerprint. Project id
is discovered via loadCodeAssist/onboardUser at login and on refresh.
- gemini-ai-studio: generativelanguage.googleapis.com with an OAuth bearer
instead of an API key. Requires operator-registered client credentials and
fails closed with an actionable message when they are unset.
Both endpoints stay pinned (no allowBaseUrlOverride) so the Google bearer
cannot follow an operator-set URL. gemini-cli sends the bare model id: the
-tiered spelling is an AI Studio deployment quirk that Code Assist does not
serve.
Docs: en + zh-cn provider guides and the adapters reference.

📝 WalkthroughWalkthroughAdded separate Gemini Code Assist and AI Studio OAuth providers. Added Gemini CLI Google adapter transport, project discovery, token handling, provider registration, account labels, risk handling, tests, and documentation. ChangesGemini provider support
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🔵 Low · up to The change adds Gemini OAuth account options and project onboarding, but the new account labels may remain English in non-English locales and failed onboarding can wait an unnecessary extra interval after the final poll. The PR is mergeable with explicit owner awareness and follow-up on these bounded issues. Sequence Diagram(s)sequenceDiagram

- Line 60: Update the OAuth provider entries in the Japanese, Korean, and
Russian provider guides to include gemini-cli and gemini-ai-studio, revise the
stated OAuth preset count from eight to ten, and add the Gemini OAuth login
section with both login commands, matching the existing zh-cn guide content and
structure.
In `@docs-site/src/content/docs/reference/adapters.md`:
- Around line 118-119: Update the cloud-code-assist and gemini-cli entries in
the adapter reference table to document the pinned hostname as
cloudcode-pa.googleapis.com with the v1internal path form, while preserving
their existing OAuth descriptions and the Google adapter’s four-mode
endpoint/credential coverage.
In `@gui/src/pages/providers-shared.ts`:
- Around line 52-55: Move the user-visible Gemini labels out of the hardcoded
oauthLabel mapping and into the locale catalogs for every supported locale.
Preserve “gemini-cli” and “gemini-ai-studio” as stable provider IDs, add
corresponding translation keys, and resolve them via TKey/TFn at the account-row
construction or render boundary in oauthLabel/providers-page-utils.
In `@src/oauth/gemini-cli.ts`:
- Around line 215-244: Separate transient retry and in-progress polling budgets
in onboardProject, preserving immediate failure for hard 4xx responses and
allowing onboarding polling its own full duration. Return a distinguishable
timeout outcome when onboarding remains incomplete, propagate it through
discoverGeminiProject, and update exchangeToken to report that onboarding did
not finish rather than blaming missing entitlement. Add a focused regression
test alongside the existing OAuth tests covering repeated done:false responses
and asserting the timeout outcome.
In `@src/oauth/index.ts`:
- Around line 230-241: Add defaultRefreshPolicy: "lazy-only" only to the
GEMINI_CODE_ASSIST_PROVIDER entry, keeping GEMINI_AI_STUDIO_PROVIDER unchanged.
Follow the existing explicit policy pattern used by entries such as nous and
github-copilot.
In `@src/providers/registry.ts`:
- Around line 1573-1576: Update the gemini-ai-studio provider metadata to use an
explicit AI Studio model catalog and context, input-modality, and
reasoning-effort constants rather than GEMINI_CLI_* values. Ensure the catalog
excludes Cloud Code Assist-only models and accurately reflects AI Studio
capabilities, including the image support of gemini-3.1-pro-preview; do not
create the metadata via spread copies of the CLI constants.
In `@tests/gemini-cli-oauth.test.ts`:
- Around line 40-48: Replace the self-derived environment assertion in the
“code-assist is always configured; ai-studio needs operator client credentials”
test with assertions for the fail-closed contract owned by geminiOAuthClient and
GeminiOAuthClientNotConfiguredError. Add coverage for missing credentials,
including whitespace-only values, and verify the actionable error type/message
without mutating process.env after module import; retain the code-assist
configured assertion.

Use an AI Studio-specific Gemini catalog.
GEMINI_CLI_* is scoped to the Cloud Code Assist host, but gemini-ai-studio uses https://generativelanguage.googleapis.com. Sharing these constants can expose a Code Assist-only model on the AI Studio route and cause a 404. The shared metadata also marks gemini-3.1-pro-preview as image-capable, unlike the google entry.
Define explicit AI Studio metadata, or rename the constants only if both hosts support identical models and capabilities. Do not use spread copies of the CLI constants.

Separate the onboarding retry budgets and keep the failure reason: - onboardProject gave transient 429/5xx retries and in-progress polls one shared counter, so a couple of 5xx responses could exhaust the budget before Google finished provisioning. Transient retries now draw on their own budget. - Onboarding that is merely slow was reported the same way as an account without Code Assist access, sending users to look for a problem that does not exist. discoverGeminiProjectOutcome now returns ready/pending/ unavailable and the login error distinguishes the two. - discoverGeminiProject keeps its boolean-ish contract for the refresh path, which stays lenient on purpose. Pin the Code Assist refresh policy to lazy-only. Each refresh also re-runs project discovery against Google's own CLI client identifiers, so proactive refresh would multiply traffic under identifiers we do not own. Replace a tautological subtype test with two that assert real contracts, and add regression coverage for the separated budgets, the pending outcome, the hard-4xx outcome, the exhausted transient budget, and the refresh policy. Docs: correct the gemini-cli host in the adapters reference (it is cloudcode-pa, not the Antigravity daily- host), and mirror the English Gemini updates into the six remaining locale guides — provider table rows, both login commands, the OAuth auth-mode row, the preset count, and the full OAuth login (Gemini) section.

Hollow subtype test — the original assertion was tautological. Replaced with two tests that assert something falsifiable: that both subtypes derive from the registry with a real Skipped, with reasons3. GUI labels not routed through i18n — 6.

Do not wait after the final onboarding poll.
At Line 261, polls can reach ONBOARD_ATTEMPTS. Line 262 then waits for ONBOARD_POLL_MS even though the loop exits immediately afterward. This adds two seconds to the pending-login result and delays cancellation handling.

Reviewed exact head 154fe3be7142388396287f37e2e74cb5f38f7b35. I independently checked the current automated findings and the author response.
The hardcoded Gemini product-label finding is a false positive under gui/AGENTS.md, which explicitly allows company/product names; I replied and resolved that thread.
Two blockers remain:
gemini-ai-studiotargetsgenerativelanguage.googleapis.combut still reuses the Cloud Code Assist-scopedGEMINI_CLI_*model and capability constants. Generic generated metadata does not prove that the OAuth AI Studio endpoint exposes the same account-scoped catalog. Use endpoint-specific metadata or provide a real AI Studio account/endpoint contract test that establishes identical model ids and capabilities before sharing a named constant.onboardProjectstill sleeps forONBOARD_POLL_MSafter incrementing the final poll toONBOARD_ATTEMPTS, adding an unconditional two-second delay before the pending result. Skip the sleep when no poll remains and add a bounded timing/call-count regression.
This OAuth/security surface is also 62 integration commits behind current dev. Rebase first, preserve the existing previous-credential metadata merge in the shared refresh path, rerun the focused OAuth/GUI/docs checks and exact-head CI, and request a fresh security review before applying maintainer-sponsored or merging.

Summary
Adds OAuth authorization with a Google account to the Add provider modal's Accounts tab, modelled on the Gemini authorization flow in sub2api. Two OAuth subtypes ship as two independent provider ids, each with its own account set and registry entry:
gemini-clicloudcode-pa.googleapis.comgemini-ai-studiogenerativelanguage.googleapis.comWhy two ids rather than one entry with a subtype field. Google gates the two behind different OAuth clients and different scopes, and the accounts are not interchangeable — a Code Assist credential cannot serve an AI Studio request. Separate ids let each keep its own credential set and its own login button state, and let the existing account plumbing work unmodified.
Flow (
src/oauth/gemini-cli.ts): standard Google OAuth with PKCE (S256) on loopback port51122— deliberately distinct from Antigravity's51121so a Gemini login cannot land on a callback server already listening for an Antigravity one. For the Code Assist subtype the flow then discovers the Cloud Code Assist project vialoadCodeAssist, falling back toonboardUser(polling the default entitled tier fromallowedTiers) when the account has none yet. The discoveredprojectIdis stored on the credential and injected into the request envelope by the google adapter, as the Antigravity flow already does.Adapter (
src/adapters/google.ts). The two Code Assist client families share the/v1internal:{action}endpoint and theresponsewrapper but are not interchangeable, sogoogleMode: "gemini-cli"selects the CLI's plain{model, project, request}envelope andGeminiCLI/<ver>User-Agent, versus Antigravity's{model, userAgent, requestType, project, requestId, request}andantigravity/ide/<ver>. Theai-studiosubtype reuses the existing Generative Language transport but sends an OAuth bearer instead ofx-goog-api-key, branching onauthMode.Fail-closed behaviour
restricted_client, login fails immediately with a message naming the two env vars to set. The row's hint states the requirement before the user clicks.allowBaseUrlOverrideon either entry. Unlike Antigravity (which has daily and prod hosts and so needs the override), both Gemini endpoints are a single fixed host. Pinning them keeps the Google OAuth bearer from following an operator-set URL — seesrc/lib/destination-policy.tsandsrc/router.ts.extraMetadataAliases: ["gemini"]. That alias already belongs to thegoogleentry; a second claim would shadow it. Both ids still resolve model metadata throughjawcodeBundle: "google".Credentials disclosure
src/oauth/gemini-cli.tsembeds the Gemini CLI's client id and secret. These are the public OAuth client identifiers Google ships inside the Gemini CLI binary, not user secrets — the same shape as the Antigravity client already ondevatsrc/oauth/google-antigravity.ts:18,20. Both are overridable viaGEMINI_CLI_OAUTH_CLIENT_ID/GEMINI_CLI_OAUTH_CLIENT_SECRETfor operators who prefer their own registered client. Tokens and refresh tokens are never logged.Docs
Usage help was added to
docs-sitein both English and Simplified Chinese (guides/providers.md,zh-cn/guides/providers.md) plus the envelope/User-Agent distinction inreference/adapters.md: which subtype to pick, what each requires, how to register an AI Studio client, and the Code Assist project-discovery behaviour.Screenshot
