What Changed

Usage → Limits now shows Antigravity Gemini session and weekly remaining quota from the Google login stored for that instance. Claude and GPT buckets from the same login are omitted. API-key and Vertex connections still report as unsupported.

Mobile /usage-limits and the pooled Limits screen get an Antigravity label so that snapshot is readable there too.

Why

Antigravity could already be signed in, but Limits never asked it for quota, so the provider never appeared. That is #10919.

The health check cannot spawn ACP just to read remaining quota. This reads acp_token.json, refreshes the Google token, and calls daily-cloudcode-pa.googleapis.com retrieveUserQuotaSummary. The cloudcode-pa host answers the same RPC with remainingFraction: 1 on every bucket, so remaining has to come from the daily host.

#10903 is a larger Antigravity quota probe with extra endpoints and UI sorting. This PR only fills the existing Limits cards.

Fixes #10919

UI Changes

Before, top of Limits. Codex, Claude, Cursor. No Antigravity.

Before: Limits tab, top of the list

Before, end of Limits. Cursor, then OpenCode.

Before: Limits tab, end of the list

After. OpenCode, then Antigravity with Gemini session and weekly remaining.

After: Limits tab with Antigravity Gemini limits

Summary by CodeRabbit

  • New Features

    • Added Antigravity subscription usage tracking, including Gemini five-hour and weekly quota windows.
    • Usage limits are refreshed during health checks and session startup, and cleared when signing out.
    • Added support for OAuth personal and business sign-ins, token refresh, and optional enterprise project configuration.
    • Added a user-facing “Antigravity” driver label in usage displays.
  • Documentation

    • Documented Antigravity’s supported subscription limits and authentication requirements, including exclusions for Claude, GPT, API-key, and Vertex usage.

Limits skipped Antigravity even when a Google login was present. Probe
the daily Cloud Code quota summary and map Gemini windows onto the
existing Limits cards.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR adds a production Cloud Code quota integration that reads and refreshes Google OAuth credentials, performs network requests during Antigravity health checks, and exposes new user-facing limits. The unresolved medium-severity findings around post-login refreshes and expired tokens add concrete runtime risk requiring human review.

Not approved because:

  • 2 blocking correctness issues found at or above your repo's Minimum Blocking Severity

Adjust the Minimum Blocking Severity for this repo — including turning it Off — in Settings. You can add or adjust custom eligibility rules. Learn more.

Limits stayed on the pre-login unsupported snapshot until the next
health check, and an expired stored access token skipped refresh and
failed the quota read. Re-probe on session start, and retry Cloud Code
once after a 401.

Walkthrough

Antigravity now reads Google Cloud Code quota data, maps Gemini session and weekly limits, publishes limits through provider health checks, clears them on sign-out, and displays the provider label in mobile usage views.

Some valid grouped Gemini quota responses can be shown as unsupported rather than displaying limits. This is a narrow reporting gap, but should be corrected when practical.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Use the complete period alias set when deriving the group slug.

periodOf accepts session, five_hour, five-hour, week, and 168h. groupSlug does not accept these aliases.

If a group has no displayName, a bucket such as gemini-session produces the slug "group". isGeminiSlug then rejects the valid Gemini quota, and the result becomes unsupported.

Use one shared suffix pattern in both parsing paths. Add a regression test for a group without displayName.

Proposed fix
+const PERIOD_SUFFIX =
+  /-(?:weekly|week|wk|5h|7d|168h|session|five_hour|five-hour)$/i;
+
 function groupSlug(group: typeof QuotaGroup.Type): string {
   for (const bucket of group.buckets ?? []) {
     const id = bucket.bucketId?.trim();
     if (!id) continue;
-    const separator = id.lastIndexOf("-");
-    if (separator <= 0) continue;
-    const suffix = id.slice(separator + 1).toLowerCase();
-    if (suffix === "weekly" || suffix === "5h" || suffix === "7d" || suffix === "wk") {
-      return id.slice(0, separator).toLowerCase();
-    }
+    const slug = id.replace(PERIOD_SUFFIX, "");
+    if (slug !== id) return slug.toLowerCase();
