Problem

T3 Code's Antigravity quota probe sends antigravity/hub/1.0.0 as its User-Agent. For that client version, Google's retrieveUserQuotaSummary returns only the shared Claude/GPT buckets (3p-*). Gemini quota buckets (gemini-weekly, gemini-5h) are never returned, so the composer and thread card have no Gemini row to render.

Verified against all four authenticated Antigravity profiles:

User-Agent	Buckets returned
`antigravity/hub/1.0.0`	`3p-weekly`, `3p-5h`
`antigravity/hub/2.24.0`	`gemini-weekly`, `gemini-5h`, `3p-weekly`, `3p-5h`

The same fix was proposed in #23011 (now conflicted). This is a clean rebase against current main.

Change

One line in apps/server/src/provider/antigravityUsageLimits.ts:

diff

1	- "User-Agent": `antigravity/hub/1.0.0 (aidev_client; ...)`,
2	+ "User-Agent": `antigravity/hub/2.24.0 (aidev_client; ...)`,

With 2.24.0 (the version the Antigravity IDE itself sends, per @DeepitMagee's capture in #21115), the daily endpoint returns consumed Gemini buckets on personal accounts. The existing endpoint merge in antigravityUsageLimits.ts already keeps the most-used reading across both endpoints, so no other code changes are needed.

Fixes #27448. Supersedes #23011 (conflicted).

Maintainer follow-up

With 2.24.0, accounts with Argon quota get both the real gemini-weekly bucket and gemini-argon-*-weekly. Both were labeled "Gemini · Weekly". Argon buckets now keep their group name ("Gemini 4 Argon · Weekly"). This fix and its test come from #23011 by @whoisaldo, credited as co-author.

Live check on one more personal account (quota unused): both versions return all four buckets on both endpoints, so 2.24.0 does not drop anything there.

Model: Claude Opus 5.5 via Claude Code, in T3 Code.

Walkthrough

The Antigravity quota probe now sends User-Agent version 2.24.0. Gemini Argon buckets use their trimmed group name or the Gemini Argon default. Tests check the User-Agent prefix and bucket labels.

Changes: Antigravity quota probe

Layer / File(s)	Summary
Update Gemini Argon bucket labels `apps/server/src/provider/antigravityUsageLimits.ts`, `apps/server/src/provider/antigravityUsageLimits.test.ts`	Gemini Argon buckets use the trimmed group name or `Gemini Argon`. The test checks the Argon label and confirms that the default Gemini label remains unchanged.
Update quota request identity `apps/server/src/provider/antigravityUsageLimits.ts`, `apps/server/src/provider/antigravityUsageLimits.test.ts`	The quota request User-Agent uses hub version `2.24.0` instead of `1.0.0`. The test fixture checks the new prefix. Other User-Agent fields remain unchanged.

Full details: Description check

Explanation

The description explains the problem, the implementation change, the reported verification across authenticated profiles, issue references, scope, and the agent details. It does not use a dedicated "Scope and approval" heading, but it provides enough scope and approval context for this focused bug fix.

Full details: Linked Issues check

Explanation

The change meets #27448. antigravityUsageLimits.ts now sends antigravity/hub/2.24.0, which the PR reports returns Gemini and shared quota buckets. Existing endpoint merging and thread-card rendering expose returned windows. The test fixture checks the new User-Agent. The added test verifies separate labels for gemini-weekly and gemini-argon-wtu-weekly.

Full details: Out of Scope Changes check

Explanation

All changes support #27448. The User-Agent update retrieves the missing quota data. The Argon label change keeps separate Argon quotas visible. The test changes verify both behaviors. No unrelated changes are present in the reviewed diff.

Assert the quota request User-Agent in the existing probe test.

The probe test mocks the Antigravity quota requests and asserts their Authorization header, but it never asserts the User-Agent. This PR changes that header from antigravity/hub/1.0.0 to antigravity/hub/2.24.0, and the change is what makes Gemini quota rows appear. A reversion would not fail any test. Extend the existing mock's assertions rather than adding a new test:
