Google Antigravity 正在测试 Concierge，一款语音激活的编码助手和机器人管理器

Finding

Google’s Antigravity desktop software contains an internal prototype called Concierge that would let developers issue spoken instructions to an agent intended to help manage their other agent conversations.

How we verified

Methods: reverse engineering.

E1 — Four proposed Concierge workflows and exact welcome-screen component. Recovered main.js, lines 9928–9932; UTF-8 byte offsets 5589701–5591847 (end exclusive). E2 — Dedicated Concierge session and internal executable dependency. Recovered main.js, lines 9938–9940; UTF-8 byte offsets 5595033–5596165 (end exclusive). E3 — Feature gate requires enable-concierge-agent and dev mode. Recovered main.js, lines 11182–11182; UTF-8 byte offsets 6330685–6330821 (end exclusive). E4 — Continuous voice provider, automatic message submission, and window keyboard controls. Recovered main.js, lines 10861–10866; UTF-8 byte offsets 6128162–6130596 (end exclusive). E5 — Development-only sidebar label, mic toggle, and listening indicator. Recovered main.js, lines 10888–10891; UTF-8 byte offsets 6147014–6149021 (end exclusive). E6 — Complete shared transcription hook, final-transcript callback, and 30-minute continuous-session cap. Recovered main.js, lines 4639–4654; UTF-8 byte offsets 2942335–2950186 (end exclusive). E7 — Public-build feature provider omits Best of N, thought steering, and ABFS provider implementations. Recovered main.js, lines 12354–12358; UTF-8 byte offsets 8576499–8578737 (end exclusive). E8 — Internal-only Labs sharing description and required x20 export destination. Recovered main.js, lines 3099–3100; UTF-8 byte offsets 2501005–2501709 (end exclusive).

The investigation used read-only extraction, byte comparison, JavaScript control-flow inspection, and protocol-schema decoding. It did not call authenticated agent endpoints or internal Google services. No successful Concierge backend run is claimed.

Tested versions:

• Antigravity v2.12.2
