That points to a service-level suspension (Antigravity \/ Cloud Code Assist \/ Gemini CLI backends) rather than a universal account lock\u2014though some users fear broader spillover because many Google services are identity-linked.<\/p>\n<h2>What OpenClaw and AntiGravity Auth actually are<\/h2>\n<p>\u201cAntiGravity\u201d here is not a generic term: Google Antigravity is positioned by Google as an \u201cagentic development platform\u201d that goes beyond autocomplete to orchestrate autonomous agents across editor, terminal, and browser surfaces. Google\u2019s own developer materials emphasize a \u201cMission Control\u201d style interface and \u201cagent-first\u201d workflows.<\/p>\n<p>In parallel, Google\u2019s Gemini CLI is described in official developer documentation as an open source AI agent that runs in the terminal using a \u201creason and act (ReAct) loop,\u201d with quotas tied to Gemini Code Assist editions and an option to use a Gemini API key for pay-as-you-go.<\/p>\n<p>OpenClaw (the third-party tool at the center of these reports) markets itself as a local-first \u201copen agent platform\u201d that runs on your machine and connects through chat surfaces (Telegram\/WhatsApp\/Discord\/Slack, etc.), rather than being a pure SaaS assistant.<\/p>\n<p>Where this becomes risky is how OpenClaw integrates with Google\u2019s agent stack. OpenClaw\u2019s own documentation distinguishes several \u201cGoogle\u201d lanes:<\/p>\n<ul>\n<li>A Gemini API key path (a conventional developer integration) that expects an API key.<\/li>\n<li>A separate \u201cAntigravity OAuth\u201d path shipped as a bundled plugin (disabled by default in docs), and described elsewhere in OpenClaw docs\/tests as an \u201cAntigravity OAuth bridge\u201d that behaves like a \u201cCloud Code Assist-style agent endpoint.\u201d<\/li>\n<\/ul>\n<p>This distinction matters because it explains why many users experienced the bans as puzzling: from the user\u2019s perspective, they \u201clogged in with Google\u201d inside a tool; from Google\u2019s internal perspective (and per the quoted support reply), the result can look like using Antigravity\u2019s backend to power a non-Antigravity client.<\/p>\n<p>You can see how \u201cnon-official client\u201d behavior arises in the OpenClaw code ecosystem itself: OpenClaw pull requests and issues discuss updating \u201cclient identity\u201d metadata and headers to satisfy Antigravity server-side checks, implying that Antigravity endpoints enforce expectations about what the calling client should look like.<\/p>\n<h2>What the evidence says about the ban wave<\/h2>\n<p>The ban pattern is not supported solely by anecdotes; it appears across multiple independent channels with consistent error messaging.<\/p>\n<p>On the Google AI Developers Forum, affected users describe:<\/p>\n<ul>\n<li>Immediate or sudden disablement after integrating a third-party client with Antigravity OAuth, with the recurring 403 copy: \u201cThis service has been disabled in this account for violation of Terms of Service.\u201d<\/li>\n<li>The \u201cunexpected issue setting up your account\u201d Antigravity login failure concurrent with Gemini Code Assist errors.<\/li>\n<li>Confusion over escalation paths, with some users reporting being bounced between support channels (Google Cloud vs. subscription support), and long waits for responses via the published feedback email.<\/li>\n<li>Most importantly, one forum participant posted a reply they attribute to Google support after \u201cfull investigation,\u201d stating the suspension affects \u201cGemini CLI and any other service that uses the Cloud Code Private API,\u201d and that the use of credentials in \u201copen claw\u201d violated Google Terms of Service because it used \u201cAntigravity servers to power a non-Antigravity product,\u201d with \u201czero tolerance\u201d and no reversal.<\/li>\n<\/ul>\n<p>On Reddit, a widely shared thread frames the situation as \u201caggressive banning\u201d of users using Antigravity\/Gemini OAuth with third-party tools, again anchored on the same 403 \u201cdisabled for ToS violation\u201d outcome, including paid AI Pro subscribers.<\/p>\n<p>Within the OpenClaw project itself, an issue filed February 11, 2026 summarizes the same dual symptom set\u2014Gemini CLI login failures with the ToS disablement message and Antigravity setup failures\u2014explicitly linking to the forum thread and Reddit posts as \u201ccommunity reports,\u201d and urging removal of those auth methods to protect users.<\/p>\n<p>A separate meta-signal: OpenClaw\u2019s own changelog (2026.2.23) shows the project ultimately removed Google Antigravity provider support and the bundled google-antigravity-auth plugin, explicitly instructing migration to other providers. This is a strong indicator that maintainers concluded the risk\/fragility of Antigravity OAuth integration outweighed its value.<\/p>\n<h2>Why OAuth token rerouting trips Terms of Service and security enforcement<\/h2>\n<p>It\u2019s tempting to treat this as \u201cGoogle is banning automation,\u201d but the policy collision is narrower and sharper: it\u2019s about who a token is meant for, what backend it unlocks, and how the resulting traffic is interpreted.<\/p>\n<p>OAuth itself is an authorization framework that lets a third-party application obtain limited access on a user\u2019s behalf via tokens. Those tokens are powerful enough\u2014and in many ecosystems, portable enough\u2014that if a tool can obtain them and relay them elsewhere, it can effectively \u201cborrow\u201d the identity and privileges associated with the original authorized client.<\/p>\n<p>From Google\u2019s policy perspective, the key points are:<\/p>\n<ul>\n<li>Google\u2019s Terms of Service require users not to \u201cabuse\u201d services or protective measures, and explicitly prohibit behaviors like \u201cbypassing\u2026 protective measures,\u201d \u201creverse engineering\u2026 except as allowed,\u201d and \u201cproviding services that appear to originate from us when they do not.\u201d<\/li>\n<li>Google\u2019s API Services User Data Policy requires developers to accurately represent identity and intent, prohibits deceptive or unauthorized use, and notes Google may revoke\/suspend access to Google API Services (and sometimes other products) for noncompliance or if an app enables violations.<\/li>\n<li>Google\u2019s OAuth policies add constraints around secure origins\/redirects and user-agent handling, reflecting a broader expectation that OAuth flows\u2014and the apps behind them\u2014conform to specific security and transparency rules.<\/li>\n<\/ul>\n<p>Now connect that to what users and maintainers report was happening technically:<\/p>\n<ul>\n<li>OpenClaw documentation characterizes the \u201cgoogle-antigravity\u201d integration as an OAuth \u201cbridge\u201d to a Cloud Code Assist-style endpoint rather than the public Gemini API key endpoint.<\/li>\n<li>A forum support reply (as posted) says the violation is that Antigravity servers were used \u201cto power a non-Antigravity product.\u201d<\/li>\n<\/ul>\n<p>That combination\u2014non-official client + official backend\u2014is exactly the shape that triggers platform enforcement across many ecosystems: the provider subsidizes or rate-limits a service assuming first-party client behaviors, telemetry, and abuse controls, then sees traffic that (a) doesn\u2019t match the expected harness and (b) may amplify cost\/abuse risk.<\/p>\n<p>Some community members go further and hypothesize concrete detection signals (WAF\/risk engines, client fingerprinting, proxy patterns, token usage anomalies). Those details are not independently verified, but they are consistent with the existence of \u201cserver-side client\/version checks\u201d discussed in OpenClaw pull requests and user reports of automated sweeps. Treat these as plausible interpretations, not confirmed mechanisms.<\/p>\n<h2>Practical risk management for AI enthusiasts and developers<\/h2>\n<p>The most important operational takeaway is that \u201cGoogle sign-in works\u201d does not mean \u201cthis use is permitted.\u201d A third-party tool can complete an OAuth flow and still put your account in violation depending on what it does with the resulting tokens and what backend it calls.<\/p>\n<p>The safest pattern, repeatedly reinforced by both Google\u2019s own developer ecosystem and the post-incident maintainers\u2019 decisions, is:<\/p>\n<ul>\n<li><strong>Use official, intended access channels.<\/strong> If you are building tooling around Gemini models, the Gemini API + API key route is explicitly documented and bounded by published terms (and is structurally different from piggybacking on an IDE subscription backend).<\/li>\n<li><strong>Avoid OAuth \u201cbridges\u201d that route subscription entitlements through unofficial clients.<\/strong> OpenClaw\u2019s later changelog explicitly removes Antigravity provider support and tells users to migrate away, underscoring that this path became untenable.<\/li>\n<li><strong>Assume your local agent environment is a high-value credential target.<\/strong> Agent frameworks often store API keys and tokens locally. Security reporting has already highlighted infostealer malware extracting OpenClaw configuration data, with the risk that stolen secrets could unlock connected apps\/accounts.<\/li>\n<\/ul>\n<p>Relatedly, access tokens are designed to be short-lived, while refresh tokens extend access\u2014so an attacker who steals the right artifacts can potentially maintain access beyond a single session.<\/p>\n<p>If you experiment anyway, separate blast radius. Community members frequently advise using non-primary accounts for risky experimentation. That advice is not a cure, but it is rational risk containment when identity-linked services (email, storage, subscriptions) matter.<\/p>\n<h2>Recovery reality and what affected users report doing<\/h2>\n<p>Recovery is inconsistent, and some reports indicate irreversible outcomes\u2014so any \u201cfix list\u201d must be framed as best-effort, not guaranteed restoration.<\/p>\n<p>What \u201crecovery\u201d looks like in practice is evident in the forum threads:<\/p>\n<ul>\n<li>Users are repeatedly told (by community members and moderators) to contact the dedicated email shown in the error message (commonly gemini-code-assist-user-feedback@google.com) and to file in-product feedback when possible.<\/li>\n<li>Some users explicitly report revoking connected app access, removing the third-party tool\/proxy, and then attempting appeals\u2014again with uncertain response times.<\/li>\n<li>Others describe escalating through subscription support channels (e.g., Google One) because the disablement is tied to personal subscriptions rather than a typical Google Cloud billing account\u2014though even those escalation loops are described as confusing and slow.<\/li>\n<li>The harshest constraint appears in the posted \u201cinvestigation\u201d reply that claims zero-tolerance and \u201cunable to reverse the suspension\u201d once the system concludes Antigravity servers were used to power a non-Antigravity product. If accurate and representative, this means prevention is far more effective than remediation.<\/li>\n<\/ul>\n<p>Finally, even if the suspension is service-scoped (Antigravity\/Gemini Code Assist), users should consider data resilience. Google\u2019s own Terms note that in certain situations Google may provide an opportunity to export content via Google Takeout when services change or stop (subject to law\/policy)\u2014a reminder that account-level dependencies deserve backups.<\/p>\n<h2>Broader implications for AI agents and \u201csubscription token arbitrage\u201d<\/h2>\n<p>The OpenClaw\/Antigravity situation is part of a broader pattern: model providers sell subscriptions priced for \u201chuman-in-the-loop\u201d interactive usage, while open source agents and third-party harnesses can generate traffic patterns (and costs) closer to API workloads. The incentives push users toward \u201csubscription token arbitrage\u201d\u2014routing high-volume agent usage through subscription entitlements rather than metered APIs\u2014until providers clamp down.<\/p>\n<p>Anthropic\u2019s recent clarification\u2014explicitly forbidding the use of OAuth subscription tokens in third-party harnesses and explaining the support\/telemetry problems created by unusual traffic\u2014shows that Google is not alone in viewing this as an existential product-economics and abuse-control issue.<\/p>\n<p>In that light, Google\u2019s Antigravity enforcement wave can be read less as an anti-open-source stance and more as an attempt to preserve a boundary: Antigravity\u2019s OAuth-backed agent backend is intended to be consumed by Antigravity (and closely related first-party clients), while open ecosystem integrations are expected to use published APIs and keys. That boundary is stated bluntly in the forum-quoted support reply (\u201cuse of Antigravity servers to power a non-Antigravity product\u201d).<\/p>\n<p>What this leaves the ecosystem with is a gap: users want interoperability between the best harness (agent UX) and the best models, while providers want cost control, telemetry, and a defensible business model. Until providers offer sanctioned \u201cbring your own harness\u201d subscription tiers\u2014or until third-party tools standardize on metered APIs\u2014the ban-wave dynamic is likely to recur across vendors.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A wave of user reports has converged on the same failure mode: after authenticating third-party \u201cagent\u201d tooling with Google Antigravity \/ Gemini CLI OAuth&hellip;<\/p>\n","protected":false},"author":1,"featured_media":6875,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-6874","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news"],"_links":{"self":[{"href":"https:\/\/toolswift.com\/blog\/wp-json\/wp\/v2\/posts\/6874","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/toolswift.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/toolswift.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/toolswift.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/toolswift.com\/blog\/wp-json\/wp\/v2\/comments?post=6874"}],"version-history":[{"count":1,"href":"https:\/\/toolswift.com\/blog\/wp-json\/wp\/v2\/posts\/6874\/revisions"}],"predecessor-version":[{"id":6876,"href":"https:\/\/toolswift.com\/blog\/wp-json\/wp\/v2\/posts\/6874\/revisions\/6876"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/toolswift.com\/blog\/wp-json\/wp\/v2\/media\/6875"}],"wp:attachment":[{"href":"https:\/\/toolswift.com\/blog\/wp-json\/wp\/v2\/media?parent=6874"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/toolswift.com\/blog\/wp-json\/wp\/v2\/categories?post=6874"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/toolswift.com\/blog\/wp-json\/wp\/v2\/tags?post=6874"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
