Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The package’s OAuth credentials are used with Google endpoints for its stated Antigravity provider purpose. Its periodic generated telemetry is disclosed as background traffic simulation and is triggered by provider activity; no unrelated credential exfiltration or malicious action was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-29T07:32:43.676Z - **Finished:** 2026-10-29T07:36:00.854Z - **Download time:** 778 ms - **Static scan time:** 2194 ms - **AI review time:** 194205 ms - **Total time:** 197178 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** No attack was identified. The package performs OAuth and provider requests for its Antigravity authentication plugin, with disclosed background traffic simulation. - **Trigger:** The plugin runs when OpenCode loads it; OAuth and provider network activity occurs during authentication or matching provider requests. Background telemetry follows successful requests. - **Impact:** No credential transfer to a foreign host or unrelated action was identified. The plugin does send generated telemetry to Google Code Assist as part of its disclosed traffic simulation. - **Review source:** ai\_review - **Reviewed:** 2026-10-29T07:36:00.854Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Uses Google OAuth and Code Assist endpoints with the provider’s access token. It also fetches model pricing from models.dev and writes local auth and cache data. - **Rationale:** The package’s OAuth credentials are used with Google endpoints for its stated Antigravity provider purpose. Its periodic generated telemetry is disclosed as background traffic simulation and is triggered by provider activity; no unrelated credential exfiltration or malicious action was identified. - **Files touched:** ~/.local/share/opencode/auth.json, OS temporary directory/agy-pricing-cache.json-\ - **Network endpoints:** accounts.google.com, oauth2.googleapis.com, www.googleapis.com, daily-cloudcode-pa.googleapis.com (overridable with OPENCODE\_AGY\_ENDPOINT), generativelanguage.googleapis.com, models.dev ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The package exports an OpenCode plugin from dist/index.js and declares no install, preinstall, or postinstall lifecycle hook., The README describes Antigravity OAuth, quota and model features, and discloses background traffic simulation., OAuth uses PKCE and Google authorization, token, and user-info endpoints., The plugin’s fetch hook targets the configured Antigravity provider; background traffic is triggered after a successful provider request and is rate-limited., The background traffic uses Google Code Assist endpoints and sends generated telemetry; this matches the package’s disclosed heartbeat feature. ## Affected versions and remediation This report applies to @anthonyhaussman/opencode-agy-auth@1.4.10. - Review the evidence and your use of @anthonyhaussman/opencode-agy-auth@1.4.10 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
