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 entry point and inspected code implement Google Antigravity authentication and model requests, with no install hook or unrelated credential destination found. The flagged process execution opens the user’s OAuth URL in a browser, while network calls target Google services or retrieve public pricing data. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-11-01T09:56:51.758Z - **Finished:** 2026-11-01T09:57:37.657Z - **Download time:** 1029 ms - **Static scan time:** 2136 ms - **AI review time:** 42733 ms - **Total time:** 45899 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 source behavior matches an OpenCode Google Antigravity authentication and model-provider plugin. - **Trigger:** The host application activates the plugin; OAuth browser launch and credential exchange occur when the user starts authorization, and authenticated requests occur when the provider is used. - **Impact:** No malicious behavior or unrelated collection was identified. Normal use sends model requests to the configured Google provider. - **Review source:** ai\_review - **Reviewed:** 2026-11-01T09:57:37.657Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The plugin handles Google OAuth and routes model requests to Google endpoints. It also fetches public pricing data and writes local cache and authentication files. - **Rationale:** The package entry point and inspected code implement Google Antigravity authentication and model requests, with no install hook or unrelated credential destination found. The flagged process execution opens the user’s OAuth URL in a browser, while network calls target Google services or retrieve public pricing data. - **Files touched:** OS temporary directory/agy-pricing-cache.json-${uid}, ${XDG\_CONFIG\_HOME:-~/.config}/opencode/antigravity-signature-cache.json, ~/.local/share/opencode/auth.json - **Network endpoints:** models.dev, accounts.google.com, oauth2.googleapis.com, www.googleapis.com, antigravity.google, daily-cloudcode-pa.googleapis.com, generativelanguage.googleapis.com, cloudcode-pa.googleapis.com ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json points to dist/index.js and declares no install, preinstall, or postinstall hook., The plugin offers Google OAuth authorization through accounts.google.com and exchanges the code at oauth2.googleapis.com., Stored OAuth credentials are used by the request interceptor for Google model and Cloud Code Assist requests., Process spawning is used to open the OAuth URL in a browser; pricing data is cached locally. - **Evidence against:** The bundle contains process execution, filesystem access, environment access, and network calls, but these serve OAuth, model-provider, and cache functions., The pricing lookup contacts models.dev during plugin activation; the source shows it requests pricing data and caches the response, without sending host or project data. ## Affected versions and remediation This report applies to @anthonyhaussman/opencode-agy-auth@1.4.12. - Review the evidence and your use of @anthonyhaussman/opencode-agy-auth@1.4.12 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.
