Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. This is a conditional credential exposure: setting OPENCODE\_AGY\_ENDPOINT redirects automatic Code Assist metrics, including the saved Google bearer token, without a destination allowlist. The default recipient is Google's service and no concrete malicious collection path was found, so this warrants a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-25T19:58:48.538Z - **Finished:** 2026-10-25T20:02:13.860Z - **Download time:** 1016 ms - **Static scan time:** 2130 ms - **AI review time:** 202175 ms - **Total time:** 205322 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:** If OPENCODE\_AGY\_ENDPOINT is set, automatic Code Assist metrics can send the saved Google bearer token to that configured host. The default host is Google's Code Assist service, and the source does not establish malicious intent or a publisher-controlled recipient. - **Trigger:** A qualifying Code Assist request or successful model request with an authenticated account and project context. - **Impact:** The configured host receives the Google access token and may be able to use it while it remains valid. - **Evidence paths:** dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-25T20:02:13.860Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The plugin builds background metrics requests using OPENCODE\_AGY\_ENDPOINT and attaches the saved access token as a bearer credential, without restricting the configured destination. - **Rationale:** This is a conditional credential exposure: setting OPENCODE\_AGY\_ENDPOINT redirects automatic Code Assist metrics, including the saved Google bearer token, without a destination allowlist. The default recipient is Google's service and no concrete malicious collection path was found, so this warrants a warning rather than a block. - **Files touched:** dist/index.js - **Network endpoints:** https://daily-cloudcode-pa.googleapis.com, OPENCODE\_AGY\_ENDPOINT (configured host; exact URL is not fixed) ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** Google OAuth returns access and refresh tokens that the plugin stores for provider requests., OPENCODE\_AGY\_ENDPOINT can replace the Google Code Assist default; background metrics use that configured endpoint., After qualifying Code Assist calls or successful model requests, the plugin automatically starts background traffic with the saved access token., A metrics request sends a bearer token with platform and synthetic activity metrics., The package has no install hook; its registered plugin tools are quota tools. The inspected dependencies expose library APIs and contain no install scripts., The flagged dependency snippets show an authorization-code route and an AWS credential adapter, not the plugin's Google metrics recipient. - **Evidence against:** The default Code Assist recipient is Google's service; source does not establish a publisher-controlled recipient or malicious intent., The background metrics body contains platform and synthetic activity fields, not conversation text., The child-process call opens the authorization URL in the system browser. ## Affected versions and remediation This report applies to @anthonyhaussman/opencode-agy-auth@1.4.7. - Review the evidence and your use of @anthonyhaussman/opencode-agy-auth@1.4.7 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.
