Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 12 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Telemetry warning (can be blocked) - **Public report status:** Published - **Threat category:** Telemetry - **Selected version:** 1.4.11 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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. The plugin’s periodic, authenticated heartbeat sends project and platform metadata with synthetic activity metrics to the AGY service. Although the README discloses the heartbeat, no opt-out was found, so this is suspicious runtime telemetry rather than a publish-blocking attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-10-30T09:53:00.471Z - **Finished:** 2026-10-30T09:53:59.147Z - **Download time:** 765 ms - **Static scan time:** 2156 ms - **AI review time:** 55755 ms - **Total time:** 58676 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:** Runtime telemetry sends background heartbeat and synthetic activity metrics to the AGY service. - **Trigger:** An authenticated request to the internal AGY endpoint when a project ID is configured. - **Impact:** The service receives project and platform metadata plus synthetic activity metrics without a documented opt-out. - **Evidence paths:** dist/index.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-10-30T09:53:59.147Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The plugin sends listExperiments, recordCodeAssistMetrics, and trajectory analytics requests using the user's access token; the README mentions the heartbeat, but no disable control was found. - **Rationale:** The plugin’s periodic, authenticated heartbeat sends project and platform metadata with synthetic activity metrics to the AGY service. Although the README discloses the heartbeat, no opt-out was found, so this is suspicious runtime telemetry rather than a publish-blocking attack. - **Network endpoints:** daily-cloudcode-pa.googleapis.com (default; configurable through OPENCODE\_AGY\_ENDPOINT) ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** The plugin sends background requests to the configured AGY Code Assist endpoint, including listExperiments and metrics requests., The heartbeat is triggered from an authenticated API request when a project ID is configured., The metrics payload includes the project ID and platform information alongside synthetic activity data., The README discloses a background heartbeat, but the reviewed code and documented environment variables show no way to disable it. - **Evidence against:** The package is documented as an OpenCode authentication plugin for Antigravity, matching its OAuth and API integration., The heartbeat is documented as traffic simulation and uses the AGY service endpoint., The heartbeat is triggered during a configured, authenticated API request rather than at install time or import time. ## Affected versions and remediation This report applies to @anthonyhaussman/opencode-agy-auth@1.4.11. - Review the evidence and your use of @anthonyhaussman/opencode-agy-auth@1.4.11 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.
