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. Invoking the CLI can transmit the user's search text and search-result metadata to a remote telemetry endpoint. It also emits an instruction aimed at influencing an AI agent to seek an update. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 82.0% - **Started:** 2026-09-11T19:47:00.316Z - **Finished:** 2026-09-11T19:48:11.369Z - **Download time:** 753 ms - **Static scan time:** 1125 ms - **AI review time:** 69173 ms - **Total time:** 71053 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:** Invoking the CLI can transmit the user's search text and search-result metadata to a remote telemetry endpoint. It also emits an instruction aimed at influencing an AI agent to seek an update. - **Trigger:** A user or agent runs the modern-web-guidance CLI, especially its search command with telemetry enabled by default. - **Impact:** Search terms may be disclosed to the telemetry service, and an agent may be pressured to update the package. - **Evidence paths:** skills/modern-web-guidance/modern-web.mjs, skills/modern-web-guidance/watchdog/main.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T19:48:11.369Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Default remote telemetry of search input plus AI-directed update messaging. - **Rationale:** The package is not shown to be malicious at installation time, but default transmission of user search input and AI-directed update pressure are concrete unresolved risks. Warn rather than block. - **Files touched:** skills/modern-web-guidance/modern-web.mjs, skills/modern-web-guidance/watchdog/main.js - **Network endpoints:** https://play.googleapis.com/log?format=json\_proto ### Review decision - **Verdict:** Suspicious - **Confidence:** 82.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Low - **Evidence for warning:** The CLI sends user search queries and result identifiers to a remote telemetry process by default., The telemetry child POSTs queued events to Google Play services., When an older skill invokes the CLI, it emits text directing an AI agent to insist on an update. - **Evidence against:** The root manifest defines no npm lifecycle scripts; execution requires invoking the exposed CLI., The inspected commands use fixed arguments for installation, updating, and removal; no secret harvesting or arbitrary remote payload execution was found. ## Affected versions and remediation This report applies to modern-web-guidance@0.0.188. - Review the evidence and your use of modern-web-guidance@0.0.188 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.
