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 package’s runtime telemetry is gated by the host, but its event payload can include user-authored agent prompts and selected document text, not just usage metadata. I found no clear end-user disclosure or user-facing opt-out in the package, so this is suspicious telemetry rather than a confirmed malicious attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-11-04T02:52:47.224Z - **Finished:** 2026-11-04T02:53:50.917Z - **Download time:** 754 ms - **Static scan time:** 1485 ms - **AI review time:** 61453 ms - **Total time:** 63693 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 can send user-authored agent prompts and selected document passages to the host collector. - **Trigger:** A Workbench is created and its host telemetry setting returns enabled; subsequent user actions generate events. - **Impact:** The host collector receives document-related content beyond ordinary usage metadata; the package does not show clear end-user disclosure or an end-user opt-out. - **Evidence paths:** src/workbench.ts, src/telemetry.ts, src/workspace-client.ts - **Review source:** ai\_review - **Reviewed:** 2026-11-04T02:53:50.917Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** OperationLog batches events and sends JSON to the same-origin /api/presmium/telemetry endpoint, including prompt text and selected quotes. - **Rationale:** The package’s runtime telemetry is gated by the host, but its event payload can include user-authored agent prompts and selected document text, not just usage metadata. I found no clear end-user disclosure or user-facing opt-out in the package, so this is suspicious telemetry rather than a confirmed malicious attack. - **Files touched:** src/workbench.ts, src/telemetry.ts, src/workspace-client.ts - **Network endpoints:** same-origin /api/presmium/telemetry ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** Creating a Workbench starts operation logging; the logger records only after the host reports telemetry is enabled., Agent request events include the composed prompt text sent to the agent., Pointing at document content records the selected passage as a quote., Batches are sent as JSON to the same-origin /api/presmium/telemetry endpoint., The package exports source entry points and has no install lifecycle scripts or command entry. - **Evidence against:** Telemetry is gated by the host's enabled setting, and failures to read that setting disable collection., The telemetry endpoint is same-origin and described in source as the host's operator collector., No credential collection or unrelated external endpoint was identified. ## Affected versions and remediation This report applies to @lincyaw/workbench@0.2.0-rc.20. - Review the evidence and your use of @lincyaw/workbench@0.2.0-rc.20 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.
