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 inspected lifecycle hook installs Chromium, and the runtime network code supports documentation ingestion. No concrete malicious behavior was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-14T15:35:39.372Z - **Finished:** 2026-10-14T15:36:11.449Z - **Download time:** 1027 ms - **Static scan time:** 362 ms - **AI review time:** 30688 ms - **Total time:** 32077 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 in the inspected source. The install hook sets up a browser, while the exported fetchers retrieve documentation. - **Trigger:** Package installation for browser setup, or a consumer calling a fetcher. - **Impact:** No harmful effect was established from the inspected behavior. - **Review source:** ai\_review - **Reviewed:** 2026-10-14T15:36:11.449Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook runs Playwright’s Chromium installer; runtime fetchers retrieve HTML or Context7 documentation for knowledge ingestion. - **Rationale:** The inspected lifecycle hook installs Chromium, and the runtime network code supports documentation ingestion. No concrete malicious behavior was found. - **Network endpoints:** https://context7.com/api/v2/context ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The install hook runs Playwright’s Chromium installer., The HTML fetcher retrieves a supplied source URL and converts its content to Markdown., The Context7 fetcher uses the Context7 API to retrieve documentation. - **Evidence against:** The scanner flagged an install hook and network usage; the inspected source shows browser setup and documentation retrieval, with no confirmed attack behavior. ## Affected versions and remediation This report applies to @devflow-tools/knowledge-engine@0.18.56. - Review the evidence and your use of @devflow-tools/knowledge-engine@0.18.56 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.
