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. Source inspection shows a postinstall hook that installs Chromium and documentation-fetching code that uses Context7. These behaviors align with the package's browser-backed knowledge ingestion purpose; no concrete attack behavior was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 92.0% - **Started:** 2026-10-12T03:24:14.594Z - **Finished:** 2026-10-12T03:24:48.159Z - **Download time:** 517 ms - **Static scan time:** 356 ms - **AI review time:** 32692 ms - **Total time:** 33565 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. The postinstall hook installs the Chromium browser used by the package's browser-backed fetcher. - **Trigger:** Package installation runs the postinstall hook; network fetching occurs when the exported synchronization or fetch functionality is invoked. - **Impact:** The inspected behavior installs a browser dependency and retrieves documentation; no credential collection or malicious mutation was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-12T03:24:48.159Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook runs Playwright's Chromium installer. The Context7 fetcher requests documentation using a Context7 library identifier and predefined topic queries. - **Rationale:** Source inspection shows a postinstall hook that installs Chromium and documentation-fetching code that uses Context7. These behaviors align with the package's browser-backed knowledge ingestion purpose; no concrete attack behavior was established. - **Files touched:** package.json - **Network endpoints:** context7.com ### Review decision - **Verdict:** Clean - **Confidence:** 92.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The postinstall command installs Chromium through Playwright, consistent with the package's browser-backed documentation fetching., The exported API provides knowledge synchronization and fetch helpers; the Context7 fetcher requests documentation from context7.com when called. ## Affected versions and remediation This report applies to @devflow-tools/knowledge-engine@0.18.46. - Review the evidence and your use of @devflow-tools/knowledge-engine@0.18.46 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.
