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 lifecycle command is consistent with the declared Playwright dependency and performs browser installation. The inspected network paths serve documentation retrieval through exported runtime functions, with no concrete attack behavior established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-17T02:50:07.229Z - **Finished:** 2026-10-17T02:50:34.570Z - **Download time:** 2303 ms - **Static scan time:** 356 ms - **AI review time:** 24682 ms - **Total time:** 27341 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 install command or fetcher paths. The package installs a browser and exposes documentation retrieval functions. - **Trigger:** Package installation activates the postinstall command; runtime retrieval occurs when callers invoke the exported fetch functions. - **Impact:** The inspected behavior supports browser setup and documentation ingestion; no concrete harmful effect was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-17T02:50:34.570Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall invokes Playwright’s Chromium installer. Runtime fetchers retrieve documentation from Context7 or caller-supplied URLs and repositories. - **Rationale:** The lifecycle command is consistent with the declared Playwright dependency and performs browser installation. The inspected network paths serve documentation retrieval through exported runtime functions, with no concrete attack behavior established. - **Network endpoints:** context7.com, github.com ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The postinstall runs Playwright’s Chromium installation command, and Playwright is a declared dependency., The entrypoint exports documentation fetch functions as runtime APIs., Context7 fetching builds requests to the Context7 API; the general fetcher accepts a caller-provided URL., The GitHub fetcher accepts repository and documentation paths as arguments. ## Affected versions and remediation This report applies to @devflow-tools/knowledge-engine@0.18.67. - Review the evidence and your use of @devflow-tools/knowledge-engine@0.18.67 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.
