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 flagged install hook performs Playwright Chromium setup, and the inspected runtime network and Git behavior is consistent with documentation ingestion. No concrete malicious behavior was found in the reviewed source. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 95.0% - **Started:** 2026-10-14T15:35:39.288Z - **Finished:** 2026-10-14T15:36:19.705Z - **Download time:** 1017 ms - **Static scan time:** 363 ms - **AI review time:** 39036 ms - **Total time:** 40417 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 behavior was identified. The install hook sets up a browser dependency, while the reviewed network and Git operations support documentation retrieval. - **Trigger:** Installation runs the postinstall browser setup; retrieval operations run when their APIs are called. - **Impact:** No malicious impact was established from the inspected source. - **Review source:** ai\_review - **Reviewed:** 2026-10-14T15:36:19.705Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The package installs Chromium and retrieves documentation from Context7, GitHub repositories, or a supplied URL. - **Rationale:** The flagged install hook performs Playwright Chromium setup, and the inspected runtime network and Git behavior is consistent with documentation ingestion. No concrete malicious behavior was found in the reviewed source. - **Files touched:** package.json, dist/context7-fetcher.js, dist/git-fetcher.js, dist/fetcher.js, dist/index.js - **Network endpoints:** https://context7.com/api/v2/context, https://github.com/{repo}.git ### Review decision - **Verdict:** Clean - **Confidence:** 95.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The postinstall hook installs Playwright’s Chromium browser and tolerates failure., Context7 retrieval requests documentation from the fixed Context7 API., GitHub retrieval clones the caller-specified repository using Git argument arrays., The HTTP fetcher requests its supplied URL and sets a package user-agent. ## Affected versions and remediation This report applies to @devflow-tools/knowledge-engine@0.18.53. - Review the evidence and your use of @devflow-tools/knowledge-engine@0.18.53 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.
