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 install hook installs Chromium, which the package uses for browser-based documentation fetching. Inspected network and Git operations are tied to documentation sync, and no concrete attack behavior was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 93.0% - **Started:** 2026-10-16T05:26:52.993Z - **Finished:** 2026-10-16T05:27:37.159Z - **Download time:** 1005 ms - **Static scan time:** 364 ms - **AI review time:** 42797 ms - **Total time:** 44166 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 install hook sets up the browser used for documentation fetching, and runtime network access is part of the exported sync functionality. - **Trigger:** Package installation runs the Playwright browser setup; documentation requests occur when the sync API is called. - **Impact:** The inspected behavior supports documentation ingestion and browser setup; no harmful effect was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-16T05:27:37.159Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The sync API fetches configured documentation URLs and built-in sources, and can clone a specified GitHub documentation repository. - **Rationale:** The install hook installs Chromium, which the package uses for browser-based documentation fetching. Inspected network and Git operations are tied to documentation sync, and no concrete attack behavior was found. ### Review decision - **Verdict:** Clean - **Confidence:** 93.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The postinstall command installs Playwright’s Chromium browser; the runtime uses headless Chromium for browser-based fetching., The package exports KnowledgeEngine and its documentation fetch helpers through its main entrypoint., Documentation network requests run through syncDocs, using configured manifest URLs or built-in documentation sources., The HTTP fetcher retrieves the requested documentation URL, while Context7 requests use the fixed context7.com API endpoint., The Git helper invokes git with an argument array to clone the specified GitHub repository; no shell command is constructed. ## Affected versions and remediation This report applies to @devflow-tools/knowledge-engine@0.18.64. - Review the evidence and your use of @devflow-tools/knowledge-engine@0.18.64 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.
