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 postinstall hook performs browser dependency setup, while network retrieval is exposed through documentation-focused APIs and runs when callers invoke them. The inspected source showed no concrete attack behavior, credential transfer, or import-time execution. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-14T15:35:39.691Z - **Finished:** 2026-10-14T15:36:34.884Z - **Download time:** 768 ms - **Static scan time:** 338 ms - **AI review time:** 54086 ms - **Total time:** 55193 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 Playwright's Chromium browser, and the runtime network calls support documentation ingestion. - **Trigger:** Package installation runs the browser setup hook; network fetching requires a caller to invoke an exported fetch or sync API. - **Impact:** The inspected behavior supports browser-backed documentation retrieval and local knowledge storage; no concrete malicious effect was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-14T15:36:34.884Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The package installs Chromium and retrieves documentation from Context7, GitHub, or a supplied URL. Engine cleanup targets vector database files in its configured knowledge directory. - **Rationale:** The postinstall hook performs browser dependency setup, while network retrieval is exposed through documentation-focused APIs and runs when callers invoke them. The inspected source showed no concrete attack behavior, credential transfer, or import-time execution. - **Files touched:** package.json, dist/index.js, dist/context7-fetcher.js, dist/fetcher.js, dist/git-fetcher.js, dist/knowledge-engine.js - **Network endpoints:** context7.com, github.com ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The postinstall hook installs Chromium through the declared Playwright dependency., The package entrypoint exports documentation-fetching APIs; it does not invoke them during import., Context7 requests occur inside an explicit fetch function and use the Context7 documentation API., GitHub cloning occurs inside explicit documentation-fetch functions and targets documentation paths., Engine cleanup removes only vector database files under its configured knowledge directory. - **Evidence against:** Installation runs a postinstall hook that can download a browser., The exported fetch APIs can make network requests to documentation sources or caller-provided URLs. ## Affected versions and remediation This report applies to @devflow-tools/knowledge-engine@0.18.57. - Review the evidence and your use of @devflow-tools/knowledge-engine@0.18.57 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.
