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 network and child-process behavior is consistent with the package’s documentation-ingestion functions, and the postinstall command installs Chromium through Playwright. The inspected source shows no concrete attack behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-10T02:27:32.286Z - **Finished:** 2026-10-10T02:28:15.431Z - **Download time:** 1026 ms - **Static scan time:** 389 ms - **AI review time:** 41729 ms - **Total time:** 43145 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 Chromium, and the inspected fetchers retrieve documentation from their named sources. - **Trigger:** Package installation runs the postinstall hook; documentation fetches occur when source synchronization is invoked. - **Impact:** The inspected behavior installs a browser dependency and retrieves documentation; no credential theft, unrelated mutation, or malicious execution was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-10T02:28:15.431Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook invokes Playwright’s Chromium installer. The GitHub fetcher clones a requested repository and reads Markdown, while the Context7 fetcher sends documentation queries to context7.com. - **Rationale:** The flagged network and child-process behavior is consistent with the package’s documentation-ingestion functions, and the postinstall command installs Chromium through Playwright. The inspected source shows no concrete attack behavior. - **Files touched:** package.json, dist/git-fetcher.js, dist/context7-fetcher.js, dist/knowledge-engine.js - **Network endpoints:** https://github.com/${repo}.git, https://context7.com/api/v2/context ### Review decision - **Verdict:** Clean - **Confidence:** 90.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json postinstall runs Playwright’s Chromium installer., dist/git-fetcher.js clones the requested GitHub repository and checks out requested documentation paths when called., dist/knowledge-engine.js invokes fetchers as part of source synchronization; dist/context7-fetcher.js requests documentation from context7.com. - **Evidence against:** The package exports dist/index.js; its entry point exposes knowledge retrieval and source-fetching functions., The GitHub fetcher reads Markdown files and converts them into documentation chunks., The network requests target GitHub and Context7 documentation sources. ## Affected versions and remediation This report applies to @devflow-tools/knowledge-engine@0.18.36. - Review the evidence and your use of @devflow-tools/knowledge-engine@0.18.36 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.
