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. Source inspection found a conventional Playwright browser installation hook and documentation retrieval functions. The scanner's network and lifecycle signals correspond to those package functions, with no concrete attack behavior identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-10T02:27:16.313Z - **Finished:** 2026-10-10T02:27:46.144Z - **Download time:** 1023 ms - **Static scan time:** 358 ms - **AI review time:** 28449 ms - **Total time:** 29831 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 installs the Chromium browser used by Playwright, and the inspected fetchers retrieve documentation. - **Trigger:** Package installation activates the postinstall hook; documentation fetch functions run when called by a consumer. - **Impact:** No harmful effect was established in the inspected source; the observed behavior supports browser setup and documentation ingestion. - **Review source:** ai\_review - **Reviewed:** 2026-10-10T02:27:46.144Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook invokes Playwright's Chromium installer. Fetchers clone requested GitHub repositories or request documentation from Context7. - **Rationale:** Source inspection found a conventional Playwright browser installation hook and documentation retrieval functions. The scanner's network and lifecycle signals correspond to those package functions, with no concrete attack behavior identified. - **Files touched:** package.json, dist/git-fetcher.js, dist/context7-fetcher.js - **Network endpoints:** https://github.com/${repo}.git, https://context7.com/api/v2/context ### 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 hook invokes Playwright's Chromium installer., The GitHub fetcher clones a caller-specified repository and reads Markdown files from requested paths., The Context7 fetcher retrieves documentation text from context7.com. - **Evidence against:** The inspected lifecycle hook contains no consumer policy or agent configuration write., The inspected network and Git operations serve documentation retrieval. ## Affected versions and remediation This report applies to @devflow-tools/knowledge-engine@0.18.27. - Review the evidence and your use of @devflow-tools/knowledge-engine@0.18.27 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.
