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-time command is a Playwright browser setup step. Inspected runtime network and Git operations retrieve documentation through exposed APIs and the syncDocs flow; no concrete malicious behavior was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-14T15:34:41.911Z - **Finished:** 2026-10-14T15:35:32.256Z - **Download time:** 1293 ms - **Static scan time:** 360 ms - **AI review time:** 48691 ms - **Total time:** 50345 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 Chromium for Playwright, and inspected network operations support documentation fetching. - **Trigger:** Package installation triggers the Playwright installer; documentation network requests occur when runtime sync or fetch APIs are invoked. - **Impact:** No malicious effect or unauthorized data transfer was established from the inspected source. - **Review source:** ai\_review - **Reviewed:** 2026-10-14T15:35:32.256Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook runs the Chromium installer. Runtime code retrieves documentation from Context7, GitHub, or a URL supplied to a fetch API. - **Rationale:** The install-time command is a Playwright browser setup step. Inspected runtime network and Git operations retrieve documentation through exposed APIs and the syncDocs flow; no concrete malicious behavior was found. - **Files touched:** package.json, dist/index.js, dist/knowledge-engine.js, dist/context7-fetcher.js, dist/git-fetcher.js, dist/fetcher.js - **Network endpoints:** https://context7.com/api/v2/context, https://github.com/${repo}.git ### 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 invokes Playwright's Chromium installer., The package exposes fetching through runtime APIs, and documentation sync is performed by syncDocs., The Context7 code fetches documentation text from its declared API endpoint., GitHub cloning occurs through the documentation sync flow for configured repositories. ## Affected versions and remediation This report applies to @devflow-tools/knowledge-engine@0.18.52. - Review the evidence and your use of @devflow-tools/knowledge-engine@0.18.52 before allowing it.
