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 lifecycle hook performs ordinary Playwright browser setup, while the inspected network behavior is tied to documentation retrieval from a fixed service. These source facts do not establish malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-14T15:37:57.475Z - **Finished:** 2026-10-14T15:42:23.133Z - **Download time:** 1276 ms - **Static scan time:** 356 ms - **AI review time:** 264025 ms - **Total time:** 265658 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 Chromium, and inspected runtime network calls support the package’s documentation-ingestion function. - **Trigger:** Package installation runs the postinstall hook; runtime fetching occurs when the relevant documentation source is synchronized. - **Impact:** The inspected behavior installs a browser and retrieves documentation; it does not establish credential disclosure, unauthorized account actions, or malicious system changes. - **Review source:** ai\_review - **Reviewed:** 2026-10-14T15:42:23.133Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook invokes Playwright’s Chromium installer. Runtime code retrieves documentation from the fixed Context7 endpoint using configured source identifiers. - **Rationale:** The flagged lifecycle hook performs ordinary Playwright browser setup, while the inspected network behavior is tied to documentation retrieval from a fixed service. These source facts do not establish malicious behavior. - **Network endpoints:** https://context7.com/api/v2/context ### Review decision - **Verdict:** Clean - **Confidence:** 96.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The postinstall hook runs Playwright’s Chromium installer and ignores its failure., The package exports documentation fetchers as part of its runtime API., The Context7 fetcher sends requests to the fixed Context7 API endpoint., The engine calls the Context7 fetcher with a configured source; the built-in React source points to its documentation repository. ## Affected versions and remediation This report applies to @devflow-tools/knowledge-engine@0.18.58. - Review the evidence and your use of @devflow-tools/knowledge-engine@0.18.58 before allowing it.
