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 invokes Playwright's Chromium installer, while the exported runtime APIs fetch documentation when called. Inspected source showed no concrete attack behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-15T18:48:24.070Z - **Finished:** 2026-10-15T18:49:07.658Z - **Download time:** 518 ms - **Static scan time:** 362 ms - **AI review time:** 42708 ms - **Total time:** 43588 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, and runtime network access supports documentation retrieval. - **Trigger:** The Chromium installer runs during package installation; documentation requests require a caller to invoke the runtime sync API. - **Impact:** The inspected behavior supports browser setup and knowledge ingestion; it does not establish credential disclosure or harmful mutation. - **Review source:** ai\_review - **Reviewed:** 2026-10-15T18:49:07.658Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook runs Playwright's Chromium installer. Runtime code retrieves public documentation from Context7, GitHub, or configured URLs. - **Rationale:** The postinstall hook invokes Playwright's Chromium installer, while the exported runtime APIs fetch documentation when called. Inspected source showed no concrete attack behavior. - **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:** package.json runs Playwright's Chromium installer at postinstall., The entrypoint exports the knowledge engine API; its syncDocs operation is an explicit runtime method., Built-in source syncing retrieves documentation from Context7 and GitHub., HTML fetching uses a supplied URL and sends only a User-Agent header., GitHub fetching clones documentation repositories with git argument arrays. ## Affected versions and remediation This report applies to @devflow-tools/knowledge-engine@0.18.61. - Review the evidence and your use of @devflow-tools/knowledge-engine@0.18.61 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.
