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 browser installation hook and network operations aligned with the package’s documentation-ingestion purpose. The runtime requests are tied to documentation sync, and no concrete attack behavior was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 95.0% - **Started:** 2026-10-17T05:48:04.206Z - **Finished:** 2026-10-17T05:48:44.230Z - **Download time:** 1542 ms - **Static scan time:** 356 ms - **AI review time:** 38125 ms - **Total time:** 40024 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 package installs a browser dependency and provides documentation retrieval and local indexing features. - **Trigger:** The postinstall hook runs during installation; documentation network requests occur when a caller invokes syncDocs. - **Impact:** The observed effects are browser setup, documentation retrieval, and local index maintenance; no malicious behavior was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-17T05:48:44.230Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The install hook requests Playwright Chromium setup. Runtime fetchers retrieve documentation from Context7, GitHub, or URLs in a source manifest; constructor cleanup targets vectors.db files in the configured knowledge directory. - **Rationale:** Source inspection found a browser installation hook and network operations aligned with the package’s documentation-ingestion purpose. The runtime requests are tied to documentation sync, and no concrete attack behavior was identified. - **Files touched:** package.json, dist/index.js, dist/knowledge-engine.js, dist/fetcher.js, dist/context7-fetcher.js, dist/git-fetcher.js, dist/types.js - **Network endpoints:** context7.com, github.com ### Review decision - **Verdict:** Clean - **Confidence:** 95.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The postinstall command installs the Playwright Chromium browser., The runtime exports KnowledgeEngine, and documentation fetching is performed by its syncDocs method., HTML retrieval uses URLs from a source manifest and converts the returned pages into documentation records., The Context7 and GitHub fetchers retrieve documentation from those services; built-in sources specify documentation repositories., Constructor cleanup removes only vectors.db files within the configured knowledge directory. ## Affected versions and remediation This report applies to @devflow-tools/knowledge-engine@0.18.68. - Review the evidence and your use of @devflow-tools/knowledge-engine@0.18.68 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.
