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 source confirms a Playwright browser install hook and network-capable documentation fetchers. Their inspected behavior aligns with the package’s documentation ingestion function, with no concrete attack identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-17T10:53:24.879Z - **Finished:** 2026-10-17T10:54:05.071Z - **Download time:** 780 ms - **Static scan time:** 358 ms - **AI review time:** 39054 ms - **Total time:** 40192 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 surface was identified. The inspected install hook installs the declared browser dependency, and the runtime network calls support documentation retrieval. - **Trigger:** Package installation invokes the postinstall hook; callers invoke source registration and document sync for runtime retrieval. - **Impact:** No harmful effect was established from the inspected behavior. - **Review source:** ai\_review - **Reviewed:** 2026-10-17T10:54:05.071Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook runs Playwright’s Chromium installer. Runtime code fetches registered documentation or source-configured GitHub content. - **Rationale:** The source confirms a Playwright browser install hook and network-capable documentation fetchers. Their inspected behavior aligns with the package’s documentation ingestion function, with no concrete attack identified. - **Files touched:** package.json, dist/index.js, dist/context7-fetcher.js, dist/fetcher.js, dist/knowledge-engine.js, dist/git-fetcher.js - **Network endpoints:** https://context7.com/api/v2/context, https://github.com ### 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 Playwright is a declared dependency., The package exports knowledge-engine and documentation-fetching APIs; fetching occurs through separate sync operations., Context7 requests use a fixed documentation API and topics selected for a source name., HTML retrieval fetches URLs from registered source manifests during sync., GitHub retrieval clones the repository and documentation paths supplied by the source configuration. - **Evidence against:** The inspected install hook and network calls match the package’s documentation-ingestion functionality; no concrete attack behavior was identified. ## Affected versions and remediation This report applies to @devflow-tools/knowledge-engine@0.18.73. - Review the evidence and your use of @devflow-tools/knowledge-engine@0.18.73 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.
