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 routine Playwright browser install hook and user-invoked documentation fetch operations. No credential handling, stealth behavior, or concrete attack surface was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 95.0% - **Started:** 2026-10-15T18:48:35.656Z - **Finished:** 2026-10-15T18:49:14.491Z - **Download time:** 1278 ms - **Static scan time:** 366 ms - **AI review time:** 37190 ms - **Total time:** 38835 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 behavior was identified. The install hook installs the package's documented browser dependency, while exported fetch helpers retrieve documentation when called. - **Trigger:** Installation runs the postinstall hook; network and Git operations occur when a caller invokes the corresponding fetch helper. - **Impact:** No malicious effect was identified; these operations support browser-backed documentation retrieval and ingestion. - **Review source:** ai\_review - **Reviewed:** 2026-10-15T18:49:14.491Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook runs Playwright's Chromium installer. Runtime helpers fetch caller-specified URLs, Context7 documentation, or a requested GitHub repository. - **Rationale:** Source inspection found a routine Playwright browser install hook and user-invoked documentation fetch operations. No credential handling, stealth behavior, or concrete attack surface was established. - **Network endpoints:** https://context7.com/api/v2/context, https://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:** package.json defines a postinstall command that runs Playwright's Chromium installer; Playwright is a direct dependency, and the manifest has no runtime dependency on this package itself., dist/index.js re-exports library APIs and contains no startup or install logic., The Context7 fetcher retrieves documentation from context7.com when called., The GitHub helper clones a requested repository from github.com when called., The HTML fetcher accepts a URL argument and requests it when called. ## Affected versions and remediation This report applies to @devflow-tools/knowledge-engine@0.18.63. - Review the evidence and your use of @devflow-tools/knowledge-engine@0.18.63 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.
