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 is an undesirable automatic browser download, but it is package-aligned with the declared Playwright dependency and browser fetcher. Static inspection found no concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-08T02:02:57.090Z - **Finished:** 2026-09-08T02:03:39.920Z - **Download time:** 503 ms - **Static scan time:** 643 ms - **AI review time:** 41684 ms - **Total time:** 42830 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 confirmed malicious attack surface was established. Installation downloads a Playwright browser dependency, while runtime network and Git operations are documentation-ingestion features invoked by exported functions. - **Trigger:** Package installation downloads Chromium; callers must invoke exported ingestion functions for network or Git activity. - **Impact:** No credential collection, secret exfiltration, persistence, destructive action, or AI-agent control-surface mutation was found. - **Review source:** ai\_review - **Reviewed:** 2026-09-08T02:03:39.920Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Playwright browser provisioning and caller-invoked documentation retrieval. - **Rationale:** The postinstall is an undesirable automatic browser download, but it is package-aligned with the declared Playwright dependency and browser fetcher. Static inspection found no concrete malicious behavior. ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** Its automatic postinstall invokes Playwright's Chromium installer and ignores failures., The runtime can fetch Context7 documentation over HTTPS. - **Evidence against:** Chromium is a declared dependency and is used only by the exported browser-based HTML fetcher., Network fetches are in exported, caller-invoked documentation-ingestion functions; no install-time package source performs credential harvesting or exfiltration., Git execution is an explicit, argument-vector sparse clone of a caller-supplied documentation repository, not shell execution. ## Affected versions and remediation This report applies to @devflow-tools/knowledge-engine@0.18.13. - Review the evidence and your use of @devflow-tools/knowledge-engine@0.18.13 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.
