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 lifecycle hook is an unconditional but package-aligned Playwright browser installation, and the remaining network and subprocess behavior supports explicit documentation ingestion. No concrete malicious behavior or prohibited control-surface mutation was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-13T00:25:09.713Z - **Finished:** 2026-09-13T00:25:50.272Z - **Download time:** 1012 ms - **Static scan time:** 400 ms - **AI review time:** 39146 ms - **Total time:** 40559 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. The package installs a Playwright browser and provides user-invoked documentation retrieval helpers. - **Trigger:** Package installation invokes Playwright; callers must invoke exported retrieval helpers for network and git activity. - **Impact:** Downloads a Chromium browser at install time; invoked helpers can retrieve configured public documentation. - **Review source:** ai\_review - **Reviewed:** 2026-09-13T00:25:50.272Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Browser dependency setup and documentation ingestion. - **Rationale:** The lifecycle hook is an unconditional but package-aligned Playwright browser installation, and the remaining network and subprocess behavior supports explicit documentation ingestion. No concrete malicious behavior or prohibited control-surface mutation was found. ### Review decision - **Verdict:** Clean - **Confidence:** 88.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The install hook invokes Playwright's Chromium installer., An exported helper runs git clone to retrieve configured documentation., The Context7 helper fetches documentation from context7.com. - **Evidence against:** The install hook is limited to a standard Playwright browser download; it does not modify agent configuration or project source., Network and git operations are explicit exported documentation-ingestion functions, not import-time execution., No credential harvesting, secret exfiltration, self-dependency, obfuscation, or destructive project mutation was found. ## Affected versions and remediation This report applies to @devflow-tools/knowledge-engine@0.18.18. - Review the evidence and your use of @devflow-tools/knowledge-engine@0.18.18 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.
