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. Inspected source shows a conventional Playwright browser installation hook and explicit documentation-fetching APIs. No concrete malicious behavior was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-10T02:27:05.013Z - **Finished:** 2026-10-10T02:27:34.946Z - **Download time:** 1011 ms - **Static scan time:** 408 ms - **AI review time:** 28514 ms - **Total time:** 29933 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 in the inspected lifecycle and fetcher behavior. The package installs Chromium through Playwright and provides explicit documentation-fetching APIs. - **Trigger:** Package installation triggers the postinstall command; consumers invoke the exported fetching APIs to retrieve documentation. - **Impact:** These actions install a browser dependency and retrieve requested documentation; no harmful effect was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-10T02:27:34.946Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall runs Playwright’s Chromium installer. The GitHub fetcher clones the supplied repository into a temporary directory, while the Context7 fetcher requests documentation from Context7. - **Rationale:** Inspected source shows a conventional Playwright browser installation hook and explicit documentation-fetching APIs. No concrete malicious behavior was established. - **Files touched:** package.json, dist/git-fetcher.js, dist/context7-fetcher.js, dist/index.js - **Network endpoints:** https://context7.com/api/v2/context, https://github.com/${repo}.git ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The postinstall command runs Playwright’s Chromium installer., GitHub fetching is exposed as a function that accepts repository, documentation path, and temporary directory arguments., The package exports its Context7 and GitHub fetch functions as APIs. - **Evidence against:** No inspected source showed credential harvesting, policy mutation, or covert network transmission., The Context7 fetcher uses the Context7 API to retrieve documentation. ## Affected versions and remediation This report applies to @devflow-tools/knowledge-engine@0.18.24. - Review the evidence and your use of @devflow-tools/knowledge-engine@0.18.24 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.
