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 hook installs Chromium for the package’s Playwright-backed documentation fetcher. Inspected network and Git operations support documentation retrieval through library APIs, with no concrete attack behavior identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 97.0% - **Started:** 2026-10-14T15:33:34.443Z - **Finished:** 2026-10-14T15:34:25.757Z - **Download time:** 760 ms - **Static scan time:** 357 ms - **AI review time:** 50196 ms - **Total time:** 51314 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. The postinstall command installs the browser runtime used by the package’s browser-fetching API, while documentation network access is part of explicit library operations. - **Trigger:** Package installation triggers the Chromium installer; callers trigger document retrieval by invoking the relevant library APIs. - **Impact:** No malicious mutation, credential exposure, or other concrete attack effect was found in the inspected source. - **Review source:** ai\_review - **Reviewed:** 2026-10-14T15:34:25.757Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The package installs Playwright Chromium and retrieves documentation from Context7, GitHub, or a caller-supplied URL for processing. - **Rationale:** The postinstall hook installs Chromium for the package’s Playwright-backed documentation fetcher. Inspected network and Git operations support documentation retrieval through library APIs, with no concrete attack behavior identified. - **Network endpoints:** https://context7.com/api/v2/context, https://github.com/${repo}.git ### Review decision - **Verdict:** Clean - **Confidence:** 97.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json defines postinstall as installing Playwright Chromium, matching the runtime’s Playwright browser support., The package entrypoint exports library APIs; its documentation retrieval runs through syncDocs when called and when a source is registered., The Context7 fetcher requests documentation topics from the Context7 API; the GitHub fetcher clones documentation repositories into its supplied temporary directory., HTML retrieval fetches the URL supplied to the library and converts the response to Markdown. ## Affected versions and remediation This report applies to @devflow-tools/knowledge-engine@0.18.50. - Review the evidence and your use of @devflow-tools/knowledge-engine@0.18.50 before allowing it.
