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 is browser setup, while the inspected runtime network and git operations serve the package’s documentation ingestion APIs. No concrete attack behavior was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 97.0% - **Started:** 2026-10-17T09:41:50.043Z - **Finished:** 2026-10-17T09:42:20.466Z - **Download time:** 1542 ms - **Static scan time:** 352 ms - **AI review time:** 28529 ms - **Total time:** 30423 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 inspected network and subprocess behavior supports documentation ingestion, and the install hook installs the browser used by the exported fetcher. - **Trigger:** Package installation runs the postinstall hook; documentation requests occur when the sync or fetch APIs are invoked. - **Impact:** These behaviors install a browser and retrieve documentation; inspected source does not show credential collection, unrelated data transfer, or harmful system changes. - **Review source:** ai\_review - **Reviewed:** 2026-10-17T09:42:20.466Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook invokes Playwright’s Chromium installer. Runtime fetchers retrieve documentation from Context7, GitHub, or a supplied URL; the GitHub fetcher uses git to clone the configured repository. - **Rationale:** The postinstall hook is browser setup, while the inspected runtime network and git operations serve the package’s documentation ingestion APIs. No concrete attack behavior was found. - **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:** The postinstall command installs Chromium for the package’s Playwright browser support., The package exports documentation fetchers, and its Context7 requests target the Context7 API., The GitHub fetcher clones the configured repository and documentation sync calls it for built-in sources. - **Evidence against:** The package has a postinstall hook and runtime network and subprocess operations; inspected source ties these to browser setup and documentation retrieval. ## Affected versions and remediation This report applies to @devflow-tools/knowledge-engine@0.18.72. - Review the evidence and your use of @devflow-tools/knowledge-engine@0.18.72 before allowing it.
