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. Source inspection found a Playwright Chromium postinstall and caller-invoked documentation fetchers using Context7 and GitHub. These behaviors do not establish malicious activity or an unresolved attack surface. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-10T16:53:03.884Z - **Finished:** 2026-10-10T16:53:51.002Z - **Download time:** 1290 ms - **Static scan time:** 353 ms - **AI review time:** 45474 ms - **Total time:** 47118 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 attack surface was identified. The postinstall hook invokes Playwright’s Chromium installer, while inspected network fetches are exported functions for retrieving documentation. - **Trigger:** Package installation invokes postinstall; documentation requests require a caller to invoke an exported fetch function. - **Impact:** The installer may download browser components, and explicit fetch calls retrieve documentation. No malicious mutation or credential exposure was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-10T16:53:51.002Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook runs the Playwright installer. The fetchers request documentation from Context7 or clone caller-selected GitHub repositories and paths. - **Rationale:** Source inspection found a Playwright Chromium postinstall and caller-invoked documentation fetchers using Context7 and GitHub. These behaviors do not establish malicious activity or an unresolved attack surface. - **Files touched:** package.json, dist/context7-fetcher.js, dist/git-fetcher.js, dist/index.js - **Network endpoints:** https://context7.com/api/v2/context, https://github.com/ ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json defines a postinstall hook that runs the Playwright Chromium installer., The exported Context7 fetcher makes requests using a fixed Context7 API and library/topic inputs., The GitHub fetcher clones a caller-specified repository and documentation paths into a caller-specified temporary directory. - **Evidence against:** The entry point exports fetch functions without invoking them during module loading., Inspected fetch paths retrieve documentation from Context7 or GitHub; no credential collection or unrelated outbound destination was identified. ## Affected versions and remediation This report applies to @devflow-tools/knowledge-engine@0.18.45. - Review the evidence and your use of @devflow-tools/knowledge-engine@0.18.45 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.
