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 inspected install hook performs ordinary Playwright Chromium setup. Network access is in retrieval functions and source inspection shows no credential harvesting, exfiltration, stealth persistence, or destructive behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-10T02:26:45.541Z - **Finished:** 2026-10-10T02:27:10.767Z - **Download time:** 779 ms - **Static scan time:** 389 ms - **AI review time:** 24057 ms - **Total time:** 25226 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 hook installs the package's Chromium browser dependency, while network retrieval functions are activated through package functionality. - **Trigger:** Package installation activates the Playwright postinstall command; GitHub and Context7 retrieval activate when their exported functionality is called. - **Impact:** No confirmed malicious effect or attack surface was established from the inspected source. - **Review source:** ai\_review - **Reviewed:** 2026-10-10T02:27:10.767Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The GitHub fetcher clones a caller-selected repository and reads Markdown files from requested paths. The Context7 fetcher sends requests to the fixed Context7 API endpoint. - **Rationale:** The inspected install hook performs ordinary Playwright Chromium setup. Network access is in retrieval functions and source inspection shows no credential harvesting, exfiltration, stealth persistence, or destructive behavior. - **Files touched:** package.json, dist/git-fetcher.js, dist/context7-fetcher.js, dist/knowledge-engine.js - **Network endpoints:** https://github.com/${repo}.git, https://context7.com/api/v2/context ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The postinstall hook runs Playwright's Chromium installer; it does not expand dependency script approvals or mutate an agent control surface., GitHub retrieval is an exported, caller-invoked function that clones a requested repository and reads Markdown files under requested documentation paths., Context7 retrieval uses a fixed Context7 API endpoint and is called through the package's retrieval functionality. ## Affected versions and remediation This report applies to @devflow-tools/knowledge-engine@0.18.23. - Review the evidence and your use of @devflow-tools/knowledge-engine@0.18.23 before allowing it.

High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts. Public source snippet (untrusted): ```json scripts.postinstall = playwright install chromium || true ``` ### 2. Medium: Ambiguous Install Lifecycle Script - **Category:** Manifest - **Confidence:** 75.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script is not statically allowlisted and needs review. Public source snippet (untrusted): ```json scripts.postinstall = playwright install chromium || true ``` ### 3. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 5. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 6. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 7. Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 8. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 70.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 9. High: Previous Version Dangerous Delta - **Category:** Supply Chain - **Confidence:** 93.0% - **Path:** dist/git-fetcher.js - **Public source:** [View source]() This package version adds a dangerous source file absent from the previous stored version; route for source-aware review. Public source snippet (untrusted): ```javascript matchType = previous_version_dangerous_delta matchedPackage = @devflow-tools/knowledge-engine@0.18.20 matchedIdentity = npm:[redacted]:0.18.20 similarity = 0.800 summary = stored previous version shares package body but lacks this dangerous source file ``` ### 10. Low: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 94.0% - **Path:** package.json - **Public source:** [View source]() The postinstall hook runs Playwright's Chromium installer; it does not expand dependency script approvals or mutate an agent control surface. Public source snippet (untrusted): ```json "postinstall": "playwright install chromium || true" }, "dependencies": { "@devflow-tools/provider-runtime": "0.18.23", "@devflow-tools/sdk": "0.18.23", "@devflow-t ``` ### 11. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** dist/git-fetcher.js - **Public source:** [View source]() GitHub retrieval is an exported, caller-invoked function that clones a requested repository and reads Markdown files under requested documentation paths. Public source snippet (untrusted): ```javascript export async function fetchFromGitHub(repo, docsPath, tmpDir) { const paths = Array.isArray(docsPath) ? docsPath : [docsPath]; const repoDir = join(tmpDir, repo.replace('/' ``` ### 12. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** dist/git-fetcher.js - **Public source:** [View source]() GitHub retrieval is an exported, caller-invoked function that clones a requested repository and reads Markdown files under requested documentation paths.
