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 explains the lifecycle hook and flagged Git helper as ordinary Playwright setup and documentation retrieval. No concrete attack behavior was found, so the scanner signals do not support a warning or block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-10T02:26:57.074Z - **Finished:** 2026-10-10T02:27:30.611Z - **Download time:** 1284 ms - **Static scan time:** 342 ms - **AI review time:** 31910 ms - **Total time:** 33537 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 malicious attack surface was identified in the inspected files. Network and Git operations support retrieving documentation for the knowledge engine. - **Trigger:** The postinstall hook runs when the package is installed; documentation retrieval occurs when the engine synchronizes sources. - **Impact:** The inspected behavior installs a browser dependency and imports public documentation into the knowledge store; no harmful effect was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-10T02:27:30.611Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook invokes Playwright's Chromium installer. Sync code fetches configured HTML sources and documentation from Context7 or GitHub. - **Rationale:** Inspected source explains the lifecycle hook and flagged Git helper as ordinary Playwright setup and documentation retrieval. No concrete attack behavior was found, so the scanner signals do not support a warning or block. - **Files touched:** package.json, dist/git-fetcher.js, dist/knowledge-engine.js, dist/context7-fetcher.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 installs Chromium through Playwright, a conventional browser setup step., Git documentation retrieval is implemented as an explicit repository and path based fetcher., The engine calls the GitHub and Context7 fetchers for built-in sources during document sync., HTML retrieval uses URLs in the source manifest and stores fetched content as documentation. - **Evidence against:** No inspected source showed credential harvesting, unrelated endpoint forwarding, stealth persistence, destructive behavior, or hidden payload execution., The flagged Git helper clones a caller-selected GitHub repository and reads Markdown files; its command arguments are passed separately to git., Network requests are directed to Context7, GitHub documentation repositories, or manifest-provided documentation URLs. ## Affected versions and remediation This report applies to @devflow-tools/knowledge-engine@0.18.0. - Review the evidence and your use of @devflow-tools/knowledge-engine@0.18.0 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. 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.

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 = 0.767 summary = stored previous version shares package body but lacks this dangerous source file ``` ### 10. Low: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 91.0% - **Path:** package.json - **Public source:** [View source]() The postinstall command installs Chromium through Playwright, a conventional browser setup step. Public source snippet (untrusted): ```json "postinstall": "playwright install chromium || true" }, "dependencies": { "@devflow-tools/provider-runtime": "0.18.0", "@devflow-tools/sdk": "0. ``` ### 11. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** dist/git-fetcher.js - **Public source:** [View source]() Git documentation retrieval is implemented as an explicit repository and path based fetcher. 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:** 91.0% - **Path:** dist/knowledge-engine.js - **Public source:** [View source]() The engine calls the GitHub and Context7 fetchers for built-in sources during document sync. Public source snippet (untrusted): ```javascript c7Result = await fetchFromContext7(sourceConfig.context7Id, sourceConfig.name); } catch (err) { emitSemanticControlLog({ ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall - **Dependencies:** 5 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 3 - **Published dependency-graph edges:** 5 ### Published dependency entries - @devflow-tools/provider-runtime 0.18.0 (Dependency) - @devflow-tools/sdk 0.18.0 (Dependency) - @devflow-tools/telemetry 0.18.0 (Dependency) - playwright ^1.52.0 (Dependency) - turndown ^7.2.4 (Dependency) ## Package metadata - **Package:** @devflow-tools/knowledge-engine - **Ecosystem:** npm - **Version:** 0.18.0 - **License:** MIT - **Version published:** 2026-08-24T08:57:01.526Z - **Package first seen:** 2026-07-02T12:10:46.773Z - **Package last seen:** 2026-11-03T02:54:45.706Z - **Known versions:** 65 - **Latest version:** 0.19.3 - **Appeal under review:** No - **Description:** Version-aware project knowledge ingestion and retrieval for DevFlow. - **Maintainers:** shilongfei - **Artifact files:** 119 - **Artifact unpacked size:** 674,437 bytes - **Artifact signatures:** 2 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
