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 standard Playwright browser setup hook and documentation retrieval that runs through an explicit runtime API against public documentation sources. No concrete attack behavior was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-17T09:25:43.358Z - **Finished:** 2026-10-17T09:26:16.658Z - **Download time:** 1529 ms - **Static scan time:** 361 ms - **AI review time:** 31410 ms - **Total time:** 33300 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 install hook sets up the Playwright browser, while documentation retrieval is exposed through an explicitly called sync API. - **Trigger:** Package installation triggers the Playwright Chromium setup; documentation retrieval requires calling syncDocs. - **Impact:** No source evidence indicates credential collection, unrelated data disclosure, or harmful system changes. - **Review source:** ai\_review - **Reviewed:** 2026-10-17T09:26:16.658Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The sync API retrieves documentation from configured public sources and can clone their documentation repositories. - **Rationale:** Source inspection found a standard Playwright browser setup hook and documentation retrieval that runs through an explicit runtime API against public documentation sources. No concrete attack behavior was identified. - **Network endpoints:** context7.com, github.com ### 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 installs Chromium through Playwright; it does not run the package’s documentation sync code., Documentation network access is inside the exported syncDocs method and starts when that method is called., Built-in sources point to public framework documentation repositories and documentation hosts., GitHub cloning occurs in the fetcher invoked by documentation sync. ## Affected versions and remediation This report applies to @devflow-tools/knowledge-engine@0.18.71. - Review the evidence and your use of @devflow-tools/knowledge-engine@0.18.71 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. 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. Low: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 94.0% - **Path:** package.json - **Public source:** [View source]() The postinstall hook installs Chromium through Playwright; it does not run the package’s documentation sync code. Public source snippet (untrusted): ```json "scripts": { "build": "tsc -b", "test": "node ../../node_modules/.bin/vitest run", "typecheck": "tsc --noEmit", "clean": "rm -rf dist", "postinstall": "playwright install chromium || true" }, "dependencies": { ``` ### 10. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** dist/knowledge-engine.js - **Public source:** [View source]() Documentation network access is inside the exported syncDocs method and starts when that method is called. Public source snippet (untrusted): ```javascript async syncDocs(pluginName, options = {}) { const name = pluginName ?? ""; // Sync all: iterate all registered knowledge sources if (!name) { const allResults = []; if (!existsSync(this.knowledgeDir)) return []; const dirs = readdirSync(this.knowledgeDir, { withFileTypes: true }) .filter(d => d.isDirectory()) .map(d => d.name); for (const dirName of dirs) { const results = await this.syncDocs(dirName, option ``` ### 11. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** dist/types.js - **Public source:** [View source]() Built-in sources point to public framework documentation repositories and documentation hosts. Public source snippet (untrusted): ```javascript export const BUILTIN_SOURCES = [ { name: "react", context7Id: "/reactjs/react.dev", githubRepo: "reactjs/react.dev", githubDocsPath: "src/content/reference/react", l3Urls: ["https://react.dev/reference/react/hooks"], version: "19", }, { name: "vue", context7Id: "/vuejs/docs", githubRepo: " ``` ### 12. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** dist/git-fetcher.js - **Public source:** [View source]() GitHub cloning occurs in the fetcher invoked by documentation sync. Public source snippet (untrusted): ```javascript } } return results; } export async function fetchFromGitHub(repo, docsPath, tmpDir) { const paths = Array.isArray(docsPath) ? docsPath : [docsPath]; const repoDir = join(tmpDir, repo.replace('/', '_')); if (!existsSync(repoDir)) { mkdirSync(tmpDir, { recursive: true }); try { ``` ## 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 0.18.71 (Dependency) - @devflow-tools/sdk 0.18.71 (Dependency) - @devflow-tools/telemetry 0.18.71 (Dependency) - playwright ^1.52.0 (Dependency) - turndown ^7.2.4 (Dependency) ## Package metadata - **Package:** @devflow-tools/knowledge-engine - **Ecosystem:** npm - **Version:** 0.18.71 - **License:** MIT - **Version published:** 2026-10-17T09:07:36.720Z - **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:** 695,869 bytes - **Artifact signatures:** 2 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
