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 command is a standard Playwright browser installation. Inspected network and Git activity is tied to exported documentation retrieval APIs and configured sources, with no concrete attack behavior found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-17T07:12:21.335Z - **Finished:** 2026-10-17T07:15:24.448Z - **Download time:** 1025 ms - **Static scan time:** 351 ms - **AI review time:** 181736 ms - **Total time:** 183113 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 in the inspected source. The postinstall installs Playwright's Chromium browser, while network and Git operations support documentation retrieval. - **Trigger:** Package installation triggers the postinstall browser installation; runtime fetching occurs when the exported fetch or knowledge synchronization APIs are called. - **Impact:** The inspected behavior installs a browser dependency and retrieves documentation; no credential collection, unrelated data transfer, or destructive behavior was identified. - **Review source:** ai\_review - **Reviewed:** 2026-10-17T07:15:24.448Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The runtime fetcher requests its supplied URL, the Context7 helper contacts context7.com, and the GitHub helper clones the supplied repository for documentation parsing. - **Rationale:** The postinstall command is a standard Playwright browser installation. Inspected network and Git activity is tied to exported documentation retrieval APIs and configured sources, with no concrete attack behavior found. - **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:** package.json defines postinstall as Playwright's Chromium installer., The package entrypoint exports documentation-fetching utilities as runtime APIs., fetchHtml sends a caller-supplied URL through fetch; fetchHtmlKnowledgeSource invokes that flow when called., Context7 requests target the documented context API and retrieve text for configured topics., The GitHub fetcher clones a repository supplied to its exported API, and the knowledge engine calls Context7 during source synchronization. ## Affected versions and remediation This report applies to @devflow-tools/knowledge-engine@0.18.69. - Review the evidence and your use of @devflow-tools/knowledge-engine@0.18.69 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: 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:** 91.0% - **Path:** package.json - **Public source:** [View source]() package.json defines postinstall as Playwright's Chromium installer. Public source snippet (untrusted): ```json "postinstall": "playwright install chromium || true" }, "dependencies": { "@devflow-tools/provider-runtime": "0.18.69", "@devflow-tools/sd ``` ### 10. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** dist/index.js - **Public source:** [View source]() The package entrypoint exports documentation-fetching utilities as runtime APIs. Public source snippet (untrusted): ```javascript export { fetchHtml, fetchHtmlBrowser, fetchHtmlSmart, fetchHtmlKnowledgeSource, closeBrowser } from "./fetcher.js"; export { htmlToMarkdown, sliceByHeadings, extractCodeB ``` ### 11. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** dist/fetcher.js - **Public source:** [View source]() fetchHtml sends a caller-supplied URL through fetch; fetchHtmlKnowledgeSource invokes that flow when called. Public source snippet (untrusted): ```javascript export async function fetchHtml(url) { let lastError = null; for (let attempt = 0; attempt <= 2; attempt++) { try { const res = await fetch(url, { ``` ### 12. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** dist/fetcher.js - **Public source:** [View source]() fetchHtml sends a caller-supplied URL through fetch; fetchHtmlKnowledgeSource invokes that flow when called. Public source snippet (untrusted): ```javascript export async function fetchHtmlKnowledgeSource(url, options = {}) { const html = options.renderJs ? await fetchHtmlBrowser(url) : await fetchHtmlSmart(url); const markdown = htmlToMa ``` ## 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 0.18.69 (Dependency) - @devflow-tools/sdk 0.18.69 (Dependency) - @devflow-tools/telemetry 0.18.69 (Dependency) - playwright ^1.52.0 (Dependency) - turndown ^7.2.4 (Dependency) ## Package metadata - **Package:** @devflow-tools/knowledge-engine - **Ecosystem:** npm - **Version:** 0.18.69 - **License:** MIT - **Version published:** 2026-10-17T07:03:42.729Z - **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]()
