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 lifecycle hook is package-aligned Playwright setup, not a foreign control-surface mutation. Network, filesystem, and git operations support explicit documentation sync and show no credential collection, remote code execution, or stealth persistence. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-08-26T03:39:31.202Z - **Finished:** 2026-08-26T03:40:20.591Z - **Download time:** 517 ms - **Static scan time:** 523 ms - **AI review time:** 48349 ms - **Total time:** 49389 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 malicious attack surface. The install hook only requests Playwright's Chromium asset; runtime documentation retrieval is invoked through exported KnowledgeEngine methods. - **Trigger:** npm install for Chromium setup; caller invokes KnowledgeEngine.syncDocs for retrieval. - **Impact:** Downloads a browser at install and stores fetched knowledge under the caller-selected project root. - **Evidence paths:** package.json, dist/knowledge-engine.js, dist/fetcher.js, dist/context7-fetcher.js, dist/git-fetcher.js - **Review source:** ai\_review - **Reviewed:** 2026-08-26T03:40:20.591Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Playwright browser setup and user-invoked documentation ingestion. - **Rationale:** The lifecycle hook is package-aligned Playwright setup, not a foreign control-surface mutation. Network, filesystem, and git operations support explicit documentation sync and show no credential collection, remote code execution, or stealth persistence. - **Network endpoints:** https://context7.com/api/v2/context, https://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:** Postinstall runs Playwright Chromium setup., Runtime sync fetches documentation only after explicit API use. - **Evidence against:** No credential/env harvesting or exfiltration found., No eval, VM, dynamic code loading, or shell execution beyond scoped git clone., Writes are knowledge manifests/databases under the caller project., No AI-agent control-surface mutation or persistence found. ## Affected versions and remediation This report applies to @devflow-tools/knowledge-engine@0.18.3. - Review the evidence and your use of @devflow-tools/knowledge-engine@0.18.3 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.

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]() Postinstall runs Playwright Chromium setup. Public source snippet (untrusted): ```json "postinstall": "playwright install chromium || true" ``` ### 10. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** dist/knowledge-engine.js - **Public source:** [View source]() Runtime sync fetches documentation only after explicit API use. 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, options); allResults.push(...results); ``` ## 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 0.18.3 (Dependency) - @devflow-tools/sdk 0.18.3 (Dependency) - @devflow-tools/telemetry 0.18.3 (Dependency) - playwright ^1.52.0 (Dependency) - turndown ^7.2.4 (Dependency) ## Package metadata - **Package:** @devflow-tools/knowledge-engine - **Ecosystem:** npm - **Version:** 0.18.3 - **License:** MIT - **Version published:** 2026-08-26T03:33:55.539Z - **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]()
