Installation adjusts this package’s executable bit and performs the disclosed Playwright browser setup; runtime networking and tool management are package-aligned, configured capabilities. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Clean - **Confidence:** 87.0% - **Started:** 2026-08-09T04:16:54.363Z - **Finished:** 2026-08-09T04:18:00.950Z - **Download time:** 502 ms - **Static scan time:** 1470 ms - **AI review time:** 64614 ms - **Total time:** 66587 ms ## Security analysis ### Published attack-surface review - **Summary:** No confirmed malicious attack surface. Installation adjusts this package’s executable bit and performs the disclosed Playwright browser setup; runtime networking and tool management are package-aligned, configured capabilities. - **Trigger:** npm postinstall; later explicit CLI/service or authenticated runtime use - **Impact:** Browser download/system-dependency attempt at install; runtime actions require package use and configuration. - **Evidence paths:** package.json, scripts/ensure-bin-executable.mjs, scripts/ensure-playwright-browser.mjs, dist/index.js, dist/services/auto-register.js, dist/services/tool-installer.js, dist/services/startup-config-wizard.js - **Review source:** ai\_review - **Reviewed:** 2026-08-09T04:18:00.950Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Playwright provisioning and configured runtime bridge operations - **Rationale:** The flagged primitives implement disclosed browser provisioning and a configured runtime-agent bridge. Source inspection found no concrete unconsented install-time AI-agent control-surface mutation or exfiltration chain. - **Files touched:** scripts/ensure-bin-executable.mjs, scripts/ensure-playwright-browser.mjs, dist/index.js, dist/services/auto-register.js, dist/services/tool-installer.js - **Network endpoints:** https://npmmirror.com/mirrors/playwright, http://localhost:8080 ### Review decision - **Verdict:** Clean - **Confidence:** 87.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for:** package.json postinstall runs two local scripts., scripts/ensure-playwright-browser.mjs downloads Playwright Chromium and may request OS dependencies as root., dist/services/tool-installer.js can install AI SDK/CLI tools during runtime requests. - **Evidence against:** Postinstall only chmods its own dist/index.js and invokes Playwright’s bundled CLI., Auto-registration requires configured userKey/AWS\_AUTO\_REGISTER before sending requests., Service persistence and AI-tool actions are explicit runtime CLI/API capabilities, not install-time mutations., No credential harvesting, covert endpoint, remote payload execution, or foreign AI-config mutation was confirmed. ## Public findings ### 1.
