Installation performs package-aligned CLI permission setup and optional Playwright browser provisioning; service and AI-config features are runtime or explicit-command actions. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Clean - **Confidence:** 92.0% - **Started:** 2026-08-09T15:03:50.570Z - **Finished:** 2026-08-09T15:04:58.729Z - **Download time:** 754 ms - **Static scan time:** 2107 ms - **AI review time:** 65297 ms - **Total time:** 68159 ms ## Security analysis ### Published attack-surface review - **Summary:** No confirmed malicious attack surface. Installation performs package-aligned CLI permission setup and optional Playwright browser provisioning; service and AI-config features are runtime or explicit-command actions. - **Trigger:** npm postinstall; later explicit CLI or authenticated runtime use - **Impact:** Installs Chromium dependencies when enabled; no unconsented foreign AI-agent control-surface mutation found. - **Evidence paths:** package.json, scripts/ensure-bin-executable.mjs, scripts/ensure-playwright-browser.mjs, dist/services/cli-commands.js, dist/middleware/auth.js, dist/services/auto-register.js - **Review source:** ai\_review - **Reviewed:** 2026-08-09T15:04:58.729Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Playwright provisioning and authenticated runtime bridge operations - **Rationale:** The suspicious primitives implement the declared runtime-bridge functionality and are gated by install, explicit CLI commands, configuration, or authentication. Source inspection found no credential harvesting, covert exfiltration, remote payload execution, or unconsented AI-agent configuration mutation. - **Files touched:** dist/index.js - **Network endpoints:** https://npmmirror.com/mirrors/playwright ### Review decision - **Verdict:** Clean - **Confidence:** 92.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall., scripts/ensure-playwright-browser.mjs downloads Playwright Chromium; root Linux path requests --with-deps., dist/services/cli-commands.js can create system services, but only for explicit \`awsb service install\`. - **Evidence against:** Postinstall only chmods dist/index.js and invokes the bundled Playwright CLI., No lifecycle script writes Claude, Codex, OpenCode, or Acode configuration., dist/middleware/auth.js requires a runtime token for protected routes; unpaired requests are rejected., dist/services/auto-register.js only contacts a scheduler configured through user config or environment. ## Public findings ### 1.
