The package is a user-invoked remote terminal/AI-agent control CLI with explicit relay and optional service features matching its README. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Clean - **Confidence:** 88.0% - **Started:** 2026-07-06T04:09:54.872Z - **Finished:** 2026-07-06T04:10:40.665Z - **Download time:** 520 ms - **Static scan time:** 940 ms - **AI review time:** 44332 ms - **Total time:** 45793 ms ## Security analysis ### Published attack-surface review - **Summary:** No confirmed malicious attack surface was established. The package is a user-invoked remote terminal/AI-agent control CLI with explicit relay and optional service features matching its README. - **Trigger:** User runs \`reins\` or explicit \`reins service install\` - **Impact:** Remote paired client can interact with configured local/SSH terminals as advertised; no unconsented install-time behavior found. - **Evidence paths:** package.json, README.md, dist/cli.mjs - **Review source:** ai\_review - **Reviewed:** 2026-07-06T04:10:40.665Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** WebSocket relay/local server, PTY/SSH terminal forwarding, explicit service registration - **Rationale:** The high-risk primitives are consistent with the documented purpose of a remote terminal/agent viewer and are activated by user runtime commands, not npm lifecycle hooks. Static inspection did not find stealth payload execution, exfiltration, destructive behavior, or unconsented AI-agent control-surface mutation. - **Files touched:** ~/.ai\_remote\_vibe\_agent/headless-store.json, ~/.ai\_remote\_vibe\_agent/session-token.txt, ~/.ai\_remote\_vibe\_agent/logs, ~/.claude\_code\_agent/machines.json, ~/.claude\_code\_agent/keyring.key, ~/Library/LaunchAgents/com.junyoung-kim.reins.plist, ~/.config/systemd/user/reins.service, ~/.ai\_remote\_vibe\_agent/reins-service.cmd - **Network endpoints:** wss://juny-api.kr/relay, https://arv.juny-api.kr, wss://relay.juny-api.kr/relay, https://registry.npmjs.org/@junyoung-kim%2Freins/latest, https://arv.juny-api.kr/updates ### Review decision - **Verdict:** Clean - **Confidence:** 88.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Medium - **Evidence against:** package.json has no preinstall/install/postinstall hooks; bin is user-invoked dist/cli.mjs, README.md clearly describes remote terminal mirroring via phone, relay, QR pairing, service install, and config files, dist/cli.mjs relay/local WebSocket behavior is package-aligned and gated by runtime pairing/session token, dist/cli.mjs service persistence is explicit via \`reins service install\` or TUI action, not install-time mutation, dist/cli.mjs child\_process/node-pty usage runs user terminals or allowed agents (claude/codex/gemini) for the advertised remote-control feature, No decoded remote asset execution, credential harvesting, or hidden lifecycle execution found in inspected source ## Public findings ### 1.
