## Verdict summary
**Passed — safe to install** — No malicious behavior detected. 15 low-signal pattern(s) reviewed.

- **Verdict:** Clean
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Published
- **Threat category:** None published
- **Selected version:** 0.1.2
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

No confirmed malicious attack surface: the package is a user-invoked remote terminal/AI-agent controller, and the risky primitives are aligned with that purpose. Persistence and process execution are exposed as explicit runtime features rather than install-time behavior.

## Security analysis

### Published attack-surface review

- **Summary:** No confirmed malicious attack surface: the package is a user-invoked remote terminal/AI-agent controller, and the risky primitives are aligned with that purpose. Persistence and process execution are exposed as explicit runtime features rather than install-time behavior.

- **Trigger:** User runs \`reins\` or \`reins service install\`.

- **Impact:** Intended remote operation of local shell/AI agent after pairing; no stealth install-time compromise found.

- **Evidence paths:** package.json, dist/cli.mjs

- **Review source:** ai\_review

- **Reviewed:** 2026-07-01T06:50:17.796Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Authenticated WebSocket relay/local mobile control of PTY and AI CLI processes.

- **Rationale:** The package contains powerful remote-control, PTY, SSH, and persistence capabilities, but they are consistent with the declared CLI product and are not activated by npm lifecycle or import-time execution. I found no credential harvesting/exfiltration, hidden payload execution, or unconsented AI-agent control mutation.

- **Files touched:** ~/.ai\_remote\_vibe\_agent/headless-store.json, ~/.ai\_remote\_vibe\_agent/session-token.txt, ~/.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://arv.juny-api.kr/updates, ws://0.0.0.0:3001/mobile

### Review decision

- **Verdict:** Clean

- **Confidence:** 86.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Medium

- **Evidence for:** dist/cli.mjs opens local WS on 0.0.0.0 and relay client to wss://juny-api.kr/relay or wss://relay.juny-api.kr/relay., dist/cli.mjs can spawn PTYs and allowed AI CLIs (claude/codex/gemini) from authenticated mobile messages., dist/cli.mjs has user-invoked service install code writing launchd/systemd/schtasks persistence files.

- **Evidence against:** package.json has no install/preinstall/postinstall lifecycle hooks; bin is user-invoked dist/cli.mjs., Remote control behavior matches README/package description: phone-controlled headless AI coding agent., Local/relay mobile channels use a generated session token/HMAC before accepting control messages., Service persistence is only reached via \`reins service install\`, not on install/import., No remote asset decode/execute pattern found; update feed only fetches installer metadata for UI.
