Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The package provides a real remote-control capability and persistence, so it warrants a warning. Source inspection ties these actions to explicit agent use and a guarded global migration path, not a covert install-time attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-03T15:51:47.297Z - **Finished:** 2026-09-03T15:53:13.912Z - **Download time:** 1011 ms - **Static scan time:** 4151 ms - **AI review time:** 81452 ms - **Total time:** 86615 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:** This is a remote-development agent with a relay-controlled terminal and filesystem workflow. A user-started agent can persist as a user service by default. - **Trigger:** Run agentlink-client start and connect it to a relay. - **Impact:** A trusted or compromised relay can execute shell input and access or modify local user data through the running agent. - **Evidence paths:** dist/connection.js, dist/terminal.js, dist/auto-start.js, scripts/install-bridge.cjs, dist/runtime-release.js - **Review source:** ai\_review - **Reviewed:** 2026-09-03T15:53:13.912Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** WebSocket-controlled shell, file operations, and user-level auto-start. - **Rationale:** The package provides a real remote-control capability and persistence, so it warrants a warning. Source inspection ties these actions to explicit agent use and a guarded global migration path, not a covert install-time attack. - **Files touched:** ~/.agentlink/config.json, ~/.config/systemd/user/agentlink.service, ~/Library/LaunchAgents/com.agentlink.agent.plist - **Network endpoints:** wss://msclaude.ai, https://msclaude.ai ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The package opens a WebSocket to its configured relay and dispatches received messages., Relay messages can open a shell and pass arbitrary terminal input to it., Starting the agent enables user-level auto-start by default after a healthy run., Global postinstall invokes a bridge that can fetch and stage a replacement runtime from msclaude.ai. - **Evidence against:** The install hook runs only for global npm installs and the bridge proceeds only after an existing completed adoption state., The exposed remote-control and persistence functions are tied to the package's stated local-agent workflow; no covert credential harvesting or unrelated exfiltration was found. ## Affected versions and remediation This report applies to @agent-link/agent@0.1.335. - Review the evidence and your use of @agent-link/agent@0.1.335 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.
