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 does not perform the agent configuration mutation during postinstall; that script only changes node-pty helper permissions. However, its default start workflow writes shared AI-agent hooks and handles permission events, creating a real user-invoked control-surface risk. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-12T16:33:54.444Z - **Finished:** 2026-09-12T16:34:57.076Z - **Download time:** 763 ms - **Static scan time:** 2083 ms - **AI review time:** 59785 ms - **Total time:** 62632 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:** An explicit linkshell start session modifies shared AI-agent hook configuration and receives tool-event data over loopback. This can affect Claude, Codex, Gemini, and a project hook file while the bridge runs. - **Trigger:** The user runs linkshell start, which enables the agent workspace by default. - **Impact:** A remote-terminal bridge gains visibility into agent activity and can mediate permission-hook responses during the active session. - **Evidence paths:** src/index.ts, src/runtime/bridge-session.ts, src/runtime/hook-command.ts - **Review source:** ai\_review - **Reviewed:** 2026-09-12T16:34:57.076Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Installs temporary command hooks that forward agent events to a local HTTP server. - **Rationale:** The package does not perform the agent configuration mutation during postinstall; that script only changes node-pty helper permissions. However, its default start workflow writes shared AI-agent hooks and handles permission events, creating a real user-invoked control-surface risk. - **Files touched:** ~/.claude/settings.json, ~/.codex/config.toml, ~/.codex/hooks.json, ~/.gemini/settings.json, hooks.json - **Network endpoints:** 127.0.0.1 ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The user-invoked start command enables an agent workspace by default., Starting a terminal installs hooks for Claude, Codex, Gemini, and Copilot., The Claude hook setup adds a PermissionRequest hook and writes the shared settings file., Generated hooks send agent event data to a local LinkShell HTTP server. - **Evidence against:** The install-time script only repairs execute permissions on node-pty helper binaries., Hook configuration is reached from the explicit start command, not from postinstall., The hook command targets loopback only; no secret-exfiltration endpoint was found in this path. ## Affected versions and remediation This report applies to linkshell-cli@0.5.37. - Review the evidence and your use of linkshell-cli@0.5.37 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.
