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. Source confirms broad AI-agent hook mutation and remote relay, but only behind the documented user-invoked bridge command. The install hook is limited to node-pty helper permissions. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 95.0% - **Started:** 2026-08-04T08:33:46.940Z - **Finished:** 2026-08-04T08:34:28.826Z - **Download time:** 774 ms - **Static scan time:** 1855 ms - **AI review time:** 39256 ms - **Total time:** 41886 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 bridge start can add hook commands to several AI-agent configurations, including Codex feature enablement. The bridge then relays terminal and hook-derived status through its configured gateway. - **Trigger:** User runs \`linkshell start\`, particularly with the default custom provider. - **Impact:** A paired remote client can observe/control the started terminal session and receive agent lifecycle or permission-related events. - **Evidence paths:** package.json, scripts/postinstall.mjs, src/index.ts, dist/cli/src/runtime/bridge-session.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T08:34:28.826Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Runtime AI-agent hook installation plus remote terminal/WebSocket relay. - **Rationale:** Source confirms broad AI-agent hook mutation and remote relay, but only behind the documented user-invoked bridge command. The install hook is limited to node-pty helper permissions. - **Files touched:** ~/.claude/settings.json, ~/.codex/config.toml, ~/.codex/hooks.json, ~/.gemini/settings.json, \/hooks.json - **Network endpoints:** http://127.0.0.1:\, configured gateway WebSocket URL ### Review decision - **Verdict:** Suspicious - **Confidence:** 95.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** \`dist/cli/src/runtime/bridge-session.js\` modifies Claude, Codex, Gemini, and Copilot hook configurations during \`linkshell start\`., The custom-shell path enables Codex hooks and installs broad lifecycle/permission hooks that POST agent events to a LinkShell localhost server., Bridge code relays terminal output and agent status over its configured gateway WebSocket. - **Evidence against:** \`scripts/postinstall.mjs\` only chmods package dependency \`node-pty\` spawn-helper candidates; it does not alter agent configuration., The control-surface writes occur only after the explicit \`linkshell start\` command, not during installation., Hook entries are marker-scoped and source includes cleanup/sweeping of LinkShell entries. ## Affected versions and remediation This report applies to linkshell-cli@0.5.27. - Review the evidence and your use of linkshell-cli@0.5.27 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.
