On normal server startup, the package conditionally downloads and executes three external Bun packages to provision AI-agent extensions. This is an unprompted foreign agent-control-surface mutation, though no concrete exfiltration chain is present in inspected source. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 88.0% - **Started:** 2026-08-09T14:38:25.145Z - **Finished:** 2026-08-09T14:39:27.967Z - **Download time:** 508 ms - **Static scan time:** 1119 ms - **AI review time:** 61194 ms - **Total time:** 62822 ms ## Security analysis ### Published attack-surface review - **Summary:** On normal server startup, the package conditionally downloads and executes three external Bun packages to provision AI-agent extensions. This is an unprompted foreign agent-control-surface mutation, though no concrete exfiltration chain is present in inspected source. - **Trigger:** User starts AgentGUI while any configured marker directory is absent. - **Impact:** Remote package contents can modify OpenCode, Gemini, or Kilo extension/config areas. - **Evidence paths:** package.json, scripts/patch-fsbrowse.js, server.js, lib/server-startup.js, lib/gm-agent-configs.js, electron/main.js, lib/terminal.js, lib/ws-setup.js - **Review source:** ai\_review - **Reviewed:** 2026-08-09T14:39:27.967Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic \`bun x\` execution for third-party agent-extension provisioning. - **Rationale:** The automatic runtime provisioning of foreign AI-agent extensions is a real supply-chain/control-surface risk and merits a warning. Inspected lifecycle, Electron, terminal, and database code do not establish malicious behavior. - **Files touched:** lib/gm-agent-configs.js, lib/server-startup.js, ~/.config/opencode/agents, ~/.gemini/extensions/gm/agents, ~/.config/kilo/agents ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** Startup automatically invokes unpinned \`bun x\` packages \`gm-oc\`, \`gm-gc\`, and \`gm-kilo\` when markers are absent., Those packages target OpenCode, Gemini, and Kilo agent-extension directories under the user home directory. - **Evidence against:** \`postinstall\` only patches the local \`fsbrowse\` dependency and rebuilds \`better-sqlite3\`., Electron network activity is a localhost readiness poll, not command-output upload., Terminal shell access requires both \`PASSWORD\` and explicit \`ENABLE\_TERMINAL=1\`., No package-owned source showed credential exfiltration or a hardcoded external collection endpoint. ## Public findings ### 1.
