The autorun starts the package's background daemon at the next login. - **Trigger:** npm postinstall - **Impact:** Unconsented persistence and automatic background execution of kcgrouter. - **Evidence paths:** package.json, scripts/postinstall.mjs, src/cli/index.ts, src/cli/daemon.ts - **Review source:** ai\_review - **Reviewed:** 2026-08-14T15:24:54.079Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** writes Windows Startup, macOS LaunchAgent, or Linux XDG autostart entries - **Rationale:** The package has concrete unconsented install-time persistence, which warrants a warning. It does not meet the block threshold because the persistence runs its own daemon and no foreign/broad AI-agent control surface or malicious payload chain was found. - **Files touched:** scripts/postinstall.mjs, ~/.kcgrouter/scripts/kcgrouter-startup.vbs, ~/Library/LaunchAgents/com.kcgrouter.plist, ~/.config/autostart/kcgrouter.desktop ### Review decision - **Verdict:** Suspicious - **Confidence:** 96.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** package.json runs a postinstall script automatically., postinstall registers OS autostart unless an environment opt-out is set., It writes a Windows Startup VBS that silently launches \`kcgrouter --daemon\`., It also creates macOS LaunchAgent and Linux XDG autostart entries. - **Evidence against:** Autorun launches the package's own named daemon; no foreign AI-agent control surface is modified., Inspected startup code contains no network or credential-exfiltration path., Runtime network code is consistent with the stated AI proxy purpose. ## Public findings ### 1.
