A global npm install can also create OS login persistence for its daemon. - **Trigger:** npm postinstall; autostart applies when npm global-install signals are present. - **Impact:** Unconsented modification of broad AI-agent control surfaces plus persistent background execution. - **Evidence paths:** package.json, scripts/postinstall-sync-skills.mjs, dist/cli/installers/postinstall-skill-sync.js, dist/chunk-ZMNEWS7A.js, dist/chunk-VW5VSUEN.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T10:16:54.608Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall writes foreign agent skill directories and installs daemon autostart - **Attack narrative:** On installation, the lifecycle wrapper loads runPackagePostinstall. That path syncs bundled skills in global mode to OpenCode, Codex, Claude Code, and Amp directories. When npm identifies a global install, it also repairs or creates a per-user launch agent or scheduled task that runs the package daemon at login. These mutations occur without an explicit user setup command. - **Rationale:** This is concrete postinstall mutation of several foreign/global AI-agent control surfaces, meeting the blocking policy. The additional daemon autostart increases persistence risk. - **Files touched:** package.json, scripts/postinstall-sync-skills.mjs, dist/cli/installers/postinstall-skill-sync.js, dist/chunk-ZMNEWS7A.js, dist/chunk-VW5VSUEN.js ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall automatically., scripts/postinstall-sync-skills.mjs imports the built postinstall installer., dist/cli/installers/postinstall-skill-sync.js invokes global skill sync during postinstall., dist/chunk-ZMNEWS7A.js writes bundled skills into Codex, Claude Code, Amp, and OpenCode global directories., dist/cli/installers/postinstall-skill-sync.js also installs/repairs daemon autostart for global npm installs., dist/chunk-VW5VSUEN.js creates a macOS LaunchAgent or Windows logon task running the package CLI. - **Evidence against:** No confirmed secret harvesting or external exfiltration path was found., Relay networking is loopback-constrained in dist/chunk-NYJDZITI.js. ## Public findings ### 1.
