It registers instructions, hooks, MCP servers, plugins, and package runtime code that run during later agent events. - **Trigger:** Installing or updating the package globally through npm. - **Impact:** The package gains persistent execution and control over AI-agent sessions across the user's installed hosts. - **Evidence paths:** package.json, scripts/postinstall.js, scripts/lib/npm-lifecycle-adapter.js, scripts/lib/global-host-config.js, scripts/lib/global-host-target.js, hooks/\_runtime/host-hook-launcher.cjs - **Review source:** ai\_review - **Reviewed:** 2026-08-29T19:25:55.156Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall applies multi-host user-level agent configuration and command hooks. - **Attack narrative:** The package uses npm postinstall as an automatic installer for a broad user-level AI-agent control surface. A global installation applies configuration for Copilot, Claude, Codex, Gemini, Grok, and Cursor, including hooks that later spawn package adapters with the active environment. This is not limited to package-owned state or an explicit follow-up command, so installing the package changes unrelated host configurations and creates persistent agent-session execution. - **Rationale:** The source confirms unconsented postinstall mutation of broad, foreign AI-agent configuration and hooks on global install. This meets the install-control-surface block policy despite no observed exfiltration or network payload. - **Files touched:** ${HOME}/.copilot, ${HOME}/.claude, ${HOME}/.codex, ${HOME}/.gemini, ${HOME}/.grok, ${HOME}/.cursor, ${HOME}/.agents ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The manifest runs a postinstall script., On every global install, the lifecycle adapter selects an execute action., The postinstall path applies global host configuration without a separate setup command., The default target set covers six AI coding hosts., It writes user-level instructions, hooks, MCP settings, and runtime files; installed hooks launch package code for future agent events. - **Evidence against:** Workspace installs are skipped and instruct the user to perform a global install., No runtime self-dependency is declared., No network request or credential-exfiltration behavior was found in the inspected runtime paths. ## Public findings ### 1.
