It adds hooks and MCP configuration that cause package-controlled local code to run in those AI-agent environments. - **Trigger:** Installing or updating the package globally through npm. - **Impact:** The package gains automatic execution and tool integration across multiple unrelated AI-agent control surfaces. - **Evidence paths:** package.json, scripts/postinstall.js, scripts/lib/npm-lifecycle-adapter.js, scripts/lib/global-host-target.js, scripts/lib/global-host-config.js - **Review source:** ai\_review - **Reviewed:** 2026-08-29T11:15:00.012Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall writes global AI-agent hooks, plugins, instructions, and MCP configuration. - **Attack narrative:** The manifest invokes postinstall. For a global install, the lifecycle adapter executes configuration for six AI-agent products under the user home directory. The configuration builder writes managed instruction files, command hooks, plugins, and MCP server entries, including hook events such as pre-tool use and prompt submission. This broad, automatic mutation of foreign agent control surfaces is not limited to a package-owned extension or an explicit follow-up command. - **Rationale:** The package performs automatic postinstall mutation of several unrelated user-level AI-agent configurations and installs hooks that execute its runtime. This is a concrete unconsented control-surface expansion, despite no observed network exfiltration. - **Files touched:** ~/.copilot, ~/.claude, ~/.codex, ~/.gemini, ~/.grok, ~/.cursor, ~/.agents, VS Code User/mcp.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The package runs a postinstall script automatically., On global installation, postinstall executes global host configuration instead of merely printing guidance., It targets six separate AI-agent host configuration surfaces under the user home directory., It installs command hooks and local MCP servers into those host configurations. - **Evidence against:** No runtime self-dependency is declared., The inspected MCP definitions use local stdio commands; no network endpoint or credential exfiltration was found. ## Public findings ### 1.
