It registers package code as an MCP server and installs hooks across prompt, tool, and session events. - **Trigger:** npm install or update after ~/.exe-os/setup-state.json or ~/.exe-os/config.json exists - **Impact:** Package code executes in future Claude Code sessions and observes broad agent lifecycle/tool activity. - **Evidence paths:** package.json, dist/bin/install.js, dist/chunk-QVM5KATG.js, dist/hooks/post-tool-combined.js, dist/hooks/prompt-submit.js, dist/hooks/stop.js - **Review source:** ai\_review - **Reviewed:** 2026-07-30T11:53:07.085Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall writes global MCP configuration and broad Claude hooks - **Attack narrative:** The package's npm postinstall invokes an installer that, on machines previously set up for exe-os, adds its MCP server to ~/.claude.json and broad command hooks to ~/.claude/settings.json. Those hooks execute package code on prompts, tool calls, session events, and stop events; the post-tool matcher includes Bash, file operations, Agent, and all MCP tools. This is unconsented install-time mutation of a foreign, broad AI-agent control surface. - **Rationale:** Source inspection confirms the lifecycle script persistently wires package-controlled code into Claude Code's global configuration and hooks. This meets the firewall block policy for postinstall mutation of a foreign/broad AI-agent control surface. - **Files touched:** package.json, dist/bin/install.js, dist/chunk-QVM5KATG.js, ~/.claude.json, ~/.claude/settings.json, ~/.claude/skills, ~/.exe/mcp.json, ~/.exe-os/logs/hooks.log ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json postinstall runs dist/bin/install.js --commands-only., dist/bin/install.js calls registerMcpServer and mergeHooks during postinstall once ~/.exe-os setup state exists., dist/chunk-QVM5KATG.js writes a package MCP server to ~/.claude.json., dist/chunk-QVM5KATG.js installs command hooks for Claude events including prompts, tool use, and session lifecycle., The hook matcher covers Bash, Edit, Write, Read, Glob, Grep, Agent, and mcp\_\_.\*. - **Evidence against:** The postinstall path skips MCP/hook registration before package setup state exists., No external network endpoint is used by the inspected postinstall registration path. ## Public findings ### 1.
