Those hooks execute package code across broad Claude lifecycle events. - **Trigger:** npm install or package upgrade on a non-Windows host with existing ~/.exe-os setup state. - **Impact:** Package code gains recurring execution in Claude Code sessions and can influence agent tool and prompt lifecycle. - **Evidence paths:** package.json, postinstall.mjs, dist/bin/install.js, dist/chunk-U32RDCUB.js, dist/hooks/post-tool-combined.js, dist/hooks/prompt-submit.js - **Review source:** ai\_review - **Reviewed:** 2026-08-06T20:14:16.826Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall registration of global MCP server, skills, and command hooks - **Attack narrative:** Installing or upgrading the package runs postinstall.mjs, which invokes the installer without an explicit user command. For users with existing package state, it writes a global Claude MCP entry and injects commands that execute package hook scripts on session, prompt, tool, and stop events. This is an unconsented install-time mutation of a foreign, broad AI-agent control surface. - **Rationale:** The lifecycle path is concrete and reaches global Claude configuration and recurring command hooks. This meets the blocking policy regardless of scanner similarity labels. - **Files touched:** postinstall.mjs, dist/bin/install.js, dist/chunk-U32RDCUB.js, ~/.claude.json, ~/.claude/settings.json, ~/.claude/skills, ~/.exe/mcp.json ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall.mjs automatically., postinstall.mjs invokes dist/bin/install.js --commands-only., dist/bin/install.js calls registerMcpServer and mergeHooks during postinstall after setup state exists., dist/chunk-U32RDCUB.js writes ~/.claude.json MCP configuration and ~/.claude/settings.json., mergeHooks installs package commands for Claude SessionStart, UserPromptSubmit, PreToolUse, PostToolUse, Stop, and other events., postinstall also copies package-authored skills into ~/.claude/skills. - **Evidence against:** The observed network endpoint in dist/chunk-J73I53JO.js is user-consented cloud setup, not lifecycle exfiltration., The postinstall skips MCP/hooks on a fresh setup state, but mutates them automatically for existing users. ## Public findings ### 1.
