AI employee operating system — persistent memory, task management, and multi-agent coordination for Claude Code.

AI Security Review

scanned 11d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. Installing the package runs a postinstall hook that writes Claude Code skills under the user home directory without a consent prompt. If a previous setup marker exists, the same hook also rewrites Claude settings hooks and the global MCP config so later Claude sessions execute this package.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

npm install lifecycle postinstall, which always launches install.js --commands-only when dist/bin/install.js is present.

Impact

Claude Code gains package-controlled skills on install, and on later installs can run package hook commands on tool use and prompts and load the package MCP server.

Mechanism

copySlashCommands writes skill files into ~/.claude/skills before any setup check. When setup-state.json or config.json already exists, mergeHooks writes command hooks into ~/.claude/settings.json and registerMcpServer writes an MCP server into ~/.claude.json.

Policy narrative

On npm install, postinstall.mjs starts dist/bin/install.js with --commands-only. That path always copies this package's skill files into the user's ~/.claude/skills directory, including before any setup command. If ~/.exe-os already has setup state, the same install also merges Claude hooks into ~/.claude/settings.json and registers an MCP server in ~/.claude.json. Those hooks include a PreToolUse command covering Write, Edit, Read, Bash, Task, and Agent. The user does not confirm this during the npm install itself.

AI rationale

The postinstall hook writes Claude Code skill files on every install and, after a prior setup marker, also rewrites Claude hook settings and MCP config. That is unconsented install-time mutation of a foreign agent control surface.
