AI Security Review
scanned 26d ago · by lpm-firewall-aiThe package performs an unconsented postinstall invocation that installs AI-agent skills at project or global scope. This meets the install-control-surface blocking rule.
Static reason
One or more suspicious static signals were detected.
Trigger
npm installation runs the postinstall hook.
Impact
It can alter AI-agent skill control locations without an explicit user command or prompt.
Mechanism
The hook launches a platform-specific cio binary with the skills install command and a global or project flag.
Policy narrative
The package's postinstall hook resolves a platform binary and runs its skills-install command. For ordinary project installs it changes the working directory to the directory from which installation was started; for global installs it chooses global scope. Package text identifies this command as writing agent-skill locations used by Claude and open-agent tools. This is an automatic lifecycle mutation of a broad AI-agent control surface.
AI rationale
The package performs an unconsented postinstall invocation that installs AI-agent skills at project or global scope. This meets the install-control-surface blocking rule.
Evidence

Evidence for policy risk

- The hook automatically runs the platform binary's skills-install command with global or project scope and targets the installing project's directory.
- The package text identifies the command as installing agent skills into Claude and open-agent skill locations.
