AI Security Review

scanned 1mo ago · by lpm-firewall-ai

This is a real, user-invoked AI-agent capability installation and MCP configuration path. It is not malicious install-hook abuse because npm installation only prints a message and no automatic exfiltration or payload chain was found.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

Running npx analyzthis_design with no command or the install command.

Impact

It can alter AI-tool behavior in user and project configuration locations.

Mechanism

Copies AI-agent skills and registers an MCP server.

Decision evidence

public snapshot

AI called this Suspicious at 90.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The default CLI command runs the installer, which copies package-supplied skills into AI-tool directories.
The installer also creates project command files and automatically adds an MCP server entry for supported AI tools.
The package can submit feedback to its service, although submission is gated by explicit consent.

Evidence against

The npm postinstall hook only prints usage guidance; it does not invoke the installer.
Feedback text is redacted for paths, email addresses, and common API-key patterns before submission.
No self-dependency, hidden payload loading, shell execution, or install-time network request was found.
