AI Security Review

scanned 2h ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. Automatic installation changes the consumer project's AI-agent control files and Git hook configuration. It installs a Claude Stop hook that executes package-provided code.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review

Trigger

Installing @softize/opus through npm, unless OPUS_SKIP_INIT is set.

Impact

A dependency install can alter Claude behavior and repository hooks without an explicit setup command.

Mechanism

Postinstall materializes agent skills, hooks, instructions, and Git hooks into the consumer project.

Policy narrative

npm executes the package postinstall, which identifies the consumer project and calls its initializer. The initializer materializes package-controlled content into AGENTS.md, Claude skills and settings, and Git hooks. It configures a Claude Stop hook to execute a package-provided script and changes Git hook settings. These changes occur without requiring the user to run the documented setup command.

Rationale

This is an unconsented postinstall mutation of broad AI-agent and repository control surfaces in the consuming project. The lack of observed network exfiltration does not neutralize the automatic control-surface changes.
