AI Security Review

scanned 7d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. Automatic postinstall can place package-supplied agents and skills into GitHub Copilot's user control surface without confirmation. This affects a foreign AI harness beyond the installed package directory.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

An npm installation with lifecycle scripts enabled, successful binary provisioning, and no available interactive terminal.

Impact

Package-authored instructions become available to the user's AI harness without explicit consent, potentially influencing subsequent agent behavior.

Mechanism

The postinstall script selects GitHub Copilot by default in noninteractive mode and copies bundled agent and skill files into its user directory.

Policy narrative

During installation, the postinstall script invokes harness asset setup. When no interactive terminal is available and no harness override is supplied, it automatically selects GitHub Copilot. The asset installer copies bundled agents and skills into the user's .copilot directory. Interactive prompting and conflict preservation do not guard this noninteractive path, which mutates a foreign AI-agent control surface without confirmation.

AI rationale

Source establishes unconsented postinstall mutation of a foreign AI-agent control surface, meeting the specified blocking policy. The interactive consent path does not protect noninteractive installations.
