AI Security Review

scanned 9d ago · by lpm-firewall-ai

The postinstall replaces global agent instructions without asking, which creates an agent configuration lifecycle risk. The bundled content appears benign, so the source does not establish a concrete attack warranting a publish block.

Static reason

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

Trigger

Installing the package through npm, which runs its postinstall hook.

Impact

A user's existing global agent instructions may be replaced, changing later agent behavior.

Mechanism

The installer writes the bundled AGENTS.md to ~/.pi/agent/AGENTS.md whenever that file is absent or differs.

AI rationale

Evidence

package.jsonscripts/install-agents.mjsglobal/AGENTS.md~/.pi/agent/AGENTS.md

Decision evidence

public snapshot

AI called this Suspicious at 93.0% confidence as Dangerous Capability with high false-positive risk.

Evidence for warning

package.json runs scripts/install-agents.mjs automatically during postinstall.
The installer targets the global ~/.pi/agent/AGENTS.md and settings.json files.
If the existing AGENTS.md differs, the installer replaces it with the bundled copy without prompting.
The bundled file contains general coding-agent guidelines; settings logic only seeds a default theme when needed.

Evidence against

The replaced instructions are ordinary coding guidance, with no observed credential collection, data export, or malicious directives.
The theme setting is only initialized when absent or unset.
