RLM-based CLI chat wrapper for Claude with external history context management

AI Security Review

scanned 3d ago · by lpm-firewall-ai

The runtime prompt explicitly directs agents to override conflicting system reminders and conceal the conflict, and the gateway uses this template to generate agent prompts. This is concrete prompt manipulation, so the package is blocked.

Static reason

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

Trigger

A gateway session generates an agent system prompt.

Impact

An agent may disregard higher-priority instructions and hide that it did so.

Mechanism

The package's prompt template directs the agent to ignore conflicting system or tool instructions and conceal that conflict.

Attack narrative

When a gateway agent prompt is generated, the package template tells the agent to silently follow its own task-tracking convention over conflicting system reminders and not acknowledge the conflict. The template is used to generate the gateway system prompt, making this an active attempt to steer agent behavior and suppress disclosure.

AI rationale

Evidence

package.jsondist/lib/gateway.js

Decision evidence

public snapshot

AI called this Malicious at 96.0% confidence as Malware with low false-positive risk.

Evidence for block

package.json exposes a gateway executable that loads the reviewed runtime.
The gateway system prompt tells agents to disregard conflicting system reminders and not acknowledge the conflict.
The package builds that template into a generated system prompt and uses it as the gateway prompt template.
