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

AI Security Review

scanned 3mo ago · by lpm-firewall-ai

Source inspection found powerful but package-aligned, user-invoked agent and gateway functionality, not a concrete malicious chain. Install-time hooks do not perform runtime mutation.

Static reason

One or more suspicious static signals were detected.

Trigger

Explicit CLI, gateway, or authenticated API use

Impact

User-authorized commands can modify files or run shell commands; no covert install-time action was found.

Mechanism

Local Claude subprocess orchestration and configured gateway services

AI rationale

Source inspection found powerful but package-aligned, user-invoked agent and gateway functionality, not a concrete malicious chain. Install-time hooks do not perform runtime mutation.

Decision evidence

public snapshot

AI called this Clean at 91.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

Agent tools can run shell commands during an explicit Claude/gateway session (dist/lib/tools/bash.js).

Evidence against

package.json has no preinstall/install/postinstall hook.
Gateway persistence is only offered after explicit cumulus-gateway setup confirmation (dist/gateway/setup.js).
Runtime update installs are reachable through explicit update commands or authenticated admin API (dist/lib/version-check.js, dist/gateway/server.js).
API-key-based authentication gates non-public gateway routes (dist/gateway/auth.js, dist/gateway/server.js).
No credential-harvesting or covert exfiltration path was found in inspected source.
