@factiii/runner@0.14.0

Factiii Runner, run Board AI agents on a machine you control. Pairs with the Factiii web/mobile clients over WebRTC.

AI Security Review

scanned 2mo ago · by lpm-firewall-ai

The package is not malicious under the install-hook policy because it has no registry install lifecycle hook and its setup is runtime-gated. Its automatic user-scoped AI-agent extension provisioning remains a concrete lifecycle risk.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

A user pairs and starts the runner, then an authorized Factiii setup request initializes a space.

Impact

The package can alter Claude and Codex control surfaces and run its hook on future agent events.

Mechanism

User-scoped AI-agent plugin and MCP provisioning with command hooks.

Decision evidence

public snapshot

AI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

Environment setup automatically provisions user-scoped Claude and Codex plugins and MCP entries.
The shipped plugin runs a command for agent prompt, stop, permission, notification, and session-end events.
Setup silently changes the user's Claude onboarding file.
The running daemon authenticates to a configured Factiii server with its pairing token.

Evidence against

package.json has no install, preinstall, or postinstall lifecycle hook.
The network connection and setup are reached through explicit CLI setup, connect, and start commands.
The hook script only reports local tmux state through a local Redis socket; no direct secret export was found.
