Open JS agent harness built on pi-mono, floosie, xstate, and anentrypoint-design

AI Security Review

scanned 4d ago · by lpm-firewall-ai

No unconsented install-time or import-time attack chain is established. The package is an explicit agent harness with runtime shell, messaging, and Home Assistant capabilities.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

User runs the Freddie CLI or enables and invokes a registered tool.

Impact

Capabilities can be powerful when intentionally enabled, but inspected source does not harvest or exfiltrate credentials or persist into foreign agent control surfaces.

Mechanism

User-invoked plugin tools use configured credentials and local/runtime capabilities.

Rationale

Scanner findings map to package-aligned, user-invoked agent functionality rather than a concrete malicious chain. No lifecycle execution, covert credential exfiltration, foreign AI-agent control-surface mutation, or remote payload staging was found in inspected source.

Evidence

Decision evidence

public snapshot

AI called this Clean at 90.0% confidence as Benign with medium false-positive risk.

Evidence for block

`plugins/bash/handler.js` exposes a shell-execution tool in the `core` toolset.
`plugins/homeassistant_tool/handler.js` sends its configured HASS bearer token to the configured Home Assistant API.

Evidence against

`package.json` has no preinstall, install, postinstall, or prepare lifecycle hook.
`bin/freddie.js` only boots the host after an explicit CLI invocation.
`plugins/homeassistant_tool/handler.js` requires `HASS_TOKEN` and targets user-configured `$HASS_URL` or local Home Assistant.
`plugins/send_message/handler.js` dynamically imports only a fixed allowlist of platform adapters.
`src/host/index.js` loads plugins during explicit host startup; inspected code shows no foreign AI-agent config mutation.
`src/cli/uninstall.js` only removes Freddie's own home directory when explicitly requested.
