Install the Negotium multi-agent runtime and CLI with one package

AI Security Review

scanned 14d ago · by lpm-firewall-ai

The flagged install behavior is bounded to downloading fixed-version runtime helpers and verifying their hashes. The inspected credential and agent integration locations do not establish credential exfiltration or unconsented agent control-surface mutation.

Static reason

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

Trigger

Package installation runs the postinstall helpers; the peer bridge runs when its URL and token settings are provided.

Impact

No confirmed attack surface was established; the inspected behaviors support package runtime setup and local peer communication.

Mechanism

The helpers place binaries in the package state directory and verify their checksums. The bridge rejects non-loopback URLs before sending its request and bearer token.

AI rationale

Decision evidence

public snapshot

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

Evidence for AI clean decision

The postinstall hook runs two helpers that install fixed-version browser and bash binaries into the package’s state directory; each helper checks the downloaded binary’s SHA-256 before replacing it.
The peer bridge only activates when both bridge settings are supplied, restricts its URL to HTTP loopback hosts, and sends the bridge token and request to that loopback destination.
The inspected agent-related locations reference Codex authentication paths or write session data into Claude project storage; they do not establish unconsented agent configuration changes.
The query-runtime excerpt shows ordinary logger setup; the browser-runtime excerpt imports process and file utilities, with no malicious behavior established by the inspected source.
