negotium@0.7.0

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

AI Security Review

scanned 2mo ago · by lpm-firewall-ai

Source inspection found legitimate but powerful installer and agent-runtime behavior, with checksum verification and explicit provider configuration. The scanner's concrete malicious claims were not substantiated by the inspected files.

Static reason

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

Trigger

Package installation or explicit runtime use of its CLI and cron features.

Impact

No unconsented credential theft, remote payload execution, or foreign AI-agent control-surface mutation was confirmed.

Mechanism

Verified binary installation and configured model-provider requests.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 82.0% confidence as Benign with medium false-positive risk.

Evidence for AI clean decision

The postinstall hook runs two bundled binary installers.
A cron-summary feature can send a scheduled prompt to the configured DeepSeek API when an API key is present.

Evidence against

Each installer verifies a pinned SHA-256 digest before installing its binary.
The observed network calls are package-aligned binary downloads, local services, or the documented model-provider feature.
No source evidence supports the scanner's claimed credential redirect, foreign-package overwrite, or command-output exfiltration.
