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

AI Security Review

scanned 14d ago · by lpm-firewall-ai

The inspected install-time network behavior is limited to downloading hash-checked, package-related binaries. Flagged credential and agent-integration locations show auth-path resolution, isolated Codex home selection, or session data handling; they do not establish credential forwarding or an unconsented control-surface change.

Static reason

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

Trigger

Installing the package triggers its postinstall helpers.

Impact

No confirmed credential theft, agent control hijack, or other attack impact was established.

Mechanism

The helpers fetch versioned assets from the package’s GitHub organization, check their SHA-256 hashes, and install them in a package-specific state directory.

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

package.json defines a postinstall that runs two helper installers.
The installers fetch fixed release assets from the package’s GitHub organization, verify SHA-256 hashes, and place binaries in the Negotium state directory.
The flagged Codex auth paths locate auth.json; the inspected agent code uses an isolated CODEX_HOME when needed, and the other flagged locations concern agent session data or path setup.
The inspected runtime entry files show no evidence of credential forwarding, broad agent-control mutation, or another concrete attack.
