negotium@0.18.0

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

AI Security Review

scanned 14d ago · by lpm-firewall-ai

Inspected source shows the postinstall downloaders verify pinned release binaries before installation. Vault API keys are passed to the package’s Maestro provider, but the inspected code does not establish an unrestricted credential destination or a concrete attack; the scanner signals alone do not support a warning or block.

Static reason

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

Trigger

npm postinstall triggers the two installer scripts.

Impact

No confirmed compromise or unauthorized configuration change was established. Provider API keys are passed to the Maestro provider, with no unrestricted recipient established by inspected source.

Mechanism

The scripts select a platform-specific asset from the project’s GitHub release, verify its SHA-256 digest, then install it in the Negotium state directory.

Decision evidence

public snapshot

AI called this Clean at 87.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

package.json exposes agent runtime modules; the inspected target locations mostly contain path handling and rollout-file operations, not foreign agent configuration changes.
The postinstall scripts download version-pinned binaries from the project’s GitHub releases and verify their SHA-256 before installation under the Negotium state directory.
The inspected API-key override code reads DeepSeek, Moonshot, and GLM keys from the user vault and passes them to the Maestro provider; no unrestricted recipient or actual network send was established in inspected source.

Evidence against

The package has a postinstall hook that runs two binary installer scripts.
Vault API keys are forwarded to the Maestro provider, but inspected source does not establish an unrestricted or unrelated destination.
