negotium@0.21.1
Install the Negotium multi-agent runtime and CLI with one package
AI Security Review
scanned 14d ago · by lpm-firewall-aiThe inspected evidence does not support the scanner's malicious label: flagged agent locations show ordinary package runtime paths and session handling, and the install hook invokes package-owned installers. No concrete attack behavior was established.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
npm installation triggers the postinstall installers; agent and browser behavior requires use of the package runtime.
Impact
No malicious impact was established from the inspected source.
Mechanism
The inspected agent locations resolve authentication paths or write session rollout files. The supplied excerpts do not establish credential forwarding or unconsented mutation of a foreign agent control surface.
AI rationale
The inspected evidence does not support the scanner's malicious label: flagged agent locations show ordinary package runtime paths and session handling, and the install hook invokes package-owned installers. No concrete attack behavior was established.
Decision evidence
public snapshotAI called this Clean at 79.0% confidence as Benign with medium false-positive risk.
Evidence for AI clean decision
- package.json runs two package-owned binary installers at postinstall.
- The flagged auth-path helper locations resolve the Codex auth file from CODEX_HOME or the user's .codex directory.
- The Claude integration writes synthetic session rollouts under ~/.claude/projects.
- The hosted-agent code scopes CODEX_HOME for its child environment.
- The registry code copies a session rollout into a project-specific Claude directory only when the destination is absent.
- The flagged query and browser runtime files contain ordinary logger and browser-process imports; no attack behavior is established by these excerpts.
Evidence against
- The package has a postinstall hook, so its installer behavior merits review.
- The browser runtime imports child_process, but this excerpt does not show malicious execution.
