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

AI Security Review

scanned 14d ago · by lpm-firewall-ai

Source inspection did not substantiate the scanner's credential-redirection or command-output-exfiltration claims. The install hook performs checksum-verified vendor binary setup, and the flagged agent locations show ordinary configuration and runtime behavior.

Static reason

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

Trigger

npm postinstall runs the two package-local installers.

Impact

No confirmed credential theft, command-output exfiltration, or agent control-surface mutation was established.

Mechanism

The installers fetch platform-specific binaries from vendor release URLs and verify them against pinned SHA-256 values before saving them.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 96.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

package.json routes the postinstall hook to two package-local binary installers; the browser installer downloads from its vendor release and verifies a fixed SHA-256 checksum before saving the binary.
The flagged agent-integration offsets resolve to ordinary package behavior: auth-file path helpers, prompt batching, rollout-file writing, trusted workspace roots, and registry rollout storage.
The browser runtime uses a capability header for requests to a local loopback service; the runtime helper bundle exports model and context constants.
The main bundle sets a DeepSeek API URL for cron prompt summaries, and the MCP client sends a configured token to its configured URL; inspected source does not establish an unrelated credential recipient.

Evidence against

The automatic postinstall downloads executable binaries, but the inspected browser installer pins a vendor release and rejects checksum mismatches; no broad project or agent-configuration mutation was found in the installer source.
Scanner claims of credential redirection and command-output exfiltration were not substantiated by the inspected source excerpts.
