negotium@0.2.30

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

AI Security Review

scanned 2mo ago · by lpm-firewall-ai

The lifecycle scripts are transparent, checksum-verify fixed package-aligned releases, and write only Negotium-owned state. Source inspection found no concrete malicious chain, credential exfiltration, or unconsented foreign AI-agent control-surface mutation.

Static reason

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

Trigger

npm postinstall; subsequently explicit negotium CLI/runtime commands

Impact

Installs executable helper binaries under the package-owned state directory; no secret exfiltration, foreign agent-config mutation, or remote payload execution was found.

Mechanism

verified optional native-helper installation and local agent runtime

AI rationale

Decision evidence

public snapshot

AI called this Clean at 90.0% confidence as Benign with medium false-positive risk.

Evidence for AI clean decision

package.json runs two postinstall scripts.
Install scripts download native tool binaries to ~/.negotium/binaries.

Evidence against

Both download URLs and SHA-256 hashes are hard-coded and verified.
Downloads are package-aligned GitHub releases and can be skipped via NEGOTIUM_SKIP_* env vars.
Install failures only disable optional tools and exit successfully.
Runtime source uses per-turn Codex MCP overrides and states global config.toml remains untouched.
Credential paths are checked or copied into isolated temporary homes; no exfiltration path was found.
