negotium@0.16.3
Install the Negotium multi-agent runtime and CLI with one package
AI Security Review
scanned 14d ago · by lpm-firewall-aiSource inspection did not substantiate the scanner's credential-redirect claim: the cited auth helpers select the configured or standard Codex auth path, and the inspected rollout code writes session files locally. The install hook downloads package-aligned binaries, with the browser installer enforcing a pinned SHA-256 digest, so the available evidence supports clean.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
npm postinstall downloads the supported platform binaries; the CLI and exported runtime code run when invoked by a user.
Impact
The inspected source supports ordinary runtime setup and session handling; it does not establish credential theft or agent-control hijacking.
Mechanism
The flagged auth-path code resolves a Codex auth file, while the rollout locations write Claude session data beneath the user's home directory. The inspected excerpts do not show those credentials being redirected to an unrelated recipient.

Decision evidence
public snapshotAI called this Clean at 85.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest exposes a CLI and defines a postinstall that runs two package-owned installer scripts.
- The browser installer downloads a release asset and rejects it if its SHA-256 digest differs from the pinned value.
- The Codex auth path references the caller's configured auth file or the standard CODEX_HOME auth file.
- The flagged source locations in agent-helpers.js, chunk-yf3nnkc1.js, hosted-agent.js, main.js, mcp-factories.js, and config.ts resolve the same Codex auth-file path helper.
- The flagged chunk-v18s6bj4.js and registry.js locations write Claude rollout/session files under the caller's home directory.
- The browser-runtime.js and query-runtime.js entry excerpts show bundled runtime imports; these excerpts do not establish a malicious behavior.
Evidence against
- The inspected postinstall installers fetch platform-specific binaries from the package's GitHub release and verify the browser binary against a pinned digest.
- The inspected source does not show the flagged auth-path helper sending credentials to an unofficial gateway or persisting a credential redirect.
