Multi-agent orchestration layer for OpenAI Codex CLI
AI Security Review
scanned 13d ago · by lpm-firewall-aiThe source shows a guarded, package-aligned native binary download during global installation, which leaves a lifecycle supply-chain risk. The inspected behavior does not support a malicious verdict.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Global npm installation of the package.
Impact
This adds an automatic publisher-controlled native binary download to global installation, creating a guarded lifecycle supply-chain boundary.
Mechanism
The postinstall hook calls native runtime hydration, which fetches a version-specific release manifest and asset, checks the archive size and SHA-256, then caches the selected binary.
AI rationale
The source shows a guarded, package-aligned native binary download during global installation, which leaves a lifecycle supply-chain risk. The inspected behavior does not support a malicious verdict.

Decision evidence
public snapshotAI called this Suspicious at 76.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json runs the postinstall script during installation.
- The postinstall path skips local installs and invokes native runtime hydration for global installs.
- Hydration can fetch a release asset for the package version and supported platform, then verify the archive size and SHA-256 before caching the binary.
Evidence against
- The download is tied to the package repository and release version; this inspection found no self-dependency chain or unconsented broad agent configuration mutation.
- The flagged agent integration locations are tests or setup code; they did not establish a separate attack path in this review.
