oh-my-codex@0.21.3
Multi-agent orchestration layer for OpenAI Codex CLI
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe package has a concrete automatic remote native-payload delivery path, but the inspected source shows no self-dependency, credential theft, broad agent-control mutation, or direct malicious action. The risk warrants a warning rather than a block.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
Global installation of the package through npm.
Impact
A compromised release endpoint or manifest can cause a later OMX command to use a downloaded executable.
Mechanism
Automatic remote native-binary hydration through a release manifest.
AI rationale
The package has a concrete automatic remote native-payload delivery path, but the inspected source shows no self-dependency, credential theft, broad agent-control mutation, or direct malicious action. The risk warrants a warning rather than a block.

Decision evidence
public snapshotAI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The automatic postinstall hook imports and runs package code.
- That code runs for global installs and hydrates a native runtime.
- Hydration fetches a release manifest and downloads a native archive selected by it.
- The downloaded archive is checksum-checked only against the fetched manifest, then cached for later execution.
Evidence against
- The postinstall path returns without action for non-global installs.
- Setup writes agent configuration only through the explicit omx setup command.
- No runtime dependency on oh-my-codex itself is declared.
- The fetched artifacts are tied to this package's GitHub release path and have size and hash checks.
