oh-my-codex@0.21.7
Multi-agent orchestration layer for OpenAI Codex CLI
AI Security Review
scanned 24d ago · by lpm-firewall-aiThe postinstall handler limits its behavior to global installs, runtime hydration, and an install stamp; it describes setup as explicit opt-in. The CLI setup path has a concrete first-party agent configuration capability, so this warrants a warning under the agent integration policy, but the inspected evidence does not show an automatic install-time control-surface attack.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
A user invokes `omx setup` or `omx update`.
Impact
The command changes the user's agent setup; the inspected lifecycle hook does not trigger that setup automatically.
Mechanism
Setup synchronizes managed configuration and agent files into the selected Codex scope, with overwrite safeguards for existing AGENTS.md files.
AI rationale

Decision evidence
public snapshotAI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The postinstall hook loads its handler, but local installs exit without running setup.
- The CLI passes explicit arguments to its command handler, and setup can write managed agent configuration when invoked.
- Setup asks before overwriting an existing AGENTS.md unless an explicit force option is used.
Evidence against
- The global-install postinstall path hydrates a native runtime and records the installed version; it does not itself invoke setup.
- The inspected setup code backs up managed content before writing it and supports dry-run behavior.
