oh-my-codex@0.21.13
Multi-agent orchestration layer for OpenAI Codex CLI
AI Security Review
scanned 19d ago · by lpm-firewall-aiThe lifecycle hook does not reach agent setup, but the explicit setup command installs package-owned behavior-bearing agent configuration. This merits a warning for agent capability, without evidence of a confirmed attack.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
A user runs the package’s setup command.
Impact
The installed agent instructions can influence later Codex behavior; the inspected install hook does not perform this setup automatically.
Mechanism
Setup generates agent TOML from package prompts and writes it to user or project Codex agent directories.
AI rationale
The lifecycle hook does not reach agent setup, but the explicit setup command installs package-owned behavior-bearing agent configuration. This merits a warning for agent capability, without evidence of a confirmed attack.
Evidence
package.jsondist/scripts/postinstall.jsdist/cli/index.jsdist/cli/setup.jsdist/agents/native-config.js~/.codex/agents/./.codex/agents/
Decision evidence
public snapshotAI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The manifest runs a postinstall script that calls the package’s postinstall module.
- The postinstall exits for local installs; for global installs it hydrates the native runtime and records version information.
- The CLI dispatches setup only when the user invokes the setup command.
- Setup generates agent configuration from package prompts and writes TOML files into Codex agent directories.
Evidence against
- The inspected install hook does not invoke setup or install agent configuration.
