AI Security Review
scanned 11d ago · by lpm-firewall-aiThe install-time skill deployment is a real agent extension lifecycle risk and warrants a warning. The inspected behavior is package-owned skill setup with destination safeguards, so it does not meet the blocking criteria for an unconsented foreign or broad control-surface mutation.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source
Trigger
Installing the package through npm with the postinstall hook enabled.
Impact
The installed skills become available to the user’s agent; source inspection does not establish broader configuration takeover or malicious execution.
Mechanism
The hook selects the default Codex skills root and installs bundled skill files there, subject to skip and destination-preservation checks.
AI rationale
The install-time skill deployment is a real agent extension lifecycle risk and warrants a warning. The inspected behavior is package-owned skill setup with destination safeguards, so it does not meet the blocking criteria for an unconsented foreign or broad control-surface mutation.

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package runs scripts/postinstall.mjs during installation.
- The postinstall hook automatically installs bundled skills unless an environment variable disables it or the package is installed from its own directory.
- The default destination is the user’s Codex skills directory, and the hook selects that default when no custom root is provided.
- The skill manager copies package-bundled files to the destination and skips existing unmanaged or modified destinations.
- This is a first-party package skill setup; the inspected source does not establish a foreign or broad agent configuration takeover.
Evidence against
- dist/auth/google-oauth.js uses a loopback callback to complete Google login through the supplied authentication client.
- dist/preflight.js requests bootstrap data from the configured service URL.
