AI Security Review
scanned 6d ago · by lpm-firewall-aiThe postinstall hook automatically modifies the user's agent skill directory, creating a residual agent-extension lifecycle risk. The files are bundled product skills, and the installer avoids replacing unmanaged or modified copies, so the inspected source does not establish malicious behavior.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
The package's postinstall hook runs and its install-context check passes.
Impact
The package can alter a first-party agent extension without a separate confirmation at install time; source limits replacement of unmanaged or modified skill directories.
Mechanism
The hook calls the skill installer, which copies bundled files and replaces the target directory when installation or update proceeds.
AI rationale
The postinstall hook automatically modifies the user's agent skill directory, creating a residual agent-extension lifecycle risk. The files are bundled product skills, and the installer avoids replacing unmanaged or modified copies, so the inspected source does not establish malicious behavior.

Decision evidence
public snapshotAI called this Suspicious at 90.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The manifest runs the postinstall script automatically when the package is installed.
- When its install-context check passes, the hook installs skills into the Codex skills root by default.
- The default skill root is under the user's home directory at .codex/skills.
- The installer copies bundled skill files into a staged directory and swaps that directory into the target.
- The installer skips existing unmanaged or modified skills unless force is enabled.
Evidence against
- The installed files are bundled product skills for operating this CLI, and the installer avoids replacing unmanaged or modified skill directories.
