AI Security Review
scanned 11d ago · by lpm-firewall-aiThe postinstall hook automatically copies package-owned skill files into the user’s Codex skills directory, creating an agent extension lifecycle risk. The inspected OAuth code follows a local callback PKCE flow, and no concrete malicious behavior was established.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Installing the package through npm, unless the skip environment variable is set or the package is the current working directory.
Impact
The installed skill becomes available to Codex and can guide agent behavior for this package’s CLI.
Mechanism
The postinstall hook calls the skill manager, which copies bundled files into the default Codex skills directory and manages existing skill targets.
AI rationale
The postinstall hook automatically copies package-owned skill files into the user’s Codex skills directory, creating an agent extension lifecycle risk. The inspected OAuth code follows a local callback PKCE flow, and no concrete malicious behavior was established.
Evidence

Decision evidence
public snapshotAI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json runs scripts/postinstall.mjs during installation.
- The postinstall hook normally imports the skill manager and installs bundled skills unless VVICAT_SKIP_SKILL_INSTALL is set or the package is the current working directory.
- The manager’s default Codex destination is under the user’s .codex/skills directory, and it copies bundled skill files there.
- This is package-owned agent skill setup; the inspected code does not show a remote skill channel or credential exfiltration.
Evidence against
- The Google login flow uses OAuth PKCE, opens the provider’s authorization URL, and exchanges the returned code for a session.
- The OAuth callback server listens only on 127.0.0.1.
