AI Security Review
scanned 11d ago · by lpm-firewall-aiThe postinstall hook can add package-provided Claude files to the consumer project after a prompt, with Enter accepting the default yes. This supports a warning for guarded agent integration lifecycle risk, not a confirmed malicious attack.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Installing the package through npm, followed by accepting the postinstall prompt; alternatively, explicitly running the setup-ai CLI command.
Impact
Accepted setup adds package-provided files to the project's Claude configuration surface.
Mechanism
The hook copies Claude-related files into the project when the user accepts and destination files do not already exist.
AI rationale
The postinstall hook can add package-provided Claude files to the consumer project after a prompt, with Enter accepting the default yes. This supports a warning for guarded agent integration lifecycle risk, not a confirmed malicious attack.

Decision evidence
public snapshotAI called this Suspicious at 89.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package runs bin/postinstall.js during npm postinstall.
- The postinstall hook asks whether to copy AI assistance files; its prompt defaults to yes.
- After acceptance, the hook can create CLAUDE.md in the consuming project.
- The CLI also exposes an explicit setup-ai command that copies Claude-related files.
Evidence against
- The postinstall hook skips CI and only runs from a node_modules installation context.
- The source inspected shows a consent prompt and copies files only when their destinations do not already exist.
