AI Security Review
scanned 11d ago · by lpm-firewall-aiThe package has a postinstall hook that offers setup of package-owned AI assistance files in the consumer project. The inspected prompt and file-copy guards support a warning for guarded agent setup, not a confirmed attack.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Installing the package in a node_modules context outside CI, followed by accepting the postinstall prompt.
Impact
Accepted setup adds package-provided AI assistance configuration and guidance to the project.
Mechanism
The hook prompts the user, then copies files from its kickstart template into the project when destination files are absent.
AI rationale
The package has a postinstall hook that offers setup of package-owned AI assistance files in the consumer project. The inspected prompt and file-copy guards support a warning for guarded agent setup, not a confirmed attack.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json runs bin/postinstall.js during installation.
- The postinstall script asks whether to copy AI assistance files and allows the user to decline.
- After the prompt, the postinstall script copies a CLAUDE.md file into the project only if one is not already present.
- The CLI's setup-ai command also prompts before copying its CLAUDE.md file and skips it if it already exists.
- The flagged view template contains a logging example and a commented-out data-fetch example.
Evidence against
- The inspected setup behavior is limited to adding package-provided AI assistance files; the CLI setup is user-invoked and prompts before copying.
- The inspected template contains no active network or credential handling.
