AI Security Review
scanned 11d ago · by lpm-firewall-aiThe install hook can write package-owned assistant configuration into a consumer project, and its prompt defaults to proceeding, leaving meaningful consent risk. The prompt and destination checks make this a warning-level agent extension lifecycle risk rather than a confirmed attack.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
An eligible package installation runs the postinstall hook, which prompts the user; an empty response proceeds with the default affirmative choice.
Impact
The setup can introduce project-level assistant instructions and configuration. No network endpoint or credential transfer was identified in the inspected behavior.
Mechanism
The hook copies CLAUDE.md, .claude/, and other assistance files from the package into the project root when those destinations do not already exist.
AI rationale
The install hook can write package-owned assistant configuration into a consumer project, and its prompt defaults to proceeding, leaving meaningful consent risk. The prompt and destination checks make this a warning-level agent extension lifecycle risk rather than a confirmed attack.

Decision evidence
public snapshotAI called this Suspicious at 92.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json runs bin/postinstall.js during installation.
- The postinstall hook runs in eligible node_modules installs and skips development and CI contexts.
- The hook asks whether to copy AI assistance files; only an explicit “n” or “no” declines, so an empty response proceeds.
- The hook copies package-provided files into the consumer project, including CLAUDE.md and .claude/.
- The CLI also offers an interactive setup command that copies AI assistance files into the current project.
- The indicated view template contains ordinary view lifecycle examples, not install-time behavior.
Evidence against
- The postinstall hook checks its install context and requires an interactive prompt before copying files.
- Copies are limited to files and directories that do not already exist; inspected sources show no network transmission or credential handling.
