AI Security Review
scanned 11d ago · by lpm-firewall-aiThe postinstall hook exposes a guarded, package-owned Claude Code configuration setup capability. The inspected source does not establish unconsented broad control-surface mutation or another concrete attack, so warn rather than block.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
A normal dependency installation reaches the postinstall prompt; answering yes or pressing Enter proceeds with the copy.
Impact
The copied files can affect the project's Claude Code context and settings.
Mechanism
The hook copies CLAUDE.md and related assistance files into project locations when those destinations do not already exist.
AI rationale
The postinstall hook exposes a guarded, package-owned Claude Code configuration setup capability. The inspected source does not establish unconsented broad control-surface mutation or another concrete attack, so warn rather than block.
Evidence

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json runs bin/postinstall.js during installation.
- The postinstall script prompts to copy AI assistance files; declining skips the copy, while blank input proceeds.
- The postinstall copies package-provided CLAUDE.md into the project when that file is absent.
- The CLI also copies CLAUDE.md into the project during its setup flow.
Evidence against
- The postinstall integration is limited to copying package-owned project files and asks before copying.
