domma-js@0.39.1
Dynamic Object Manipulation & Modeling API - A complete front-end toolkit.
AI Security Review
scanned 11d ago · by lpm-firewall-aiThe malicious scanner label is not supported by the inspected source. The install-time agent setup remains a guarded lifecycle capability, so warn rather than block.
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, then accepting the postinstall prompt.
Impact
A user-approved setup can add project-level agent guidance and settings. No credential exposure or other attack effect was identified.
Mechanism
The hook copies CLAUDE.md and related setup files when destinations are absent; the CLI provides a separate confirmed setup command.
AI rationale
The malicious scanner label is not supported by the inspected source. The install-time agent setup remains a guarded lifecycle capability, so warn rather than block.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package runs bin/postinstall.js during npm installation.
- The postinstall hook offers to copy package-provided Claude Code files after prompting, and copies CLAUDE.md only when the destination does not already exist.
- The CLI also copies these files only after an explicit setup command and confirmation.
- The flagged view template contains ordinary lifecycle logging and a commented example request; it does not establish malicious behavior.
Evidence against
- The postinstall hook skips development and CI contexts and requires an installation under node_modules.
- No credential collection, data transmission, or destructive behavior was identified in the inspected lifecycle and agent setup code.
