domma-js@0.52.2
Dynamic Object Manipulation & Modeling API - A complete front-end toolkit.
AI Security Review
scanned 8d ago · by lpm-firewall-aiThe postinstall hook can change project-level Claude configuration without requiring an explicit affirmative response. Its scope is limited to missing project files, and the inspected content is framework guidance, so the evidence supports a warning rather than a block.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review
Trigger
Dependency installation runs the postinstall hook from within node_modules outside CI.
Impact
The package changes the project context Claude Code may use. The inspected settings contain Domma framework preferences, with no evidence of permission grants or telemetry.
Mechanism
The hook copies its bundled CLAUDE.md and .claude directory into the project when those destinations are absent; only n or no declines.
AI rationale
The postinstall hook can change project-level Claude configuration without requiring an explicit affirmative response. Its scope is limited to missing project files, and the inspected content is framework guidance, so the evidence supports a warning rather than a block.

Decision evidence
public snapshotAI called this Suspicious at 85.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json runs bin/postinstall.js after dependency installation.
- The hook skips CI and development contexts, and proceeds only when its working directory is inside node_modules.
- The install prompt accepts any response except n or no, so an empty response continues to the copy step.
- The hook copies its bundled CLAUDE.md and .claude directory into the project only when those destinations do not already exist.
- The bundled Claude settings contain Domma-specific framework preferences and documentation paths.
- The separate setup-ai command also copies these files after asking the user whether to continue.
Evidence against
- The installer preserves existing CLAUDE.md and .claude destinations; the inspected settings are project guidance, not tool permission grants or telemetry configuration.
