AI Security Review
scanned 11d ago · by lpm-firewall-aiThe scanner’s control-hijack hint is not supported by the inspected template: it contains Domma project preferences and guidance, with no agent hooks or remote skill channel. Because an npm install can invoke a postinstall flow that adds Claude configuration after a prompt, classify this as a warning-level agent extension lifecycle risk.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
npm installation invokes the postinstall hook; the hook reaches its copy step after the prompt unless the response is “n” or “no”.
Impact
It can add package-authored guidance and Domma project preferences used by Claude Code. No agent execution hooks, credential access, or network behavior were found in the inspected configuration.
Mechanism
The hook copies CLAUDE.md and .claude files from the package template into project paths that do not already exist. The CLI exposes a separate interactive setup-ai command for the same files.

Decision evidence
public snapshotAI called this Suspicious at 87.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json runs bin/postinstall.js automatically after installation.
- The postinstall hook prompts before copying files, and an explicit “n” skips the operation.
- The hook copies first-party CLAUDE.md and .claude files only when the corresponding project paths do not already exist.
- The CLI routes setup-ai to an interactive handler that asks whether to continue before copying the same files.
- The supplied .claude settings contain Domma project preferences and style guidance; no agent hooks or remote skill channel are present in the inspected settings.
- templates/view-template/view.js contains only placeholder view callbacks and an example commented-out request.
Evidence against
- The inspected lifecycle and template source shows no credential collection, network transmission, destructive action, or remote code execution.
