AI Security Review
scanned 3d ago · by lpm-firewall-aiThe install hook performs project-level AI configuration setup and treats the displayed yes-default as acceptance, leaving a lifecycle risk. Its inspected templates are package-specific guidance and preferences, so the evidence supports a warning rather than a malicious verdict.
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
An npm install that runs the postinstall hook outside CI, followed by an answer other than `n` or `no` to its `(Y/n)` prompt.
Impact
The added project guidance may influence later Claude Code work. The inspected settings are framework preferences, and the source does not establish permission changes or remote activity.
Mechanism
The hook copies package-owned AI assistance files into the project root when the corresponding destinations are absent; the displayed default makes an empty response proceed.
AI rationale
The install hook performs project-level AI configuration setup and treats the displayed yes-default as acceptance, leaving a lifecycle risk. Its inspected templates are package-specific guidance and preferences, so the evidence supports a warning rather than a malicious verdict.

Decision evidence
public snapshotAI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The manifest runs `bin/postinstall.js` during installation; the hook is limited to normal `node_modules` installs and skips CI and the package's own development tree.
- The hook asks to copy AI assistance files with a `(Y/n)` prompt and proceeds unless the answer is `n` or `no`, so accepting the displayed default copies them.
- The hook copies package-owned `CLAUDE.md` and `.claude` files into the project root only when those destinations do not already exist.
- The inspected templates provide Domma framework guidance and project preferences; the settings shown do not configure agent permissions or plugins.
- The CLI also exposes this setup through an explicit `setup-ai` command and asks whether to continue.
Evidence against
- The inspected setup concerns project-level files and package-specific framework guidance; it does not establish a remote channel or an active attack.
