AI Security Review
scanned 10d ago · by lpm-firewall-aiThe postinstall hook installs package-owned Claude Code context files unless the user declines, and the CLI provides a prompted setup path. This warrants a warning for guarded agent configuration setup, but the inspected source does not establish malicious behavior or an unconsented broad control-surface mutation.
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
Installing the package in an eligible project and accepting the postinstall prompt; the prompt defaults to proceeding unless the answer is no.
Impact
Adds assistant context and settings to the project, which can influence later coding-agent sessions.
Mechanism
The hook copies CLAUDE.md and, if absent, recursively copies the template .claude directory into the project root. The CLI also offers this through setup-ai after a prompt.
AI rationale
The postinstall hook installs package-owned Claude Code context files unless the user declines, and the CLI provides a prompted setup path. This warrants a warning for guarded agent configuration setup, but the inspected source does not establish malicious behavior or an unconsented broad control-surface mutation.

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 as an npm postinstall hook.
- The hook prompts before copying; answering no skips setup, while other answers proceed.
- When the project lacks a .claude directory, the hook recursively copies the package template into the project root.
- The CLI setup-ai command also prompts before copying assistant files and avoids replacing existing destinations.
- The inspected Claude settings contain Domma project paths and coding preferences.
Evidence against
- The postinstall hook skips CI environments and offers the user a chance to decline.
- The copied settings appear to provide framework guidance; the inspected excerpts show no credential transfer, remote execution, or permission changes.
