AI Security Review
scanned 26d ago · by lpm-firewall-aiThe inspected preinstall hook only checks the Node version, and the flagged project writes are scoped to explicit `/init` use. The scanner’s gated-behavior hint was not substantiated by the inspected launcher and CLI excerpts.
Static reason
One or more suspicious static signals were detected.
Trigger
Package installation runs the Node version check; a user can invoke `/init` in a project.
Impact
No unconsented data access, exfiltration, or hostile modification was established.
Mechanism
The preinstall script checks the runtime version. `/init` creates notes directories and writes template files only when they do not already exist.
AI rationale
The inspected preinstall hook only checks the Node version, and the flagged project writes are scoped to explicit `/init` use. The scanner’s gated-behavior hint was not substantiated by the inspected launcher and CLI excerpts.
Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The preinstall hook runs a Node version check.
- The flagged project path is part of the explicit `/init` command, which resolves files under the current project directory.
- The launcher loads the CLI entrypoint; `--version` reads the package version.
- The CLI loads a `.env` file from the current working directory when present.
