AI Security Review
scanned 26d ago · by lpm-firewall-aiSource inspection found no concrete malicious behavior. The lifecycle hook is a version check, and the flagged project configuration writes occur only through an explicit command that preserves existing files.
Static reason
One or more suspicious static signals were detected.
Trigger
Package installation triggers the preinstall version check; a user command triggers project initialization.
Impact
No confirmed harmful effect or attack surface was established.
Mechanism
The version check reports unsupported Node versions and exits. The init command creates project notes and template files only when they are absent.
AI rationale
Source inspection found no concrete malicious behavior. The lifecycle hook is a version check, and the flagged project configuration writes occur only through an explicit command that preserves existing files.
Decision evidence
public snapshotAI called this Clean at 96.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The preinstall hook only runs a Node version check; it exits when the installed Node version is too old.
- The project init command is user-invoked and targets the current project directory; it creates AGENTS.md only if it does not already exist.
- The CLI entrypoint checks the Node version before importing the bundled CLI.
- The bundled CLI loads a .env file from the working directory when present.
- Hugging Face credentials are attached to requests made by the research tool to its Hugging Face API.
- Telemetry disclosure describes usage and error data and states that prompts, model output, paper content, and tool arguments are not sent.
