AI Security Review
scanned 21d ago · by lpm-firewall-aiThe package has a guarded agent configuration lifecycle: explicit setup is followed by automatic refresh of saved wiring on later session starts. The postinstall hook records package-aligned telemetry, and the inspected source does not establish a concrete attack warranting a block.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A user runs the init command; later, a Claude session starts with a version mismatch.
Impact
Agent configuration owned by this package can be rewritten during session startup, including shared Claude configuration when global setup was selected. No concrete malicious behavior was identified.
Mechanism
The setup records selected hosts and options, then refreshes their wiring from those saved choices. Claude setup writes project settings and helpers and can install a global Claude configuration.
AI rationale
The package has a guarded agent configuration lifecycle: explicit setup is followed by automatic refresh of saved wiring on later session starts. The postinstall hook records package-aligned telemetry, and the inspected source does not establish a concrete attack warranting a block.

Decision evidence
public snapshotAI called this Suspicious at 79.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The manifest runs a postinstall hook that records an install event; the telemetry gate is default-on unless disabled or CI is detected, and the sender uses the package-aligned Nanonets endpoint.
- The CLI exposes an explicit init command that writes selected agent wiring; Claude setup includes project settings and helper files and can add a global Claude configuration.
- On later session starts, a version mismatch can trigger a refresh that replays the hosts and options saved by init.
- The five targeted source locations show repo-scoped ignore and brand checks, exclusion of personal Claude files from note targets, repo-local trail documentation, and named Claude wiring destinations.
Evidence against
- The inspected postinstall path records telemetry and starts its flush flow; agent configuration setup is performed through init and subsequent refreshes replay its saved choices.
