AI Security Review

scanned 5d ago · by lpm-firewall-ai

The manifest has no install lifecycle scripts, and the inspected flagged source does not establish credential exfiltration or a reverse shell. The dynamic Function match is used in a caught feature check, so the scanner hints do not support a malicious verdict.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

The CLI runs when invoked by the user; no install-time trigger is declared.

Impact

No confirmed attack impact was established.

Mechanism

The inspected source dispatches CLI commands and reads Claude configuration settings; no malicious execution or credential transfer was established.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 78.0% confidence as Benign with medium false-positive risk.

Evidence for AI clean decision

package.json declares a CLI entrypoint and dependencies but no install lifecycle scripts.
dist/bin.mjs dispatches CLI commands only when the module is the process entrypoint.
The flagged worker location reads Claude configuration directory settings and compares paths.
The worker’s new Function use is inside a try/catch feature check that returns a boolean.
The other required files are Effect and schema library bundles, a client asset bundle, and an MCP response parser.
