P4 Code coding agent server and command-line client

AI Security Review

scanned 5d ago · by lpm-firewall-ai

The inspected source did not substantiate the scanner’s attack labels, and the package has no install lifecycle script. The bundled native process-monitor executable is unsupported by the available artifact analysis, leaving material behavior unresolved.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

Terminal process monitoring when the CLI server uses its native telemetry provider.

Impact

The executable’s behavior and any effects beyond process monitoring could not be established from the inspected package source.

Mechanism

The CLI resolves a platform-specific resource-monitor executable and uses its process-table result; the executable was not supported by the offline artifact analysis.

AI rationale

Evidence

dist/resource-monitor/darwin-arm64/t3-resource-monitor.lpm-inspection-iLyHcY/0-6a36765d7c61.txtdist/binCli-IAUzRF0Y.mjs

Decision evidence

public snapshot

AI called this Manual Review at 82.0% confidence as Unknown with medium false-positive risk.

AI review observations

The native resource monitor is used as the terminal process-table provider, but its executable behavior could not be inspected.
The worker’s dynamic-function match is an empty-function capability check; its worker accepts two named Claude history operations.
The manifest identifies a CLI entrypoint and lists no lifecycle script; the runtime target defines P4 MCP and plugin registry schemas.

Evidence against

The scanner’s reverse-shell and credential-exfiltration labels were not confirmed by the inspected source excerpts.
