AI Security Review

scanned 2d ago · by lpm-firewall-ai

No confirmed malicious attack surface in the inspected source. The package is a thin user-invoked CLI launcher for a platform-specific optional dependency binary.

Static reason
One or more suspicious static signals were detected.
Trigger
user runs the mastercoder CLI
Impact
Executes the package-aligned optional dependency binary with inherited stdio; no install-time or import-time action found in this package source.
Mechanism
platform binary resolution and spawnSync passthrough
Rationale
The suspicious child_process signal is package-aligned launcher behavior and only runs when the user invokes the CLI. Static inspection found no lifecycle hook, exfiltration, persistence, destructive behavior, or unconsented AI-agent control-surface mutation in this package.
Evidence

Decision evidence

public snapshot
AI called this Clean at 86.0% confidence as Benign with low false-positive risk.
Evidence for block
  • bin/mastercoder.mjs uses spawnSync to execute a platform optional-dependency binary
  • package.json declares optional platform packages mastercoder-<os>-<arch>
Evidence against
  • package.json has no lifecycle scripts
  • bin/mastercoder.mjs only resolves mastercoder-${platform}-${arch}/bin/mastercoder and forwards CLI args on user invocation
  • No source writes to home/project agent control surfaces, shell startup files, VCS hooks, or persistence paths
  • No credential/env harvesting, network calls, eval/vm/Function, or dynamic remote code loading found
  • README contains opencode documentation mismatch but no executable package behavior
