AI Security Review

scanned 3d ago · by lpm-firewall-ai

No confirmed malicious attack surface is established in this package source. The package is a thin user-invoked CLI launcher for platform-specific optional dependencies.

Static reason
One or more suspicious static signals were detected.
Trigger
User runs the mastercoder CLI.
Impact
Runs the selected MasterCoder platform binary with inherited stdio; no source-level exfiltration or persistence observed here.
Mechanism
require.resolve plus spawnSync of package-aligned optional dependency binary
Rationale
Static inspection shows a package-aligned CLI shim with no lifecycle hooks and no source evidence of unconsented install-time mutation, exfiltration, or persistence. The child_process use is expected for a binary launcher and only occurs when the user invokes the CLI.

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 invokes a platform-specific optional dependency binary with full stdio passthrough when the CLI is run.
  • README.md appears copied from opencode and documents curl-based install commands, but it is inert documentation in this package.
Evidence against
  • package.json defines no npm lifecycle scripts, so there is no install-time execution.
  • bin/mastercoder.mjs only resolves mastercoder-${platform}-${arch}/bin/mastercoder and spawnSyncs it with user CLI args.
  • No credential/env harvesting, file writes, persistence, AI-agent control-surface mutation, or network code found in package source.
  • The scanner runtime install finding is an error-message suggestion, not an executed package-manager command.
