AI Security Review

scanned 2h ago · by lpm-firewall-ai

No confirmed malicious attack surface in this wrapper package. Runtime behavior is a user-invoked CLI shim that delegates to package-named optional dependency binaries.

Static reason
One or more suspicious static signals were detected.
Trigger
User runs the mastercoder CLI
Impact
Executes the platform-specific MasterCoder binary if installed; wrapper itself does not exfiltrate, persist, or mutate files
Mechanism
platform optional-dependency binary resolution and spawnSync delegation
Rationale
Static inspection shows a narrow CLI launcher with no install-time execution and no concrete malicious behavior in this package. The child_process finding is package-aligned runtime delegation to an optional dependency, while the install command finding is non-executed help text.

Decision evidence

public snapshot
AI called this Clean at 90.0% confidence as Benign with low false-positive risk.
Evidence for block
  • bin/mastercoder.mjs uses spawnSync to execute a platform-specific optional dependency binary
  • README.md appears copied from OpenCode and references opencode.ai rather than mastercoder
Evidence against
  • package.json has no preinstall/install/postinstall or other lifecycle scripts
  • bin/mastercoder.mjs only resolves mastercoder-${platform}-${arch}/bin/mastercoder and passes user CLI args through
  • No credential/env harvesting, file enumeration, persistence, destructive logic, eval/vm/Function, or network calls found
  • Scanner runtime_package_install is only an error message suggesting npm install -g mastercoder --force, not executed code
