AI Security Review

scanned 2d ago · by lpm-firewall-ai

No confirmed malicious attack surface in this package source. The only executable code is a user-invoked bin launcher for a package-aligned platform binary supplied through optionalDependencies.

Static reason
One or more suspicious static signals were detected.
Trigger
User runs the mastercoder CLI bin
Impact
Executes the resolved mastercoder platform optional-dependency binary with user-supplied CLI arguments
Mechanism
platform binary delegation via spawnSync
Rationale
Static inspection found a package-aligned CLI launcher with no lifecycle execution, persistence, credential access, network behavior, or AI-agent control-surface mutation in this package. The scanner's child_process/runtime install hints are explained by user-invoked platform binary delegation and an error message suggesting npm install, not runtime package installation.

Decision evidence

public snapshot
AI called this Clean at 88.0% confidence as Benign with low false-positive risk.
Evidence for block
  • bin/mastercoder.mjs is a CLI wrapper that spawnSyncs a platform optional-dependency executable when user runs the bin
  • README.md contains OpenCode install URLs, but they are documentation only and not executed by package code
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 through argv/stdio
  • No source writes files, modifies agent configs, persists hooks/services, harvests env/files, or performs network I/O
  • Package contents are limited to package.json, README.md, and bin/mastercoder.mjs
