AI Security Review

scanned 2d ago · by lpm-firewall-ai

No confirmed malicious attack surface is established in this package source. The executable is a user-invoked shim that delegates to an exact-version optional platform package rather than running at install/import time.

Static reason
One or more suspicious static signals were detected.
Trigger
User runs the mastercoder CLI
Impact
Executes the selected optional dependency binary with user-provided CLI arguments
Mechanism
platform-specific binary launcher via spawnSync
Rationale
The scanner findings map to a conventional CLI launcher pattern with no lifecycle execution, persistence, exfiltration, or AI-agent control-surface mutation in the inspected source. The README/package mismatch and opaque optional dependency delegation are quality/supply-chain concerns, but this package version's direct source does not show concrete malicious behavior.
Evidence

Decision evidence

public snapshot
AI called this Clean at 83.0% confidence as Benign with low false-positive risk.
Evidence for block
  • bin/mastercoder.mjs uses child_process.spawnSync to run a platform optional dependency binary
  • README.md is for opencode rather than mastercoder, suggesting packaging/documentation mismatch
Evidence against
  • package.json has no preinstall/install/postinstall lifecycle scripts
  • bin/mastercoder.mjs only resolves mastercoder-${platform}-${arch}/bin/mastercoder and forwards CLI args/stdio
  • No source code writes files, reads env/secrets, mutates agent configs, or performs network requests
  • Only three package files are present: package.json, README.md, bin/mastercoder.mjs
