AI Security Review

scanned 5h ago · by lpm-firewall-ai

No confirmed malicious attack surface is established in this package source. The package is a CLI shim that delegates to a package-aligned optional dependency at user invocation time.

Static reason
One or more suspicious static signals were detected.
Trigger
User runs the mastercoder CLI binary.
Impact
Executes the resolved platform-specific mastercoder optional dependency with supplied CLI arguments.
Mechanism
platform binary launcher via child_process.spawnSync without shell
Rationale
Static inspection shows no install-time execution, exfiltration, destructive behavior, persistence, or broad AI-agent control-surface mutation. The child_process finding is explained by a normal CLI launcher for package-aligned optional platform binaries.
Evidence
package.jsonbin/mastercoder.mjsREADME.md

Decision evidence

public snapshot
AI called this Clean at 86.0% confidence as Benign with low false-positive risk.
Evidence for block
  • README.md appears copied from opencode and contains opencode install URLs, but it is documentation only.
Evidence against
  • package.json has no preinstall/install/postinstall or other lifecycle scripts.
  • package.json exposes only bin/mastercoder.mjs and platform-specific optionalDependencies.
  • bin/mastercoder.mjs resolves mastercoder-${platform}-${arch}/bin/mastercoder and runs it only when the CLI is invoked.
  • bin/mastercoder.mjs passes user CLI args through spawnSync with stdio inherit; no shell option is used.
  • No credential/env harvesting, file writes, eval/vm, network calls, or agent config mutation found in package source.
