AI Security Review
scanned 2d ago · by lpm-firewall-aiNo confirmed malicious attack surface in this wrapper package. The only executable source is a user-invoked launcher for platform optional dependencies.
Static reason
One or more suspicious static signals were detected.
Trigger
User runs the mastercoder CLI binary.
Impact
Executes the resolved platform package binary with user-supplied arguments; no malicious behavior is present in this package source.
Mechanism
optional dependency binary resolution and spawnSync passthrough
Rationale
Static inspection shows a minimal CLI wrapper with no lifecycle execution and no unconsented file or agent-control-surface mutation. Scanner child_process/runtime-install signals are explained by normal CLI delegation and an error message suggesting reinstall when the platform binary is missing.
Evidence
package.jsonbin/mastercoder.mjsREADME.md
Decision evidence
public snapshotAI called this Clean at 90.0% confidence as Benign with low false-positive risk.
Evidence for block
- README.md appears copied from OpenCode and includes external install instructions, but it is documentation only.
Evidence against
- package.json has no lifecycle scripts, so install does not execute package code.
- bin/mastercoder.mjs is a user-invoked CLI shim resolving a platform optional dependency and execing its bin.
- No credential/env harvesting, file enumeration, persistence, or agent control-surface writes found.
- No eval/vm/Function, dynamic remote code loading, or package-source network calls found.
