AI Security Review
scanned 2d ago · by lpm-firewall-aiNo confirmed malicious attack surface in this package source. The only executable code is a user-invoked CLI shim that delegates to a platform-specific optional dependency.
Static reason
One or more suspicious static signals were detected.
Trigger
User runs the mastercoder CLI
Impact
Executes the package-aligned platform binary if installed; no source evidence of exfiltration or persistence in this wrapper package.
Mechanism
CLI binary delegation via spawnSync
Rationale
Static inspection shows a thin CLI launcher with no install-time execution and no data theft, persistence, or AI-agent control-surface writes. Scanner findings map to package-aligned child_process use activated only when the user runs the CLI.

Decision evidence
public snapshotAI called this Clean at 90.0% confidence as Benign with low false-positive risk.
Evidence for block
Evidence against
- package.json has no npm lifecycle scripts
- bin/mastercoder.mjs only resolves a platform optional dependency and spawnSyncs its bin on explicit CLI use
- No fs writes, env/credential harvesting, eval/vm, network code, persistence, or agent control-surface mutation found
- README contains OpenCode install/docs links but no package-executed behavior
