Reason CLI native binary for linux-arm64

AI Security Review

scanned 4d ago · by lpm-firewall-ai

The inspected agent-related behavior is consistent with file-search exclusions and an explicit workspace skill setup command. The native executable analyses leave material behavior unresolved, so the source evidence does not support either a clean verdict or a confirmed attack.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

Use of the packaged native executable; its behavior could not be assessed from the available offline analyses.

Impact

The unresolved native behavior prevents a reliable clean verdict; no specific malicious effect was verified.

Mechanism

The main executable analysis covers bounded embedded source candidates, while the separate seccomp executable is an unrecognized artifact.

Decision evidence

public snapshot

AI called this Manual Review at 94.0% confidence as Unknown with medium false-positive risk.

AI review observations

package.json identifies this as a Linux ARM64 native-binary package and declares no lifecycle scripts.
The sandbox runtime’s cited agent-related location lists configuration paths used by its file-search behavior.
The bundled CLI copies a Playwright trace skill into the project’s Claude skills directory; workspace initialization is an explicit CLI action.
The native executable analysis is limited to embedded source candidates, and the seccomp executable has no supported structural or executable analysis.
