Reason CLI native binary for linux-x64-musl

AI Security Review

scanned 4d ago · by lpm-firewall-ai

The manifest has no lifecycle script, and the inspected agent-skill setup is an explicit project initialization action. The native executable is not sufficiently analyzed to establish either benign behavior or an attack, so the package requires manual review.

Static reason

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

Trigger

No malicious trigger was established; the unresolved component is the package’s native executable.

Impact

The executable’s potential impact cannot be determined from the available analysis.

Mechanism

The inspected native analysis exposes embedded-source windows but does not resolve the executable’s full behavior or reachability.

AI rationale

Evidence

.lpm-inspection-uUOGSg/0-b76f10636df5.txt

Decision evidence

public snapshot

AI called this Manual Review at 72.0% confidence as Unknown with medium false-positive risk.

AI review observations

package.json identifies this as the Linux x64 musl Reason CLI native-binary package and contains no lifecycle script.
The Playwright skill installer writes into the current project’s .claude skills directory and is exposed through an explicit initialization option.
The native executable analysis contains only bounded embedded-source windows and says those windows cannot establish the executable’s full behavior.

Evidence against

The inspected JavaScript did not establish a concrete attack.
