Reason CLI native binary for linux-arm64-musl

AI Security Review

scanned 4d ago · by lpm-firewall-ai

The package manifest has no install hook, and the inspected project skill installation requires an explicit CLI command. The required native executable remains materially unresolved, so the evidence does not support a clean or malicious verdict.

Static reason

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

Trigger

Execution of bin/reason; its relevant behavior could not be determined from the available analysis.

Impact

Unknown until the native executable’s behavior is adequately analyzed.

Mechanism

The executable is an 83 MB ELF binary, and the inspected analysis provides bounded embedded-source candidates without proving full loader reachability or excluding other behavior.

AI rationale

Evidence

bin/reason.lpm-inspection-nXYv6K/0-916c16479235.txt

Decision evidence

public snapshot

AI called this Manual Review at 96.0% confidence as Unknown with medium false-positive risk.

AI review observations

The manifest declares package identity and platform metadata but no install lifecycle script; it packages the executable under bin.
The Playwright skill copy is exposed through an explicit install-skill CLI command and writes under the current project’s .claude/skills directory.
The native executable’s offline analysis is limited to embedded source candidates and cannot establish its full behavior.

Evidence against

The inspected skill installation is user-invoked, not an automatic install hook.
