Reason CLI native binary for linux-x64

AI Security Review

scanned 4d ago · by lpm-firewall-ai

The manifest has no install lifecycle hook, and the inspected JavaScript includes a project skill-copy helper. Manual review is warranted because the bundled native executable’s behavior remains materially unresolved; no attack is established by the available source evidence.

Static reason

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

Trigger

Running the bundled CLI would activate the native executable; its internal activation paths could not be resolved from the available analysis.

Impact

Potential native behavior cannot be assessed from the inspected evidence.

Mechanism

The supplied offline analysis exposes bounded embedded source windows but cannot establish loader reachability or the absence of other native behavior.

AI rationale

Evidence

.lpm-inspection-giata1/0-b1eb4fefe89c.txtbin/reason

Decision evidence

public snapshot

AI called this Manual Review at 81.0% confidence as Unknown with medium false-positive risk.

AI review observations

package.json identifies this as the Linux x64 native CLI package; its inspected manifest has no lifecycle script.
The bundled Playwright trace helper copies a skill into the current project’s .claude/skills directory when invoked.
The native executable analysis contains only bounded embedded source windows and says they cannot establish loader reachability or rule out other native behavior.

Evidence against

The inspected sources do not establish a concrete attack or credential transfer.
