devez-vibe@1.10.1

Stable terminal UI for Codex and Claude Agent SDK

AI Security Review

scanned 9d ago · by lpm-firewall-ai

The automatic postinstall setup modifies user-level agent skill directories, which warrants a warning for first-party agent extension setup. The inspected bridge settings path is request-dispatched, and the flagged benchmark file is a test harness; neither establishes a separate malicious behavior.

Static reason

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

Trigger

Installing the npm package runs its postinstall hook.

Impact

The package changes which skills are available to the user's agents and can remove older files within the two managed skill folders.

Mechanism

The hook invokes a script that copies the bundled skill trees into both agent skill directories and prunes stale entries within those skill folders.

AI rationale

Evidence

package.jsoninstall-skills.mjs

Decision evidence

public snapshot

AI called this Suspicious at 87.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The manifest runs the skill installer automatically during postinstall.
The installer targets user-level Codex and Claude skill directories.
It copies bundled skills into those directories and prunes entries missing from the bundled versions.
The flagged Claude settings path is part of a permissions update handled through bridge RPC dispatch, not the postinstall installer.
The flagged Python file is identified in source as a before-and-after benchmark harness.

Evidence against

The bridge permission handler changes Claude permission rules in a selected settings scope; the inspected path does not enable agent content telemetry or install plugins.
The benchmark finding is in a test harness rather than an install entrypoint.
