devez-vibe@1.10.6

Stable terminal UI for Codex and Claude Agent SDK

AI Security Review

scanned 6d ago · by lpm-firewall-ai

The postinstall hook performs first-party setup of skills in global agent directories, which leaves a concrete agent-extension lifecycle risk and merits a warning. The inspected skill text and bridge behavior do not establish a concrete attack or justify blocking publication.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

The npm postinstall hook runs during package installation.

Impact

The installed skills can influence later agent behavior when selected or invoked; the source inspected here does not show credential theft or an unconsented settings change.

Mechanism

The hook copies bundled skill files into user-level agent skill folders and removes destination entries absent from the package.

AI rationale

Evidence

package.jsoninstall-skills.mjsskills/luna-loop/SKILL.mdskills/insane-search/SKILL.mdbridge/claude-agent-sdk-bridge.mjs

Decision evidence

public snapshot

AI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The postinstall hook automatically runs the skill installer and dependency preparer.
The installer copies and prunes bundled skills in the user’s Codex and Claude skill directories.
The installed skills direct agents to run bundled workflows, including an adaptive web-fetch tool.
The Luna skill says to use it only when the user directly invokes it; the bridge exposes permission updates through a runtime request handler.

Evidence against

The inspected bridge permission-setting path is a runtime operation, not part of the postinstall installer.
The bundled Luna skill specifies direct user invocation as its activation condition.
