devez-vibe@1.9.35

Stable terminal UI for Codex and Claude Agent SDK

AI Security Review

scanned 24d ago · by lpm-firewall-ai

The automatic cross-agent skill installation and user-level pip mutation create a guarded agent-extension lifecycle risk. The inspected source does not establish a concrete malicious attack, so blocking is not supported.

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

Installing the package through npm runs postinstall.

Impact

The package can persist its own skills in two AI-agent environments and alter the user's Python package environment without a separate setup command.

Mechanism

The hook copies and prunes bundled skills in agent skill directories, then conditionally runs pip with a user installation target.

AI rationale

Evidence

package.jsoninstall-skills.mjsprepare-search-deps.mjsskills/luna-loopskills/insane-search

Decision evidence

public snapshot

AI called this Suspicious at 91.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

The manifest automatically runs the skill installer and dependency preparer after npm installation.
The installer targets Codex and Claude skill directories under the user's configuration homes and copies, prunes, and marks two bundled skill directories.
The same automatic lifecycle chain invokes a user-level pip installation when its Python dependency check fails.
Claude permission updates are exposed through a bridge function and default to project settings; this behavior is separate from the install hook.

Evidence against

No inspected source showed secret collection, credential forwarding, remote payload retrieval, or hidden network exfiltration.
The installed agent content is limited to package-named skill directories rather than arbitrary agent configuration files.
