devez-vibe@1.9.33

Stable terminal UI for Codex and Claude Agent SDK

AI Security Review

scanned 11d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. Installing the package runs a postinstall script that writes this package's agent skills into both the Codex and Claude user skill directories. The copy replaces those skill folders and removes files that are not part of the bundle.

Static reason

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

Trigger

npm postinstall during package installation, with no separate user command.

Impact

Codex and Claude load package-supplied skill instructions from the user skill directories without an install-time consent step, and prior content in those two skill folders can be deleted.

Mechanism

install-skills.mjs resolves the Codex and Claude home directories, copies luna-loop and insane-search into each skills folder, prunes extras, and writes a bundled marker.

Policy narrative

On npm install, postinstall launches install-skills.mjs. The script targets the user Codex skills directory and the user Claude skills directory, copying the bundled luna-loop and insane-search trees into both. It then deletes files in those destinations that are not in the bundle and drops a marker file. No prompt gates the write, so both agent products pick up this package's skill instructions from their user control surfaces.

AI rationale

The postinstall hook unconditionally mutates two foreign user-level agent skill directories, which is an unconsented broad AI-agent control-surface write. The same script also deletes non-bundled files inside those skill folders.
