Code Relax Windows, macOS and Linux workstation service

AI Security Review

scanned 21h ago · by lpm-firewall-ai

The automatic installation of the package-owned agent skill warrants a warning for agent-extension lifecycle risk. The inspected room-client location parses server-sent event data, and the reviewed source excerpts do not establish a concrete attack or broad agent-control abuse.

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, which runs its postinstall script.

Impact

The agent receives package-provided instructions automatically during installation.

Mechanism

The postinstall script invokes setup; setup installs the bundled Code Relax skill by writing its SKILL.md into the agent skills directory.

AI rationale

Evidence

package.jsontools/postinstall.mjsdist/bin/codex-remote.mjsdist/src/skill-install.mjsdist/skills/code-relax/SKILL.md

Decision evidence

public snapshot

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

Evidence for warning

The package manifest runs a postinstall script that invokes setup.
Setup installs the bundled Code Relax skill into the agent skills directory.
The skill installer writes the bundled instructions to the target SKILL.md.
The inspected skill describes using the Code Relax desktop service and replying to mobile messages.
The unresolved room-client operation parses server-sent event data and invokes its callback; the inspected excerpt does not show an unrelated receiver.

Evidence against

The reviewed excerpts establish an automatically installed, package-owned skill, but do not establish broad agent-setting changes or private-content export.
