Code Relax Windows, macOS and Linux workstation service

AI Security Review

scanned 6d ago · by lpm-firewall-ai

The postinstall hook causes persistent service setup and installs a first-party agent skill during global installation, creating an agent-extension lifecycle risk. The inspected skill and runtime behavior are package-aligned, with no concrete malicious action established.

Static reason

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

Trigger

Global npm installation invokes the package’s postinstall hook.

Impact

The service persists across logins and the package adds instructions to the user’s agent environment without a separate setup prompt.

Mechanism

The hook runs setup; setup enables login startup and writes the package-owned skill under the user’s 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 91.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The manifest registers a postinstall hook that runs the package’s setup command during global installation.
The hook is gated on direct invocation and a global npm install, then runs setup and doctor.
Setup enables login startup for the service and installs the package’s own Codex skill in the user’s agent skills directory.
The installer refuses to overwrite an unmanaged or modified skill, then writes the package skill and an ownership marker.
The skill describes Code Relax setup and mobile-message workflows, consistent with the package’s stated product.
The inspected messaging connection announces background presence and subscribes to its configured topic; its authenticated HTTP/2 client targets chatgpt.com.
The message-send path takes its prompt from the supplied request arguments; no publisher-selected account change was identified in the inspected paths.

Evidence against

The postinstall behavior is limited to global installs, and the skill is package-owned and product-specific.
The runtime citation locations resolve to connection setup and topic subscription; the inspected messaging path uses the intended ChatGPT host and caller-provided message content.
