Code Relax Windows, macOS and Linux workstation service

AI Security Review

scanned 6d ago · by lpm-firewall-ai

The global-install postinstall automatically deploys the service and installs a package-owned agent skill, which is a first-party agent extension lifecycle risk. The inspected skill preserves authorization boundaries, and the account-related client path does not establish a separate attack.

Static reason

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

Trigger

Installing the package globally with npm.

Impact

The agent receives additional persistent instructions for phone-originated interactions; the inspected skill text says those instructions do not add authorization.

Mechanism

The postinstall hook launches setup, which writes the package-owned skill file into 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 86.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The manifest declares a postinstall hook; the hook runs setup only when invoked directly during a global npm install.
Setup installs this package's skill into the user's agent skills directory, and the installer writes the skill file there.
The skill adds instructions for phone-originated messages and says its source marker does not add authorization.
The inspected Celsius client connects with background presence and subscribes to its configured topic; its Dots task caller uses the client for task file uploads, and the room client obtains local ChatGPT authentication and connects to chatgpt.com.

Evidence against

The skill text preserves normal authorization boundaries, and the inspected account-related path shows service connection and topic subscription rather than an unrelated account change.
