Code Relax Windows, macOS and Linux workstation service

AI Security Review

scanned 6d ago · by lpm-firewall-ai

The postinstall hook is limited to global npm installation but then automatically invokes setup, which installs a per-user Code Relax skill. Its package-specific path and ownership checks bound the effect, and inspected runtime behavior did not establish broader agent control or an unrelated credential recipient; warn rather than block.

Static reason

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

Trigger

Installing the package globally through npm triggers its postinstall setup.

Impact

The skill becomes available to guide future agent interactions about Code Relax; no broader agent settings change or malicious account action was established.

Mechanism

Setup installs the package's skill under the user's agent skills directory without a separate skill-install command.

Decision evidence

public snapshot

AI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The manifest defines a postinstall hook that runs tools/postinstall.mjs.
The hook runs setup only for a direct global npm install, then invokes the package CLI setup command.
Setup installs the package-owned Code Relax skill into the user's agent skill directory.
The runtime references show a WebSocket-open background-presence connection and topic subscription; the Celsius connection is requested from ChatGPT.
The runtime HTTP/2 request sends its auth headers to chatgpt.com, consistent with intended-service messaging.

Evidence against

The skill is scoped to ~/.agents/skills/code-relax, and the installer refuses to overwrite a same-name skill it does not manage.
The inspected runtime account behavior is background presence and messaging connectivity; no separate account action or unrelated credential recipient was established.
