AI Security Review

scanned 6d ago · by lpm-firewall-ai

The global postinstall automatically adds a package-owned agent Skill, which warrants a warning for agent extension lifecycle risk. The flagged Celsius behavior is a connection and product-topic subscription, not evidence of an unrelated account action or credential transfer.

Static reason

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

Trigger

A global npm installation invokes the package postinstall hook.

Impact

The package adds its Skill to the user's agent skills directory during installation, without a separate Skill installation command.

Mechanism

The hook starts the CLI setup flow, which installs the bundled Skill under the user's home directory.

AI rationale

Evidence

package.jsontools/postinstall.mjsdist/bin/codex-remote.mjsdist/src/skill-install.mjs

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 runs a postinstall hook, and the hook proceeds only when invoked directly during a global npm install.
The global setup path installs the package Skill from its bundled file; the installer targets the user's agent skills directory.
The Celsius client connects with background presence and subscribes to its configured topics; the Dots client supplies a product messaging topic.
The flagged account-action location is the completion of that topic subscription loop, not an unrelated follow, join, or other account action.

Evidence against

The postinstall hook is gated on a global install.
The Skill is package-owned and installed as part of this package's setup flow.
