AI Security Review

scanned 22h ago · by lpm-firewall-ai

The global postinstall setup installs a first-party agent Skill that can influence later sessions, which warrants a warning under the extension lifecycle policy. The inspected source does not establish a concrete attack or broad control-surface 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

A global npm installation invokes the package’s postinstall hook.

Impact

The Skill becomes available to affect later agent sessions.

Mechanism

The hook runs setup, which writes the package’s Skill into the user’s agent skills directory.

AI rationale

Evidence

~/.agents/skills/code-relax/SKILL.md~/.agents/skills/code-relax/.code-relax-install.json

Decision evidence

public snapshot

AI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The package declares a postinstall hook, and its script runs setup only when invoked directly during a global npm installation.
Setup installs the package’s Skill in the user’s agent skills directory, where it can affect later agent sessions.
The room client uses the local service’s authentication status and parses server-sent event data; the inspected runtime operation does not establish an unrelated account action.

Evidence against

The installer refuses to replace a same-name Skill unless it is package-managed and unchanged.
The included Skill describes Code Relax service and phone interaction guidance.
