AI Security Review

scanned 11d ago · by lpm-firewall-ai

Source inspection shows project-scoped agent configuration writes through explicit commands, which warrant a capability warning. The postinstall action is limited to copying a missing guide, and no concrete malicious behavior was established.

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 user runs practice sync or the explicit hooks install command.

Impact

Agent behavior can be influenced by the written instructions and hooks when the configured agent runs.

Mechanism

Practice sync updates agent instruction files; hook installation adds package-owned commands to the project’s Claude Code settings.

AI rationale

Evidence

src/practice/sync.jssrc/services/practice-hooks.jssrc/cli/hooks.js

Decision evidence

public snapshot

AI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The explicit practice sync command can write agent instruction files, including an AGENTS.md file created even when absent.
The package offers a command that adds its own hooks to a project’s Claude Code settings.
The postinstall hook only copies a missing KORAINIT.md into the project root.

Evidence against

Claude hook installation and removal are selected by an explicit CLI verb.
No package network endpoint or confirmed credential exfiltration was identified in the inspected source.
