AI Security Review

scanned 1mo ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. Installing the package drops KORAINIT.md into the consuming project. That file instructs any coding agent that reads it to rewrite broad agent instruction files and can lead to executable Claude hook registration.

Static reason

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

Trigger

npm installation runs postinstall; a coding agent subsequently reads the planted KORAINIT.md.

Impact

Consumer repositories can gain package-controlled instructions in AGENTS.md, CLAUDE.md, and other agent files, plus command hooks in .claude/settings.json.

Mechanism

Postinstall-planted agent instructions drive persistent AI-agent control-surface changes.

Policy narrative

The postinstall hook writes KORAINIT.md into the consumer project without consent. The planted file directly addresses coding agents and tells them to execute koragraph commands. Its prescribed sync operation writes managed content to AGENTS.md and other agent instruction files, and the package includes code to register executable hooks in a target repository's Claude settings. This is an install-driven path from a consumer project mutation to persistent control of broad AI-agent instruction and hook surfaces.

AI rationale

This is unconsented postinstall mutation of a foreign project that plants instructions intended to cause broad AI-agent control-surface writes. The source establishes the complete install-to-agent-control chain, so it meets the publish-block policy.
