Lodestar (夜航星) — IM-native frontend for Codex, Claude Agent SDK and DeepSeek Harness via Feishu Card Kit

AI Security Review

scanned 16d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. An npm postinstall hook deletes a named skill from Codex and Claude user control directories. This mutates foreign AI-agent control surfaces during installation without a user command.

Static reason

High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source

Trigger

Installing the package through npm activates postinstall.

Impact

A package installation can remove a user-controlled skill named lodestar-files from Codex or Claude directories.

Mechanism

The hook calls removeManagedSkill, which reads SKILL.md, accepts a matching frontmatter name, and recursively removes the corresponding directory.

Policy narrative

On installation, npm runs the package's postinstall hook. That hook invokes a cleanup routine which searches user-level Codex and Claude skill roots for lodestar-files and recursively deletes each matching directory. The check only verifies that the target SKILL.md declares the same name, so installation mutates external agent configuration areas rather than limiting itself to package-owned files.

AI rationale

This is an unconsented automatic install-time mutation of foreign AI-agent control surfaces. The opt-out and name check do not change that the deletion is triggered by installation.
