AI coding skills that auto-sync across Claude Code, Cursor, Gemini CLI, and Codex CLI

AI Security Review

scanned 2d ago · by lpm-firewall-ai

The postinstall path automatically modifies user-level Codex hooks and instructions before asking the user to review the hooks. The source shows first-party CraftKit integration, so this is a lifecycle setup risk rather than confirmed malicious behavior.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

Installing the npm package, which invokes its postinstall hook.

Impact

CraftKit hooks and instructions can affect Codex sessions across projects; the user is asked to review and trust the hooks only after registration.

Mechanism

The hook runs sync.sh, whose Codex adapter copies hook scripts, registers them across five Codex events, and updates the managed AGENTS.md section.

Decision evidence

public snapshot

AI called this Suspicious at 89.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The package runs scripts/postinstall.sh during installation.
That hook runs sync.sh without the interactive configuration option; the checklist only runs with --configure, and postinstall cannot prompt when no terminal is available.
The Codex adapter copies CraftKit hooks into the user-level Codex hooks directory and registers them for SessionStart, UserPromptSubmit, PreToolUse, PostToolUse, and Stop.
When no matching hook exists, the adapter adds one to hooks.json and writes the updated configuration.
The adapter also adds or updates a managed CraftKit section in the user-level Codex AGENTS.md.
The installed Codex hook injects applicable CraftKit rules into session context.

Evidence against

These are CraftKit-owned hooks and instructions, and the adapter preserves unrelated hook entries.
The adapter reports that the hooks were registered and tells the user to review and trust them after registration.
