@ayorcodes/claudespace@1.0.11

Open a Claude Code multi-pane terminal workspace with one command (macOS only)

AI Security Review

scanned 20d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. npm postinstall runs a bundled compiled binary and syncs this package's prompts, hooks, and templates into the user's Claude Code directories. Those hooks are registered for global PATH use and are described as running on every Claude Code session on the machine.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review

Trigger

npm install of @ayorcodes/claudespace, which runs scripts/postinstall.js

Impact

Claude Code's user-level command and hook surface is changed for every session, not only this package's own workspace.

Mechanism

unconsented postinstall write of Claude Code hooks and commands

Policy narrative

On npm install, postinstall.js requires a global install, then runs a bundled compiled binary as claudespace doctor --yes and as sync-assets. The sync step writes this package's prompts, hooks, and templates into the user's Claude Code and related home directories. Those hooks are meant to run by command name on PATH, and a leftover global Stop hook is described as firing on every Claude Code session on the machine. That is an unconsented install-time change to a foreign, machine-wide agent control surface, not a user-run setup command.

AI rationale

The install script launches a bundled binary and syncs hooks into Claude Code's user directories without a separate setup command. That is unconsented postinstall mutation of a foreign, machine-wide agent control surface, so the package is blocked.
