It does so without an explicit user command. - **Trigger:** A global npm installation invokes postinstall. - **Impact:** It can add commands and skills to Claude Code and leave package services running after installation. - **Evidence paths:** package.json, bin/postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-01T09:56:28.308Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Lifecycle-driven service startup and Claude Code plugin installation. - **Attack narrative:** npm invokes bin/postinstall.js during installation. For a global installation, the script starts the package service and uses the Claude CLI to add a marketplace and install claude-code-multisession. This changes an AI-agent extension surface without an explicit setup command from the user. - **Rationale:** The automatic postinstall performs unconsented mutation of the Claude Code plugin control surface and starts persistent services. This is concrete lifecycle abuse, irrespective of the benign-looking loopback checks and PNG artifact. - **Files touched:** bin/postinstall.js, bin/lm-assist.js - **Network endpoints:** 127.0.0.1 ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The manifest runs a postinstall script automatically., For global installs, the postinstall script starts package services without a user command., The same postinstall script adds a Claude marketplace and installs a Claude Code plugin automatically. - **Evidence against:** The reviewed lifecycle network request is limited to the local loopback service., The PNG finding is an ordinary 512 by 512 PNG image, not an executable payload. ## Public findings ### 1.
