It also checks npm and reinstalls the package during that lifecycle path. - **Trigger:** npm install or update of the package as a project dependency - **Impact:** A package installation can activate or replace project-local agent skills and MCP configuration without an explicit setup command. - **Evidence paths:** package.json, bin/postinstall.js, lib/install.js - **Review source:** ai\_review - **Reviewed:** 2026-08-31T11:42:06.970Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall-driven AI-agent configuration overwrite and self-update - **Attack narrative:** The postinstall hook invokes update with JoyCode, Cursor, agent, and version features enabled. That path deletes and replaces skill directories, writes active agent and MCP configuration into consumer-project AI-tool directories, and registers an npx-based MCP entry. It additionally contacts npm and executes npm install for the package. These actions occur on dependency installation rather than through an explicit user setup command. - **Rationale:** This is an unconsented postinstall mutation of broad AI-agent control surfaces in the consuming project, combined with an automatic networked self-update path. The source establishes concrete install-hook abuse even though no secret theft was found. - **Files touched:** .joycode/skills, .joycode/rules, .joycode/agent.json, .joycode/mcp.json, .cursor/skills, .cursor/rules, .cursor/mcp.json, package.json - **Network endpoints:** https://registry.npmjs.org/%40deppon%2Fpm-toolkit/latest ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The manifest runs a postinstall hook., The hook automatically enables JoyCode, Cursor, agent, and version-service installation in the consumer project., Installation overwrites copied skill directories and registers MCP servers in both AI-tool configuration directories., The automatic update path queries npm and runs npm install for this package. - **Evidence against:** The inspected MCP server is a local stdio service for prototype-version operations., No credential harvesting or secret exfiltration was found in the inspected sources. ## Public findings ### 1.
