The package declares the resulting application entrypoints owned and subject to restoration by its build plugin. - **Trigger:** npm installation runs the postinstall lifecycle hook in a project with src/. - **Impact:** Existing application styles and entrypoints can be overwritten, build configuration and dependencies changed, and AI coding agents directed by package-authored rules. - **Evidence paths:** package.json, scripts/postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-04T03:43:45.535Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install-time consumer-project and AI-agent control-surface mutation. - **Attack narrative:** On npm installation, the postinstall script locates the consuming project, clears CSS, replaces App.tsx and main.tsx, adds dependencies and a Vite plugin, and writes GEMINI.md and AGENTS.md. The installed plugin is designed to keep those entrypoints canonical, making the package persistently control the consumer application and its AI-agent instructions without an explicit setup command. - **Rationale:** This is an unconsented postinstall mutation of both a broad consumer project and AI-agent control surfaces. The behavior is concrete and automatic, so it meets the install-hook abuse blocking threshold. - **Files touched:** src/index.css, src/App.css, src/main.tsx, GEMINI.md, AGENTS.md, package.json, vite.config.ts, .env ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The automatic postinstall hook rewrites consumer source files and styles., It installs a build plugin that preserves package-owned consumer entrypoints., It creates or refreshes root AI-agent instruction files without user action., It modifies the consumer manifest and Vite configuration during installation. - **Evidence against:** No secret harvesting, shell execution, or network exfiltration was found in the inspected installer. ## Public findings ### 1.
