Project Context

# Cursor AI Rules - NEXTJS
# Generated via DevUtility Hub

## Core Instructions
You are an expert nextjs developer. Follow these rules strictly for every response:

- Use App Router conventions.
- Prefer Server Components where possible.
- Use Tailwind v4 @theme variables for styling.
- Strict TypeScript only.
- Use Lucide React for icons.

## Interaction Protocol
- Always perform a 'Deep Search' of the codebase before suggesting structural changes.
- If a suggested library is not in the 'package.json' or 'requirements.txt', flag it as a dependency addition.
- Use 'Chain of Thought' reasoning for any architectural decisions.

## Formatting
- Use concise, professional language.
- Provide full, copy-pasteable code blocks.
- Highlight breaking changes with a '⚠️ WARNING' prefix.

How to Deploy to Cursor AI

1

Create File

In your project root, create a file named .cursorrules.

2

Paste Rules

Paste the generated Markdown from this architect into the file.

3

Profit

The Cursor AI will now prioritize these rules in Chat, Composer, and Inline edit modes.

.cursorrules Generator — Mastering the AI-Native IDE

The developer experience is shifting toward **AI-native programming**. Tools like **Cursor AI**, **Windsurf**, and **Cliner** have changed the workflow from "writing code" to "directing agents". However, an AI agent is only as good as the instructions it follows. Without a proper .cursorrules file, the AI may default to outdated patterns, ignore your project's specific linting rules, or use incompatible library versions.

The **Cursor AI Rules Architect** is the primary workbench for engineering high-fidelity system instructions for your IDE.

🧠 The Science of "Rules-Based Development"

A well-crafted .cursorrules file acts as the **source of truth** for the AI's "internal monologue." By defining these rules in your project root, you eliminate the need to repeat yourself in every chat session.

1. **Framework Enforcement**: Ensure the AI always uses Next.js App Router, React 19 hooks, or Tailwind v4 CSS variables without being prompted.

2. **Architectural Consistency**: Force the AI to follow your specific folder structure (e.g., "Always put business logic in /lib, not in /components").

3. **Security Guardrails**: Prevent the AI from suggesting insecure patterns or including sensitive environment variables in its generated code.

4. **Style Symmetry**: Ensure the AI's output matches your team's Prettier and ESLint configurations exactly.

⚡ Optimized for the "Composer" Era

Modern IDEs like Cursor rely on a feature called **Composer** to edit multiple files simultaneously. Our generator creates rules specifically weighted to improve the performance of multi-file edits, ensuring the AI maintains a coherent understanding of cross-file dependencies and imports.

🚀 How to Build your Ruleset

- **Select a Base**: Choose from industry-leading presets for Next.js, Python, or Rust.

- **Add Custom Logic**: Insert project-specific rules like "Use Lucide React for icons" or "Always write unit tests for utility functions."

- **Export & Deploy**: Copy the generated Markdown and save it to a .cursorrules file in your project root.

- **Verify**: Open Cursor and watch as the AI immediately acknowledges your new project standards.

🛡️ 100% Local — Zero Prompt Leakage

Your project's coding standards and architectural secrets remain local. Generating your .cursorrules through the DevUtility Hub is 100% client-side. We do not transmit your ruleset to any server, making this the safest way to architect your AI development environment.

Zero-Knowledge Execution & Edge Architecture

Unlike traditional monolithic developer utilities, DevUtility Hub operates entirely on a Zero-Knowledge architectural framework. When utilizing the Cursor AI Rules Architect (.cursorrules Generator), all computational workload is completely shifted to your local execution environment via WebAssembly (Wasm) and your browser's native JavaScript engine (such as V8 or SpiderMonkey).

Why Local Workloads Matter

Transmitting proprietary JSON objects, sensitive source code, or unencrypted text strings to an unknown third-party server introduces critical security vulnerabilities. By executing the Cursor AI Rules Architect (.cursorrules Generator) securely within the isolated sandbox of your Document Object Model (DOM), we structurally guarantee strict compliance with major data protection regulations like GDPR, CCPA, and HIPAA. We do not ingest, log, or telemetry your text payloads. Your local RAM serves as the absolute boundary.

Network-Free Performance

Furthermore, by completely eliminating asynchronous HTTP POST payloads to a centralized cloud infrastructure, we guarantee effectively zero latency. The Cursor AI Rules Architect (.cursorrules Generator) provides instant execution without arbitrary rate limits, artificial file size constraints, or server timeouts. Our global edge network serves the application wrapper, while your local machine handles the heavy lifting.
