AGENTS.md & Multi-Agent Rules Studio (Cursor, Claude, Copilot, Windsurf)

Universal AI coding agent rules generator. Creates RFC-compliant AGENTS.md files with stack-aware build commands, testing protocols, code conventions, and 1-click export to .cursorrules, CLAUDE.md, and Copilot instructions.

Stack-aware preset templates (Next.js 15, Astro 5, React 19, FastAPI, Go, Rust, Flutter)
Setup & build command manager (install, dev, build, test, lint, typecheck)
Anti-hallucination & safety toggles (Verification before completion, preserve comments, strict typing)
Simultaneous multi-vendor export: AGENTS.md, .cursorrules, CLAUDE.md, and Copilot instructions
Automatic cross-referencing for DESIGN.md visual token synchronization
Directory tree & architectural boundary mapping
WebCraftKit Manifesto 100% Client-Side Engine

How to Write Production-Grade AGENTS.md Files for AI Coding Agents

In-depth specifications, architectural mechanics, real-world code implementations, and industry best practices.

01

What is AGENTS.md and Why is it the Open Universal Standard?

Historically, every AI tool introduced its own proprietary rule format: Cursor used `.cursorrules`, Claude Code introduced `CLAUDE.md`, GitHub Copilot uses `.github/copilot-instructions.md`, and Windsurf uses `.windsurfrules`.

`AGENTS.md` (standardized at agents.md) is the open, universal markdown specification supported across OpenAI Codex, Cursor, Sourcegraph Amp, Aider, Jules, RooCode, and Claude. Placing an `AGENTS.md` in your repo root gives all current and future AI agents a single source of truth.

02

Essential Sections in a High-Performing AGENTS.md

A high-performing agent file must contain six core sections: 1. Project Overview & Runtime Environment (Node.js, Python, Go version, package manager) 2. Deterministic Command Map (Exact terminal commands for dev, build, test, lint) 3. Architectural Principles & Folder Map (Layered UI vs Logic vs Data separation) 4. Code Conventions (TypeScript strictness, component export conventions, state management) 5. Anti-Hallucination Guardrails (Never assert passing tests without running verification) 6. Visual & UI Alignment (Cross-referencing `DESIGN.md`)

Implementation Example
# AGENTS.md — Repository Guidance for AI Coding Agents

## 1. Environment & Setup
- Runtime: Node.js 22.x LTS (pnpm)
- Framework: Astro 5.4 + React 19 + Tailwind CSS v4
- Commands:
  - Dev Server: `pnpm dev` (port 4321)
  - Typecheck: `npx tsc --noEmit`
  - Production Build: `pnpm build`

## 2. Core Architectural Rules
- 100% Client-Side Computation: Never introduce backend API routes for data processing.
- Strict Verification: Always execute typechecks and test builds before declaring completion.
- Comment Preservation: Preserve existing docstrings and explanatory code comments.

## 3. Design System Alignment
- Follow all color tokens, typography scales, and component structures defined in `DESIGN.md`.
03

Generating Vendor-Specific Files (.cursorrules, CLAUDE.md, Copilot)

While `AGENTS.md` is the universal standard, our studio allows you to generate and export exact vendor-specific files (.cursorrules, CLAUDE.md, .github/copilot-instructions.md) with 1-click tab switching or bulk ZIP packaging.

04

Best Practices for Monorepos and Subdirectory Agents

In monorepos (Turborepo, Nx, pnpm workspaces), place an `AGENTS.md` at the repository root for global rules, and lightweight localized `AGENTS.md` files inside `/apps/web` or `/packages/api`. AI agents walk up the directory tree and inherit the closest rule file.
