Add CLAUDE.md - AI agent instructions for module development

Created comprehensive anti-hallucination documentation:
- EXACT file templates with full code examples
- Precise naming conventions (PascalCase, snake_case, kebab-case)
- Step-by-step module creation checklist
- Common mistakes to avoid section
- Filament form/table component reference
- Debugging commands and troubleshooting
- Updated AI_CONTEXT.md and README.md to reference CLAUDE.md

+# AI Agent Instructions for Laravel Module Development
+
+> **CRITICAL**: This document provides EXACT specifications for building modules in this Laravel template.
+> Follow these instructions PRECISELY. Do NOT deviate, guess, or improvise.
+> When in doubt, READ THE EXISTING CODE before making changes.
+
+---
+
+## 🚨 BEFORE YOU START - MANDATORY STEPS
+
+### 1. Always Check Existing Patterns First
+```bash
+# List existing modules to see patterns
+ls -la src/app/Modules/
+
+# Read an existing module's structure
+find src/app/Modules/[ExistingModule]/ -type f -name "*.php"
+```
+
+### 2. Always Check Logs After Errors
+```bash
+docker-compose exec app tail -n 100 storage/logs/laravel.log
+```
+
+### 3. Never Guess at Solutions
+- If you encounter an error, READ the full stack trace
+- Find the EXACT file and line number causing the issue
+- Understand what the code is trying to do before fixing

+## 📝 EXACT FILE TEMPLATES
+
+### 1. Service Provider (REQUIRED)
+
+**File**: `src/app/Modules/[ModuleName]/[ModuleName]ServiceProvider.php`
+
+```php
+<?php
+
+namespace App\Modules\[ModuleName];
+
+use Illuminate\Support\ServiceProvider;
+use Illuminate\Support\Facades\Route;
+
+class [ModuleName]ServiceProvider extends ServiceProvider
+{
+    public function register(): void

+
+**NAMING RULES**:

+
+namespace App\Modules\[ModuleName]\Filament\Resources\[ModelName]Resource\Pages;

+    {
+        return [
+            Actions\DeleteAction::make(),
+        ];
+    }
+}
+```
+
+### 8. Routes (REQUIRED)
+
+**File**: `src/app/Modules/[ModuleName]/Routes/web.php`
+```php
+<?php
+
+use App\Modules\[ModuleName]\Http\Controllers\[ModuleName]Controller;
+use Illuminate\Support\Facades\Route;
+
+Route::get('/', [[ModuleName]Controller::class, 'index'])->name('index');
+```
+
+**File**: `src/app/Modules/[ModuleName]/Routes/api.php` (if API needed)
+```php
+<?php
+
+use Illuminate\Support\Facades\Route;
+
+Route::middleware('auth:sanctum')->group(function () {
+    // API routes here
+});
+```
+
+### 9. Controller (REQUIRED)
+
+**File**: `src/app/Modules/[ModuleName]/Http/Controllers/[ModuleName]Controller.php`
+```php
+<?php
+
+namespace App\Modules\[ModuleName]\Http\Controllers;
+
+use App\Http\Controllers\Controller;
+use Illuminate\Http\Request;
+
+class [ModuleName]Controller extends Controller
+{
+    public function index()
+    {
+        $this->authorize('[module_name].view');
+        
+        return view('[module-slug]::index');
+    }
+}
+```
+
+### 10. Index View (REQUIRED)
+
+**File**: `src/app/Modules/[ModuleName]/Resources/views/index.blade.php`
+```blade
+<x-app-layout>
+    <x-slot name="header">
+        <h2 class="font-semibold text-xl text-gray-800 dark:text-gray-200 leading-tight">
+            {{ __('[Module Display Name]') }}
+        </h2>
+    </x-slot>
+
+    <div class="py-12">
+        <div class="max-w-7xl mx-auto sm:px-6 lg:px-8">
+            <div class="bg-white dark:bg-gray-800 overflow-hidden shadow-sm sm:rounded-lg">
+                <div class="p-6 text-gray-900 dark:text-gray-100">
+                    {{ __('[Module Display Name] content goes here.') }}
+                </div>
+            </div>
+        </div>
+    </div>
+</x-app-layout>
+```
+
+---
+
+## ✅ MODULE REGISTRATION
+
+After creating all files, register the module in `src/config/app.php` providers array:
+
+```php
+'providers' => ServiceProvider::defaultProviders()->merge([
+    // ...existing providers...
+    App\Modules\[ModuleName]\[ModuleName]ServiceProvider::class,
+])->toArray(),
+```
+
+Or add to `src/bootstrap/providers.php`:
+```php
+return [
+    App\Providers\AppServiceProvider::class,
+    // ...existing providers...
+    App\Modules\[ModuleName]\[ModuleName]ServiceProvider::class,
+];
+```
+
+---
+
+## 🔄 AFTER MODULE CREATION - REQUIRED COMMANDS
+
+```bash
+# 1. Run migrations
+docker-compose exec app php artisan migrate
+
+# 2. Clear all caches
+docker-compose exec app php artisan optimize:clear
+
+# 3. Seed permissions (if using permissions)
+docker-compose exec app php artisan db:seed --class=RolePermissionSeeder
+
+# 4. Reset permission cache
+docker-compose exec app php artisan permission:cache-reset
+```
+
+---
+
+## ⚠️ COMMON MISTAKES TO AVOID
+
+### 1. Wrong Namespace
+❌ `namespace App\Modules\StockManagement\Models;`
+✅ `namespace App\Modules\StockManagement\Models;`
+
+The namespace MUST match the folder structure EXACTLY.
+
+### 2. Wrong View Namespace
+❌ `return view('stockmanagement::index');`
+❌ `return view('StockManagement::index');`
+✅ `return view('stock-management::index');`
+
+View namespace is ALWAYS kebab-case.
+
+### 3. Wrong Permission Names
+❌ `'StockManagement.view'`
+❌ `'stock-management.view'`
+✅ `'stock_management.view'`
+
+Permissions are ALWAYS snake_case.
+
+### 4. Forgetting to Register Provider
+The module WILL NOT LOAD if you forget to add its ServiceProvider.
+
+### 5. Wrong Import Paths
+❌ `use App\Models\Product;`
+✅ `use App\Modules\StockManagement\Models\Product;`
+
+Module models are in the MODULE namespace, not the core App namespace.
+
+### 6. Missing Fillable Array
+❌ Empty `$fillable` array causes mass-assignment errors
+✅ List ALL fields that should be mass-assignable
+
+### 7. Forgetting to Run Migrations
+Always run `php artisan migrate` after creating migrations.

+## 📊 FILAMENT TABLE COLUMN REFERENCE
+
+```php

+    ->searchable()
+    ->sortable();
+
+// Badge
+Tables\Columns\TextColumn::make('status')

+        'active' => 'success',
+        'inactive' => 'danger',

+
+## 🔐 EXISTING CORE RESOURCES
+
+### User Management (already exists in template)
+- `src/app/Filament/Resources/UserResource.php` - User CRUD with role assignment
+- `src/app/Filament/Resources/RoleResource.php` - Role CRUD with permissions
+- `src/app/Filament/Resources/PermissionResource.php` - Permission CRUD
+
+### Settings (already exists)
+- `src/app/Filament/Pages/Settings.php` - Site settings (name, logo, colors, registration toggle)
+- `src/app/Models/Setting.php` - Settings model with get/set helpers
+
+### Authentication (pre-installed)
+- Laravel Breeze with Blade templates
+- Login: `/login`
+- Register: `/register` (controlled by enable_registration setting)
+- Admin: `/admin`

+## 📋 CHECKLIST FOR NEW MODULES
+
+Before considering a module complete:
+
+- [ ] ServiceProvider created and registered
+- [ ] Config file created
+- [ ] Model created with fillable and casts
+- [ ] Migration created and run
+- [ ] Permissions.php created
+- [ ] Filament Resource created with all pages
+- [ ] Controller created
+- [ ] Routes (web.php and optionally api.php) created
+- [ ] Index view created
+- [ ] `php artisan migrate` run
+- [ ] `php artisan optimize:clear` run
+- [ ] `php artisan db:seed --class=RolePermissionSeeder` run
+- [ ] Module accessible at `/[module-slug]`
+- [ ] Admin panel shows module in navigation
+- [ ] CRUD operations work in admin

+
+## 🆘 DEBUGGING
+
+### Module Not Loading
+```bash
+# Check if provider is registered
+docker-compose exec app php artisan about
+
+# Clear everything
+docker-compose exec app php artisan optimize:clear
+```
+
+### Filament Resource Not Showing
+```bash
+# Clear Filament cache
+docker-compose exec app php artisan filament:cache-components
+
+# Check canAccess() method returns true
+# Check user has required permission
+```
+
+### Permission Denied
+```bash
+# Reset permission cache
+docker-compose exec app php artisan permission:cache-reset
+
+# Verify permissions exist
+docker-compose exec app php artisan tinker
+>>> \Spatie\Permission\Models\Permission::pluck('name');
+```
+
+### View Not Found
+```bash
+# Verify view namespace (must be kebab-case)
+# Check file exists in Resources/views/
+```
+

+
+**Remember**: When in doubt, look at existing code in the codebase. The patterns are already established - follow them exactly.
