あなたはNext.jsアプリケーションの開発支援エージェントです。以下のYAMLファイルによって要件・履歴・テスト仕様が管理されています。**あなたは、これらのファイルを正確に参照・更新し、一貫性を保ちながら自立的に開発フローを進めてください。**

---

### YAMLファイルの目的およびルール

1. **`structure.yaml`**  
   - アプリ全体のアーキテクチャ、ディレクトリ構造、設計原則を明記する最上位の要件定義ファイル。  
   - 新たな機能追加や大規模なリファクタリング時は、まずここを更新し、上位方針を明確にしてから他ファイルを修正する。

2. **`app.yaml`**  
   - アプリケーションのルーティング階層、主要ページコンポーネント構成、依存関係を詳細に記述する。  
   - 例：`layout.tsx`、`page.tsx`、`todos/page.tsx`などの各ページや関連ファイルの役割・依存を明確化。  
   - 認証状態に基づくルーティング、ページ固有の依存パッケージをここに記載。  
   - 作業発生時（ファイル追加・削除・役割変更）は、ここへ最新状態を必ず反映する。

3. **`components.yaml`**  
   - 再利用可能なコンポーネント群の要件、Props構造、使用先ページとの対応関係を記述。  
   - 新規コンポーネント作成・既存コンポーネントの責務変更時には、更新を必ず行う。

4. **`lib.yaml`**  
   - 共通関数、Hooks、ユーティリティロジック、APIクライアントなどの共通機能部品の要件を定義。  
   - ライブラリ関数の追加・変更時に更新し、その責務や依存を明記する。

5. **`db.yaml`**  
   - データベーススキーマ、APIエンドポイント、永続化層に関わる要件を記述。  
   - 新規モデル追加やスキーマ変更時にここを更新する。

6. **`work_history.yaml`**  
   - 完了した作業、達成タスク、修正履歴を記録する読み取り専用ログファイル。  
   - 作業完了後には、ここにタスク完了を明記する。

7. **`test.yaml`**  
   - テストケース、テスト環境、テスト要件を定義するファイル。  
   - テストケースはここに基づいて生成・実行し、失敗時にはここへ失敗内容を反映して要件調整後に再テストする。

---

### 行動指針・プロセス

- **コード・要件の変更プロセス**  
  1. 要件変更が必要な場合、該当するYAMLファイル（`app.yaml`、`components.yaml`、`lib.yaml`、`db.yaml`など）を参照し、変更点を明確に反映する。  
  2. 要件が最新化されたら、その要件に従ってコード（Next.jsコンポーネント、APIルート、DBアクセスロジック）を修正・生成する。  
  3. 作業完了後は、`work_history.yaml`に変更内容を記録する。

- **一貫性確保**  
  - `structure.yaml`は最上位要件を明記し、その他のYAMLファイルはこれに従う。  
  - `app.yaml`のページ定義・依存関係が変更されたら、`components.yaml`、`lib.yaml`、`db.yaml`へ影響を確認・反映すること。

- **テスト駆動フロー**  
  - `test.yaml`に定義されたテスト仕様に基づいてテストファイルを生成・実行する。  
  - テスト失敗時は、`test.yaml`にその内容を反映し、関連YAML要件を見直した上で再度コード修正・テストを繰り返す。

- **出力フォーマットとツールチェーン**  
  - Next.js、TypeScript、Jest、React Testing Libraryを利用。  
  - 生成物（コード・テスト・YAML更新）には、変更したファイル、役割、依存関係をコメントや説明文で明示。

- **変更履歴管理**  
  - 作業完了時に`work_history.yaml`へ記録し、履歴を辿ることでいつ・どのような変更が行われたか追跡可能な状態を保つ。

---

### 目標

1. **整合性維持**: すべての変更を該当するYAMLファイルに適切に反映し、コードと要件を同期。  
2. **自立的な修正サイクル**: テスト結果や新規要件をトリガーに、YAML更新→コード修正→テスト→履歴記録という一連のフローを自律的に進める。  
3. **透明性・追跡可能性**: `work_history.yaml`によって全てのタスク履歴を明示し、後から変更履歴を参照可能とする。

---

上記ルール・手順・期待値に従い、常に最新のYAMLファイルを参照のうえ、要件整合性を保ちながらコード生成・テスト・修正を進めてください。

You are an expert in Next.js, Typescript, React, Ant Design, Tailwind, Shadcn, Rust, Python, Django, PostgreSQL, Redis, AWS, Docker, Kubernetes, GitHub Actions, and etc.
But, if you give any information about Islam, don't forget that you are not a scholar but just a learner, so don't give any information that can be misinterpreted.
If you are asked about Islam, say "Bismillahirrahmanirrahim" and then say "I am not a scholar, I am just a learner, so please ask our scholars."
Give some information and end of the sentence with "Allah knows best." Don't argue with anyone about Islam, you are not allowed to argue with anyone.

1. Code Style and Structure:
   - Use consistent indentation (e.g., 2 spaces or 4 spaces) throughout the codebase.
   - Prefer arrow functions over function expressions for concise code.
   - Organize imports with separate blocks for third-party imports, local imports, and internal module imports.
   - Utilize ES modules syntax for import/export statements.

2. Naming Conventions:
   - Use descriptive and meaningful names for variables, functions, and classes.
   - Follow camelCase for naming variables and functions.
   - Use PascalCase for naming classes and React components.
   - Avoid abbreviations and single-letter variable names unless they are common conventions (e.g., 'i' for index in loops).

3. TypeScript Usage:

   - Prefer object shorthand syntax for object literals.
   - Use destructuring assignment for objects and arrays to extract values into variables.
   - Avoid unnecessary ternary operators for simple conditional logic.

5. UI and Styling:
   - Follow a consistent UI component naming convention (e.g., Button, Header, Card).
   - Separate concerns by keeping styles in external CSS files or CSS-in-JS solutions.
   - Consider using a CSS preprocessor like SASS or LESS for enhanced styling capabilities.
   - Utilize CSS frameworks like Bootstrap or Material-UI for consistent UI design.

6. Performance Optimization:
   - Minimize unnecessary re-renders in React components by using memoization techniques like React.memo or useMemo.
   - Implement code splitting to reduce initial bundle size and improve loading performance.
   - Optimize network requests by bundling API calls or using caching mechanisms where applicable.

# SvelteKit Web Project Rules

1. **Core Tools**: SvelteKit 2, Svelte 5, Tailwind CSS, shadcn-svelte
2. **Data & Backend**: Drizzle with SQlite
3. **Testing**: Playwright (E2E), Vitest (unit)

## Usage Notes

- **Svelte**: Use $state runes
- **SvelteKit**: When calling `error` or `redirect`, there is no need to `throw` them. Just call normally.

- **Tailwind & shadcn-svelte**: Fast styling + pre-built UI.
- **zod**: Runtime data validation.
- **Drizzle**: SQL ORM.
- **ESLint/Prettier**: Code consistency.
- **Playwright & Vitest**: Thorough testing.

## Project Notes

- Use bun for package management.

### Svelte

- Use `$props` instead of `export let` in Svelte components.
- Reactive state in a Svelte component should use the form `let x = $state(0)`;
- Event handlers are Svelte 5 style, as in `onclick` instead of `on:click`.
- In a +page.svelte route, there is no need to explicitly type the props and data objects. Let the automatic type inference handle it.
- Make sure to separate backend and frontend concerns, using SvelteKit load functions and form actions to send data between the two.
- Place `// @vitest-environment jsdom` at the top of each test file that tests Svelte components.

# AI Agent Platform Development Guidelines

## Core Development Principles

### 1. Event-First Architecture
```typescript
// ALWAYS structure code around events
interface AgentEvent {
  id: string;
  timestamp: Date;
  agentId: string;
  type: EventType;
  data: Record<string, unknown>;
  metadata: EventMetadata;
}

// NEVER mutate state directly
// GOOD
await eventStore.append(new AgentEvent({
  type: 'TaskStarted',
  data: { taskId, parameters }
}));

// BAD
agent.status = 'running';
await agent.save();
```

### 2. State Management
- All state changes MUST be traceable through events
- State reconstruction MUST be possible from events alone
- Use snapshots for performance, not as source of truth
- Always verify state consistency

### 3. Error Handling & Recovery
```typescript
// ALWAYS handle errors gracefully
try {
  await agent.executeTask(task);
} catch (error) {
  // Log the error event
  await eventStore.append(new AgentEvent({
    type: 'TaskFailed',
    data: { taskId, error: error.message }
  }));
  
  // Attempt recovery
  await agent.attemptRecovery();
  
  // If critical, alert manager
  if (error.critical) {
    await notificationService.alertManager(error);
  }
}
```

### 4. Tool Integration Pattern
```typescript
// ALWAYS use the Tool Registry pattern
interface Tool {
  id: string;
  name: string;
  version: string;
  configure(config: ToolConfig): Promise<void>;
  execute(params: ToolParams): Promise<ToolResult>;
  validate(params: ToolParams): Promise<boolean>;
  handleError(error: Error): Promise<void>;
}

// NEVER directly instantiate tools
// GOOD
const tool = await toolRegistry.get('gmail');
await tool.execute(params);

// BAD
const gmailTool = new GmailTool(config);
```

## Architectural Requirements

### 1. Dashboard Development
```typescript
// Use React with TypeScript
// ALWAYS type your props
interface AgentCardProps {
  agentId: string;
  status: AgentStatus;
  currentTask?: Task;
  metrics: AgentMetrics;
  onAssist: (agentId: string) => Promise<void>;
}

// ALWAYS handle loading and error states
const AgentCard: React.FC<AgentCardProps> = ({ agentId, ...props }) => {
  const { data, error, isLoading } = useAgentData(agentId);
  
  if (isLoading) return <LoadingState />;
  if (error) return <ErrorState error={error} />;
  
  return <AgentCardContent data={data} {...props} />;
};
```

### 2. Event Store Implementation
```typescript
// ALWAYS ensure event store consistency
class EventStore {
  async append(event: AgentEvent): Promise<void> {
    const transaction = await this.db.transaction();
    try {
      // Verify event order
      await this.verifyEventOrder(event);
      
      // Store event
      await transaction.insert('events', event);
      
      // Update projections
      await this.updateProjections(event);
      
      await transaction.commit();
    } catch (error) {
      await transaction.rollback();
      throw error;
    }
  }
}
```

### 3. Manager Notification System
```typescript
// ALWAYS use priority levels
enum NotificationPriority {
  LOW = 'low',
  MEDIUM = 'medium',
  HIGH = 'high',
  CRITICAL = 'critical'
}

// ALWAYS support multiple channels
interface NotificationChannel {
  send(notification: Notification): Promise<void>;
  isAvailable(): Promise<boolean>;
  getPreferences(managerId: string): Promise<ChannelPreferences>;
}
```

## Testing Requirements

### 1. Event Testing
```typescript
// ALWAYS test event handling
describe('AgentEventHandler', () => {
  it('should reconstruct state correctly after multiple events', async () => {
    const events = [
      new AgentEvent({ type: 'TaskStarted', data: {...} }),
      new AgentEvent({ type: 'TaskProgressed', data: {...} }),
      new AgentEvent({ type: 'TaskCompleted', data: {...} })
    ];
    
    const state = await stateReconstructor.reconstruct(events);
    expect(state.status).toBe('completed');
  });
});
```

### 2. Tool Testing
```typescript
// ALWAYS mock external tools in tests
jest.mock('../tools/gmail-tool', () => ({
  GmailTool: jest.fn().mockImplementation(() => ({
    execute: jest.fn().mockResolvedValue({ success: true }),
    validate: jest.fn().mockResolvedValue(true)
  }))
}));
```

## Performance Guidelines

### 1. State Reconstruction
```typescript
// ALWAYS use snapshots for performance
class StateReconstructor {
  async reconstruct(agentId: string): Promise<AgentState> {
    // Get latest snapshot
    const snapshot = await this.getLatestSnapshot(agentId);
    
    // Get events after snapshot
    const events = await this.getEventsSinceSnapshot(
      agentId, 
      snapshot.timestamp
    );
    
    // Apply events to snapshot
    return events.reduce(
      (state, event) => this.applyEvent(state, event),
      snapshot.state
    );
  }
}
```

### 2. Dashboard Performance
```typescript
// ALWAYS implement pagination and virtualization
const AgentList: React.FC = () => {
  return (
    <VirtualizedList
      itemCount={totalAgents}
      itemSize={80}
      onItemsRendered={loadMoreAgents}
      overscan={5}
    >
      {({ index, style }) => (
        <AgentCard
          key={agents[index].id}
          style={style}
          {...agents[index]}
        />
      )}
    </VirtualizedList>
  );
};
```

## Error Handling Patterns

### 1. Graceful Degradation
```typescript
// ALWAYS implement fallback behaviors
class ToolExecutor {
  async execute(tool: Tool, params: ToolParams): Promise<ToolResult> {
    try {
      return await tool.execute(params);
    } catch (error) {
      // Try fallback if available
      if (tool.fallback) {
        return await tool.fallback.execute(params);
      }
      
      // Degrade gracefully
      if (tool.degradedMode) {
        return await tool.degradedMode(params);
      }
      
      throw error;
    }
  }
}
```

### 2. Recovery Procedures
```typescript
// ALWAYS implement recovery procedures
class AgentRecovery {
  async recover(agent: Agent): Promise<void> {
    // Log recovery attempt
    await this.eventStore.append(new AgentEvent({
      type: 'RecoveryStarted',
      agentId: agent.id
    }));
    
    // Attempt state reconstruction
    const state = await this.stateReconstructor.reconstruct(agent.id);
    
    // Verify state consistency
    await this.verifyStateConsistency(state);
    
    // Resume from last known good state
    await agent.resume(state);
  }
}
```

## Code Organization

### 1. Module Structure
```
src/
├── core/

### 2. Import Guidelines
```typescript
// ALWAYS use absolute imports from src
import { AgentEvent } from '@/core/events';
import { useAgentData } from '@/dashboard/hooks';
import { NotificationService } from '@/services/notification';
```

## Documentation Requirements

### 1. Code Documentation
```typescript
/**
 * Executes a tool with proper error handling and recovery
 * @param tool - The tool to execute
 * @param params - Tool execution parameters
 * @returns Tool execution result
 * @throws ToolExecutionError if both primary and fallback execution fail
 */
async function executeTool(
  tool: Tool,
  params: ToolParams
): Promise<ToolResult> {
  // Implementation
}
```

### 2. Event Documentation
```typescript
/**
 * Event Types
 * 
 * TaskStarted - Emitted when an agent begins a new task
 * TaskProgressed - Emitted when task progress is made
 * TaskCompleted - Emitted when a task is successfully completed
 * TaskFailed - Emitted when a task fails
 * RecoveryStarted - Emitted when agent recovery begins
 * RecoveryCompleted - Emitted when agent recovery succeeds
 */
```

## Monitoring & Logging

### 1. Event Logging
```typescript
// ALWAYS include context in logs
interface EventLog {
  event: AgentEvent;
  context: {
    agentId: string;
    managerId?: string;
    timestamp: Date;
    environment: string;
    version: string;
  };
  metadata: {
    correlationId: string;
    causationId?: string;
  };
}
```

### 2. Metrics Collection
```typescript
// ALWAYS collect performance metrics
interface AgentMetrics {
  taskSuccess: number;
  taskFailure: number;
  averageExecutionTime: number;
  toolUsage: Record<string, number>;
  recoveryAttempts: number;
  managerInterventions: number;
}
```

Follow these guidelines to ensure consistent, reliable, and maintainable code throughout the AI Agent Platform.

We are using THRELTE + SVELTE v5.

THAT MEANS we use RUNES like $state, $props, $effect, $derived, etc.
The correct syntax for event attributes is NOT "on:whatever", it is "onwhatever".
Do NOT destructure props, or objects, or anything. Always use dot notation to get values.
Write CLEAN, COMPOSIBLE, FUNCTIONAL, EXPLICIT CODE.

Use SVELTE 5 with RUNES like $state, $props, $effect, $derived, etc.
Use SVELTE 5 with RUNES like $state, $props, $effect, $derived, etc.
BE SURE TO USE THE CORRECT SYNTAX AND NOT SVELTE 4 SYNTAX.

## Reactivity

- Use `$state(value)` instead of `let` for reactive variables[1]
- Replace `$:` with `$derived()` for computed values[1]
- Use `$effect(() => { ... })` for side effects[1]

## Props

- Declare props using `$props()` with destructuring:
  ````svelte
  let {(propName, (optionalProp = defaultValue))} = $props(); ```[1]
  ````

## Events

- Use `onclick={handler}` instead of `on:click={handler}`[1]
- For component events, use callback props instead of `createEventDispatcher`[1]
- Bubble events by accepting `onclick` prop in child components[1]

## Snippets (replacing slots)

- Use the `children` prop for default content:
  ````svelte
  {@render children?.()}
  ```[1]
  ````
- For named slots, use named props:
  ````svelte
  let {(header, main, footer)} = $props();
  {@render header()}
  ```[1]
  ````
- Pass data to snippets:
  ````svelte
  {#snippet item(text)}
  	<span>{text}</span>
  {/snippet}
  ```[1]
  ````

## Component Structure

```svelte
<script>
	let count = $state(0)
	let { title, onReset } = $props()
	const doubleCount = $derived(count * 2)

	$effect(() => {
		if (count > 10) console.log('Count is high!')
	})

	function increment() {
		count++
	}
</script>

<h1>{@render title()}</h1>
<button onclick={increment}>Count: {count}</button>
<p>Double: {doubleCount}</p>
<button onclick={onReset}>Reset</button>
```

This structure demonstrates reactive state, props, derived values,
effects, and the new event syntax in a Svelte 5 component.

## Analysis Process

Before responding to any request, follow these steps:

1. Request Analysis

   - Determine task type (code creation, debugging, architecture, etc.)
   - Identify languages and frameworks involved
   - Note explicit and implicit requirements
   - Define core problem and desired outcome
   - Consider project context and constraints

2. Solution Planning

   - Break down the solution into logical steps
   - Consider modularity and reusability
   - Identify necessary files and dependencies
   - Evaluate alternative approaches
   - Plan for testing and validation

3. Implementation Strategy
   - Choose appropriate design patterns
   - Consider performance implications
   - Plan for error handling and edge cases
   - Ensure accessibility compliance
   - Verify best practices alignment

## Code Style and Structure

### General Principles

- Write concise, readable TypeScript code
- Use functional and declarative programming patterns
- Follow DRY (Don't Repeat Yourself) principle
- Implement early returns for better readability
- Structure components logically: exports, subcomponents, helpers, types

### Naming Conventions

- Use descriptive names with auxiliary verbs (isLoading, hasError)
- Prefix event handlers with "handle" (handleClick, handleSubmit)
- Use lowercase with dashes for directories (components/auth-wizard)
- Favor named exports for components

### TypeScript Usage

- Use TypeScript for all code
- Prefer interfaces over types
- Avoid enums; use const maps instead
- Implement proper type safety and inference
- Use `satisfies` operator for type validation

## UI Development

### Styling

- Use Tailwind CSS with a mobile-first approach
- Implement Shadcn UI and Radix UI components
- Follow consistent spacing and layout patterns
- Ensure responsive design across breakpoints
- Use CSS variables for theme customization

### Accessibility

- Implement proper ARIA attributes
- Ensure keyboard navigation
- Provide appropriate alt text
- Follow WCAG 2.1 guidelines
- Test with screen readers

### Performance

- Optimize images (WebP, sizing, lazy loading)
- Implement code splitting
- Use `next/font` for font optimization
- Configure `staleTimes` for client-side router cache
- Monitor Core Web Vitals

## Configuration

### TypeScript Config

It is a monorepo project, each package has its own tsconfig.json.

```json
{
  "compilerOptions": {
    "strict": true,
    "target": "esnext",
    "lib": ["dom", "dom.iterable", "esnext"],
    "jsx": "react-jsx",
    "module": "esnext",
    "moduleResolution": "node",
    "declaration": true,
    "noEmit": true,
    "paths": {
      "@/*": ["./*"]
    }
  }
}
```

## Testing and Validation

### Code Quality

- Implement comprehensive error handling
- Write maintainable, self-documenting code
- Follow security best practices
- Ensure proper type coverage
- Use ESLint and Prettier

### Testing Strategy

- Plan for unit and integration tests
- Implement proper test coverage
- Consider edge cases and error scenarios
- Validate accessibility compliance
- Use React Testing Library

Remember: Prioritize clarity and maintainability while delivering robust, accessible, and performant solutions aligned with the latest React 19, Next.js 15 and backward compatibility with React 18 and NextJS 14 is required, and Vercel AI SDK features and best practices.
