## Context Builder

## Token Manager

### Token Counter

```typescript
// src/modules/copilot/context/token-counter.ts

import { encoding_for_model, TiktokenModel } from 'tiktoken';

@Injectable()
export class TokenCounter {

### Context Compressor

```typescript

### Conversation Summarizer

```typescript
// src/modules/copilot/context/summarizer.ts

@Injectable()
export class ConversationSummarizer {
  constructor(private readonly llmProvider: LLMProviderService) {}

  async summarize(messages: Message[]): Promise<string> {
    if (messages.length === 0) return '';

    const formattedMessages = messages.map(m =>
      `${m.role}: ${m.content}`
    ).join('\n');

    const response = await this.llmProvider.createChatCompletion({
      model: 'gpt-4o-mini', // Use smaller model for summarization
      messages: [
        {
          role: 'system',
          content: `Eres un asistente que resume conversaciones de trading.
Crea un resumen conciso (máximo 100 palabras) que capture:
- Símbolos mencionados
- Análisis o estrategias discutidas
- Decisiones o conclusiones importantes
- Preguntas pendientes del usuario

Formato: Lista de puntos clave.`,
        },
        {
          role: 'user',
          content: `Resume esta conversación:\n\n${formattedMessages}`,
        },
      ],
      max_tokens: 200,
    });

    return response.choices[0].message.content;
  }
}
```

## Memory Store
