### Agregar contexto del proyecto

```typescript
const session = await client.createSession({
  hooks: {
    onUserPromptSubmitted: async (input) => {
      const projectInfo = await getProjectInfo();
      
      return {
        additionalContext: `
Project: ${projectInfo.name}
Language: ${projectInfo.language}
Framework: ${projectInfo.framework}
        `.trim(),
      };
    },
  },
});
```

### Expandir comandos abreviados

```typescript
const SHORTCUTS: Record<string, string> = {
  "/fix": "Please fix the errors in the code",
  "/explain": "Please explain this code in detail",

  hooks: {
    onUserPromptSubmitted: async (input) => {
      for (const [shortcut, expansion] of Object.entries(SHORTCUTS)) {
        if (input.prompt.startsWith(shortcut)) {
          const rest = input.prompt.slice(shortcut.length).trim();
          return {
            modifiedPrompt: `${expansion}${rest ? `: ${rest}` : ""}`,
          };
        }
      }
      return null;
    },
  },
});
```

### Filtrado de contenido

```typescript
const BLOCKED_PATTERNS = [
  /password\s*[:=]/i,
  /api[_-]?key\s*[:=]/i,
  /secret\s*[:=]/i,
];

const session = await client.createSession({
  hooks: {
    onUserPromptSubmitted: async (input) => {
      for (const pattern of BLOCKED_PATTERNS) {
        if (pattern.test(input.prompt)) {
          // Replace the prompt with a warning message
          return {
            modifiedPrompt: "[Content blocked: Please don't include sensitive credentials in your prompts. Use environment variables instead.]",
            suppressOutput: true,
          };
        }
      }
      return null;
    },
  },
});
```

### Aplicar límites de longitud a los prompts

```typescript
const MAX_PROMPT_LENGTH = 10000;

const session = await client.createSession({
  hooks: {
    onUserPromptSubmitted: async (input) => {
      if (input.prompt.length > MAX_PROMPT_LENGTH) {
        // Truncate the prompt and add context
        return {
          modifiedPrompt: input.prompt.substring(0, MAX_PROMPT_LENGTH),
          additionalContext: `Note: The original prompt was ${input.prompt.length} characters and was truncated to ${MAX_PROMPT_LENGTH} characters.`,
        };
      }
      return null;
    },
  },
});
```

### Agregar preferencias de usuario

```typescript
interface UserPreferences {
  codeStyle: "concise" | "verbose";
  preferredLanguage: string;
  experienceLevel: "beginner" | "intermediate" | "expert";
}

const session = await client.createSession({
  hooks: {
    onUserPromptSubmitted: async (input) => {
      const prefs: UserPreferences = await loadUserPreferences();
      
      const contextParts = [];
      
      if (prefs.codeStyle === "concise") {
        contextParts.push("User prefers concise code with minimal comments.");
      } else {
        contextParts.push("User prefers verbose code with detailed comments.");
      }
      
      if (prefs.experienceLevel === "beginner") {
        contextParts.push("Explain concepts in simple terms.");
      }
      
      return {
        additionalContext: contextParts.join(" "),
      };
    },
  },
});
```

### Avisos de umbral de uso

```typescript
const promptTimestamps: number[] = [];
const NOTICE_THRESHOLD = 10; // prompts
const RATE_WINDOW = 60000; // 1 minute

const session = await client.createSession({
  hooks: {
    onUserPromptSubmitted: async (input) => {
      const now = Date.now();
      
      // Remove timestamps outside the window
      while (promptTimestamps.length > 0 && promptTimestamps[0] < now - RATE_WINDOW) {
        promptTimestamps.shift();
      }

      promptTimestamps.push(now);
      if (promptTimestamps.length >= NOTICE_THRESHOLD) {
        // This is advisory context for the model, not an enforced rate limit.
        // Enforce hard limits before calling session.send().
        return {
          additionalContext: `The user has sent ${promptTimestamps.length} prompts in the last minute. Suggest waiting before sending more.`,
        };
      }

      return null;
    },
  },
});
```

### Plantillas de solicitud

```typescript
const TEMPLATES: Record<string, (args: string) => string> = {
  "bug:": (desc) => `I found a bug: ${desc}

Please help me:
1. Understand why this is happening
2. Suggest a fix
3. Explain how to prevent similar bugs`,

  "feature:": (desc) => `I want to implement this feature: ${desc}

Please:
1. Outline the implementation approach
2. Identify potential challenges
3. Provide sample code`,
};

const session = await client.createSession({
  hooks: {
    onUserPromptSubmitted: async (input) => {
      for (const [prefix, template] of Object.entries(TEMPLATES)) {
        if (input.prompt.toLowerCase().startsWith(prefix)) {
          const args = input.prompt.slice(prefix.length).trim();
          return {
            modifiedPrompt: template(args),
          };
        }
      }
      return null;
    },
  },
});
```

## procedimientos recomendados

1. **Conservar la intención del usuario** : al modificar las solicitudes, asegúrese de que la intención principal permanece clara.

2. **Ser transparente acerca de las modificaciones** : si cambia significativamente un mensaje, considere la posibilidad de registrar o notificar al usuario.

3. **Usa `additionalContext` en lugar de `modifiedPrompt`** - Añadir contexto es menos intrusivo que reescribir la instrucción.

4. **Use `additionalContext` para obtener instrucciones de asesoramiento**: este enlace no puede rechazar una solicitud ni aplicar una directiva. Aplicar límites estrictos antes de llamar a `session.send()`.

5. **Mantén el procesamiento rápido** - Este hook se ejecuta con cada mensaje del usuario. Evite las operaciones lentas.
