Filtrage du contenu

Imposer des limites de longueur aux prompts

Ajouter des préférences utilisateur

interface UserPreferences {

Limitation de débit de données

const promptTimestamps: number[] = [];
const RATE_LIMIT = 10; // prompts

  hooks: {
    onUserPromptSubmitted: async (input) => {
      const now = Date.now();
      
      // Remove timestamps outside the window

Modèles d’invite

const TEMPLATES: Record<string, (args: string) => string> = {

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({

        if (input.prompt.toLowerCase().startsWith(prefix)) {
          const args = input.prompt.slice(prefix.length).trim();
          return {

Bonnes pratiques

1. Conserver l’intention de l’utilisateur : lors de la modification des invites, vérifiez que l’intention principale reste claire.

2. Soyez transparent sur les modifications : si vous modifiez considérablement une invite, envisagez de journaliser ou de notifier l’utilisateur.

3. Utilisez additionalContext plutôt que modifiedPrompt - Ajouter du contexte est moins intrusif que de réécrire l’invite.

4. Fournissez des motifs de rejet clairs - Lorsque vous rejetez des prompts, expliquez pourquoi et comment les corriger.

5. Maintenez un traitement rapide - Ce hook s’exécute à chaque message utilisateur. Évitez les opérations lentes.
