return await prompts.getPrompt({
promptName: "customer-support-prompt",
label: label,
});
},
});
```
### Available Labels
| Label | Purpose |
| ------------- | ----------------------- |
| `production` | Live production traffic |
| `staging` | Pre-production testing |
| `development` | Active development |
| `testing` | QA environments |
| `latest` | Most recent version |
You can also use custom labels (e.g., `beta`, `canary`, `region-eu`).
## Template Variables
Pass dynamic values to replace template variables in prompts:
```typescript
const agent = new Agent({
name: "DynamicAgent",
model: openai("gpt-4o-mini"),
instructions: async ({ prompts, context }) => {
return await prompts.getPrompt({
promptName: "customer-support-prompt",
label: "production",
variables: {
companyName: "VoltAgent Corp",
userName: context.get("userName") || "Guest",
tier: context.get("subscriptionTier") || "free",
},
});
},
});
```
### Using with Agent Context
```typescript
const userContext = new Map();
userContext.set("userName", "Alice");
userContext.set("subscriptionTier", "premium");
const response = await agent.generateText("I need help", {
context: userContext,
});
```
### Variable Sanitization
Sanitize user-provided variables to prevent prompt injection:
```typescript
instructions: async ({ prompts, context }) => {
const sanitizedUserName =
context.get("userName")?.replace(/[<>]/g, "")?.substring(0, 50) || "Guest";
return await prompts.getPrompt({
promptName: "personalized-greeting",
variables: { userName: sanitizedUserName },
});
};
```
## Caching
VoltOps supports two levels of caching to reduce API calls and improve performance.
### Global Cache
Configure caching at the VoltOpsClient level:
```typescript
const voltOpsClient = new VoltOpsClient({
publicKey: process.env.VOLTAGENT_PUBLIC_KEY,
secretKey: process.env.VOLTAGENT_SECRET_KEY,
prompts: true,
promptCache: {
enabled: true,
ttl: 300, // Seconds until expiration
maxSize: 100, // Maximum cached prompts
},
});
```
### Per-Prompt Cache Override
Override cache settings for individual fetches:
```typescript
// Disable cache for this specific fetch
return await prompts.getPrompt({
promptName: "customer-support-prompt",
promptCache: { enabled: false },
