+# HTTP Clients Rules
+
+1. All HTTP calls MUST be in clients/domains/
+2. Each domain MUST have its own client
+3. Clients MUST use the base HTTP client
+4. Clients MUST type their responses
+
+Example of correct client:
+
+```typescript
+import { HttpClient } from "@/clients/base/http-client";
+import { MyData } from "@/lib/types";
+
+export class MyClient {
+  constructor(private httpClient: HttpClient) {}
+
+  async getData(): Promise<MyData[]> {
+    return this.httpClient.get("/api/data");
+  }
+}
+```

+- Direct fetch calls
+- Business logic in clients
+- Untyped responses
