 ### Basic Usage
 
 ```{r,eval=FALSE}
-# Auto-configure all backends (default: half cores)
-setThreads()
-
 # Set explicit thread count
-setThreads(8)
+setThreads(8L)
 
 # Configure specific backends only
-setThreads(threads = 4, backend = "dt")      # data.table only
-setThreads(threads = 4, backend = "openmp")  # OpenMP only
+setThreads(threads = 4L, backend = "dt")      # data.table only
+setThreads(threads = 4L, backend = "openmp")  # OpenMP only
 ```
 
 ### TensorFlow Optimization
 ⚠️ **Must configure BEFORE importing TensorFlow**:
 
 ```{r,eval=FALSE}
 setThreads(
-  threads = 8,
+  threads = 8L,
   tf_config = list(
-    xla = TRUE,
-    inter_op = 2,
-    intra_op = 8
+    inter_op = 2L,
+    intra_op = 8L
   )
 )
 tf <- reticulate::import("tensorflow")  # Import AFTER configuration
