 ### Scheduler CLI:
 
-Run agents 24/7 with built-in safety features. Two modes available:
-
-**Direct Prompt Mode (Simple):**
 ```bash
-# No YAML needed - just provide your task
-praisonai schedule "Check AI news and summarize" --interval hourly
-
-# With options
-praisonai schedule "Monitor server logs" \
-  --interval "*/30m" \
-  --timeout 120 \

-  --verbose
+praisonai schedule start <name> "task" --interval hourly

+praisonai schedule describe <name>
+praisonai schedule save <name> [file.yaml]
+praisonai schedule "task" --interval hourly  # foreground mode
+praisonai schedule agents.yaml  # foreground mode
 ```
 
-**YAML Mode (Advanced):**
-```bash
-# Use agents.yaml for complex configurations
-praisonai schedule agents.yaml
-
-# With overrides
-praisonai schedule agents.yaml \
-  --interval "*/15m" \

-    instructions: "Search and summarize AI news"
-    tools:

-  run_immediately: true      # Run once on start
-  timeout: 60                # Max 60s per execution
-  max_cost: 1.00             # Stop after $1.00 spent
-```
-
-**Features:**
-- ⏱️ Timeout protection (prevent runaway executions)
-- 💰 Cost monitoring with budget limits
-- 📊 Real-time statistics (success rate, cost, runtime)
-- 🔄 Automatic retry with exponential backoff
-- 🛡️ Auto-stops when budget reached
