+**Changes**:
+- `--pages` parameter: Now optional, intelligently inferred from:
+  1. Explicit `--pages` if provided

+# Explicit override if needed
+/workflow:design:auto --prompt "SaaS app" --pages "dashboard,settings,billing"

 #### Usage Examples
 
 **Standalone Quick Prototyping**:
 ```bash
-# Pure text, agent exploration
-/workflow:design:auto --prompt "Modern minimalist blog, dark theme" --pages "home,article" --variants 3 --use-agent
+# Pure text with page inference (simplest)
+/workflow:design:auto --prompt "Modern minimalist blog with home, article and author pages, dark theme" --use-agent
 
-# Pure image, conventional mode
-/workflow:design:auto --images "refs/*.png" --pages "dashboard" --variants 2
+# Pure image with inferred pages
+/workflow:design:auto --images "refs/*.png" --variants 2
 
-# Hybrid input
-/workflow:design:auto --images "current-app.png" --prompt "Modernize with Linear.app style" --pages "tasks,settings" --use-agent
+# Hybrid input with explicit page override
+/workflow:design:auto --images "current-app.png" --prompt "Modernize to Linear.app style" --pages "tasks,settings" --use-agent

 **Integrated Workflow Enhancement**:
 ```bash
-# Within existing workflow session
