+# Prompt 03: Add Search
+
+Copy and paste this into Claude Code:
+
+---
+
+Add a search bar to the todo app. Requirements:
+
+- Search input at the top, above the category filter buttons
+- Filters tasks in real time as the user types (no search button needed)
+- Searches both the task text and the category name
+- Works together with the category filters (search within the active category)
+- Subtle search icon or placeholder text "Search tasks..."
+- Clear button (x) to reset the search
+- If no tasks match, show a "No tasks found" message
+- Keep the existing design
+
+---
+
+## What to Expect
+
+- A search field appears at the top of the app
+- Typing immediately filters the visible tasks
+- Search combines with category filters (search "meeting" in "Work" category)
+- Clearing the search shows all tasks in the current filter again
