Reference All Affected Files
When a change spans multiple files, list every file that needs updating. Claude Code can only change what you point it to: if you forget to mention a dependency file, you'll end up with mismatched code.
Where you'll practice this
One Promptles scenario teaches this principle directly.
The Multi-File Update
You need to update your React navigation system. The `Header.tsx` component imports its color palette from `theme.ts` and its link definitions from `nav-links.ts`. You want to add a new "Dashboard" link with a teal accent color. This means changes in all three files.
Other principles in Context
Declare the Tools You Need
Name the tool or MCP server by name, and say what to do if it isn't reachable.
Describe Before You Prescribe
Describe the Data Shape
Claude can't clean data it can't picture.
Explain the Integration Point
Keep Memory Reusable
Save patterns and preferences that survive across sessions; never save snapshots of finished work.
Map to Real Components
Use Code Connect so it reuses your components, not new markup.
