Plexure API Search - Cursor Rules

Code Preservation Rules

Never remove existing code that is not directly related to the current change scope
Always maintain existing functionality unless explicitly requested to change
Keep all existing imports and dependencies unless they are specifically being refactored
Preserve existing error handling and logging mechanisms
Maintain existing configuration options and defaults
Keep all existing CLI commands and their functionality
Do not remove or modify existing tests unless they are directly related to changes
Preserve existing documentation unless it needs to be updated for new changes
