Custom Instructions
Custom Instructions allow you to personalize how AI Cockpit Reasoning behaves, providing specific guidance that shapes responses, coding style, and decision-making processes.
What Are Custom Instructions?
Custom Instructions define specific Extension behaviors, preferences, and constraints beyond AI Cockpit's basic role definition. Examples include coding style, documentation standards, testing requirements, and workflow guidelines.
Custom Instructions are IDE-wide and are applied across all workspaces and maintain your preferences regardless of which project you're working on. Unlike Instructions, Custom Rules are project specific and allow you to setup workspace-based ruleset.
