Custom Instructions

Custom Instructions allow you to personalize how Kilo Code 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 Kilo's basic role definition. Examples include coding style, documentation standards, testing requirements, and workflow guidelines.

:::info Custom Instructions vs Rules 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. :::

    :::info Global Mode Rules
    If the mode itself is global (not workspace-specific), any custom instructions you set for it will also apply globally for that mode across all workspaces.
