# Garnish — Craft CMS Control Panel JavaScript Toolkit Reference for Garnish, Craft CMS's built-in JavaScript UI framework. Covers the class system, UI widgets, drag interactions, form components, accessibility helpers, and integration with Craft's CP. This skill is scoped to **Garnish itself** — the JavaScript library at `src/web/assets/garnish/`. For PHP-side plugin development (elements, controllers, services), see the `craftcms` skill. For CP template markup that Garnish widgets attach to, see the `craftcms` skill's `cp.md` reference. ## Companion Skills — Load When Needed - **`craftcms`** — Load when the task involves PHP asset bundle classes, plugin architecture, or CP template markup that Garnish widgets attach to. Skip for pure JavaScript refactoring, Garnish API questions, or JS-only tasks. - **`craft-php-guidelines`** — Load only when editing PHP files (asset bundle classes, controllers that register JS). Skip for pure JS work. ## Documentation - Garnish source: `src/web/assets/garnish/src/` in the Craft CMS repository - No official external documentation exists — this skill IS the documentation. Use `WebFetch` on Craft's class reference (https://docs.craftcms.com/api/v5/) when looking up PHP-side asset bundle registration. ## Common Pitfalls (Cross-Cutting) - Using jQuery `.on()` directly instead of `this.addListener()` — listeners added via jQuery won't auto-clean on `destroy()`, causing memory leaks. - Forgetting `this.base()` when overriding `destroy()`...
