	Description		Read-only	Idempotent	Open world
`compare_ui_patterns`Explains how 2 to 4 easily confused UI patterns differ — e.g. toast vs snackbar, modal vs popover vs bottom sheet, tabs vs segmented control, Dynamic Island vs notch. Returns each definition side by side plus the catalog's written comparison when one exists. Accepts ids, names or short descriptions.

`get_implementation_prompt`Returns CatchUI's ready-to-use implementation instructions for 1 to 6 UI patterns — what to build, where it sits, its states and the accessibility it needs — in English or Chinese, for pasting into an AI coding tool such as Claude Code or Cursor. Accepts ids, names or short descriptions.

`get_ui_component_names`Returns what a UI pattern is called in code on each platform — SwiftUI, UIKit, Jetpack Compose, Android Views, Flutter, HTML/ARIA and, for system UI, AppKit, Win32 and Electron — or works backwards from a framework component (e.g. "UISegmentedControl", "ModalBottomSheet", "role=tablist") to the pattern and its equivalents elsewhere. Optionally filtered to one platform. Platforms without a native component say so instead of naming one.

`get_ui_pattern`Returns the full CatchUI entry for one UI pattern by id (e.g. "tabbar", "bottomsheet"): definition in English and Chinese, pronunciation, aliases, how people describe it, component names per platform, an implementation prompt, real search questions with answers, related patterns and the catalog URL. Takes an id; search_ui_patterns finds ids from descriptions.

`list_ui_patterns`Lists the 98 UI patterns in CatchUI's curated catalog — ids, English and Chinese names and one-line definitions — grouped by family, optionally filtered to one family (NAV, INPUT, ACTION, OVERLAY, FEEDBACK, CONTENT, DATA, SYSTEM).

`search_ui_patterns`Finds the conventional name of a UI element or design pattern from a plain-language description, question or term — e.g. "the bar at the bottom of an app", "three horizontal lines icon", "the black bar at the top of iPhone", "汉堡菜单". Searches CatchUI's curated catalog of 98 patterns and returns names in English and Chinese, definitions, the best-matching Q&A and each entry's catalog URL. Use when someone asks what a UI element is called or what a UI/UX term means.
