Boost Your Cursor AI Workflow with Custom Modes and Minimal Prompts

Solution Approach

Cursor offers a powerful Custom Modes feature that extends the built‑in Agent, Ask, and Manual modes, allowing users to define dedicated workflows for specific development tasks. The main benefits include:

Workflow optimization : create task‑specific modes to dramatically improve efficiency.

Personalized AI behavior : fine‑tune AI responses with custom instructions.

Precise tool control : enable or disable specific tools as needed.

Model specificity : choose the most suitable model for each task.

Shortcut keys : assign hotkeys for one‑click mode activation.

Practical Steps

01. Enable Custom Modes

Using Cursor version v1.1.4, open Cursor Settings → Chat → Custom modes and turn on the feature. Open the chat window (shortcut Cmd/Ctrl + I), click “Add custom mode”, and fill in the basic properties:

Name

Icon

Shortcut key

Tool set

Default large model

Custom instructions (the reusable prompt template)

The following screenshot shows the configuration panel:

02. Define a Practical Custom Mode

As an example, the author adapts the UI‑prototype article to a new mode. After selecting the required tools, choose the model claude-4-sonnet (or claude-3.7-sonnet) and set the following custom instruction:

你是一名精通UI设计和产品规划的全栈工程师，专注于创建现代化、用户友好的应用原型。

你的核心任务是输出一套完整的应用原型图（HTML页面形式）来辅助后续的开发任务。

核心执行原则：
1. 功能与页面规划：基于用户需求构思并确定核心功能模块，规划HTML页面清单，确保页面间逻辑清晰。
2. 产品与UI/UX设计：以产品经理视角规划关键功能、页面流程和交互逻辑；以设计师视角输出符合现代设计趋势的美观UI/UX。
3. 技术规范：使用HTML5、Font Awesome、Tailwind CSS和必要的JavaScript；图片素材使用Unsplash或占位图；代码简洁、可读、可维护；响应式设计，适配不同屏幕尺寸。
4. 输出要求：创建包含多个HTML页面的完整原型，主页面命名为index.html，可链接其他页面；功能页面使用英文名称（如courses.html、profile.html）；采用现代移动或Web应用的设计风格；index.html展示主要功能入口或预览；所有文本使用简体中文。
5. 设计标准：遵循顶级UX审美，注重用户体验和交互流畅性，使用一致的设计语言和视觉元素，确保可访问性和易用性。

请直接开始设计并输出符合上述要求的HTML原型页面代码，从index.html开始，然后是其他核心功能页面。每个页面都应该是完整可运行的HTML文件。

The tool list that can be enabled for a custom mode includes:

Search tools : Read File, List Directory, Codebase, Grep, Search Files, Web

Editing tools : Edit & Reapply, Delete File

Running tools : Terminal

Advanced tools : Auto‑apply Edits, Auto‑run, Auto‑fix Errors

MCP tools : extend third‑party integration capabilities

03. Result Demonstration

With the custom mode defined, a concise natural‑language prompt can generate the full UI prototype in seconds. The author notes that claude‑4‑sonnet produces richer colors compared to claude‑3.7‑sonnet. A side‑by‑side comparison image is shown below:

The same approach can be extended to generate PRD documents, task breakdowns, debugging workflows, and more.

Summary

Using Custom Modes lets you focus on core requirements while avoiding repetitive role‑setting and workflow descriptions, dramatically improving development efficiency and turning the AI into a true intelligent partner. Currently, Cursor supports up to five custom modes simultaneously.
