Project-based JSON Settings for Cursor

Project-Based Settings in Cursor AI IDE :dart:

Introduction

Cursor AI is already an immensely powerful and intuitive IDE that empowers developers with AI-assisted coding, seamless workflows, and unparalleled efficiency. However, as developers, we thrive on precision, customization, and adaptability. One major limitation in the current Cursor experience is the lack of project-specific settings, forcing us to rely solely on global configurations. This restricts flexibility, leads to unnecessary context switching, and ultimately hinders the IDE’s true potential.

:star2: Why This Matters

In modern development environments, every project has unique requirements:

  • Language Preferences: Some projects demand strict TypeScript rules, others need loose JavaScript configurations.
  • AI Interaction Models: Different projects require different AI guidance styles—some need verbose explanations, while others require succinct responses.
  • Extensions & Tools: What works for a Python-based ML project may be redundant for a React front-end.
  • Performance & Resource Allocation: Projects with heavy dependencies and large codebases might require different memory configurations.
  • Linting & Formatting Rules: A Next.js project follows a different ESLint and Prettier setup than a Golang microservices project.

:construction: The Current Pain Points

Without project-based settings, developers must manually switch configurations when moving between different codebases. This results in:

  • Context Loss: Cursor AI’s responses may be optimized for the wrong project, leading to incorrect or inefficient suggestions.
  • Workflow Disruptions: Constant toggling between settings wastes time and cognitive energy.
  • Inconsistent Project Standards: Teams using Cursor must manually enforce and remember settings across multiple projects.
  • Reduced Personalization: AI should adapt per project, not force users into a one-size-fits-all approach.

:fire: The Proposed Solution: Project-Based Settings

We propose adding a Project Settings layer in Cursor AI that allows developers to define configurations per project. This could include:

:white_check_mark: Project-Specific AI Preferences

  • AI verbosity level (detailed vs. concise responses)
  • AI assistant tone (formal, friendly, technical, exploratory)
  • Specific coding styles and best practices per project

:white_check_mark: Custom Development Environments

  • Linting, formatting, and syntax highlighting per project
  • Preferred extensions and tools automatically loaded
  • Memory and performance settings for large-scale projects

:white_check_mark: Intelligent Context Switching

  • Cursor automatically detects and applies the correct settings when switching projects
  • AI maintains relevant context per project without confusion

:white_check_mark: Configurable Through UI & JSON

  • A dedicated “Project Settings” UI under Cursor’s settings menu
  • Alternatively, settings could be defined in a .cursor.json or .cursor-settings.yaml file within the project directory.
  • This JSON file is the source-of-truth for the project settings, but it can also be edited from the UI. This will make it up to the developer to engineer their JSON file and start from a simple basic template.

:bulb: Example Implementation

A simple .cursor.json configuration could look like this:

{
  "aiVerbosity": "concise",
  "linting": "eslint",
  "formatting": "prettier",
  "extensions": ["tailwindcss", "graphql"],
  "performance": {
    "memory": "high",
    "optimizeForLargeFiles": true
  }
}

When Cursor detects this file in a project’s root directory, it automatically applies the settings, ensuring a seamless and optimized development experience.

:earth_africa: The Bigger Picture

Cursor AI is already revolutionizing how we code. Adding project-based settings would take it to the next level, making it the ultimate adaptive, context-aware, and developer-friendly IDE. With this feature, Cursor will not only be an assistant—it will be a true coding partner that understands each project’s needs and adapts accordingly.

Let’s unlock Cursor’s full potential and take AI-powered development to the next stage. Who’s with me? :rocket::fire:

With the latest update in Cursor, you now have access to project-specific rules. This is even more granular than the .cursorrules file, which was already specific to the project you were working in.

Now you can create custom rules for:

  1. Different directories
  2. File types
  3. Semantic descriptions

Take a look through the documentation here, as I think this might help address many of your current pain points.

Hi Jake!

Yes, thank you! I realized that last night :grin:
It’s awesome! I’ll test it in the coming days and let you know my findings…

Cheers :metal:
