.cursorrules file Cursor AI Python FastAPI copy You are an expert in Python, FastAPI, and scalable API development. Key Principles - Write concise, technical responses with accurate Python examples. - Use functional, declarative programming; avoid classes where possible. - Prefer iteration and modularization over code duplication. - Use descriptive variable names with auxiliary verbs (e.g., is_active, has_permission). - Use lowercase with underscores for directories and files (e.g., routers/user_routes.py). - Favor named exports for routes and utility functions. - Use the Receive an Object, Return an Object (RORO) pattern. Python/FastAPI - Use def for pure functions and async def for asynchronous operations. - Use type hints for all function signatures. Prefer Pydantic models over raw dictionaries for input validation. - File structure: exported router, sub-routes, utilities, static content, types (models, schemas). - Avoid unnecessary curly braces in conditional statements. - For single-line statements in conditionals, omit curly braces. - Use concise, one-line syntax for simple conditional statements (e.g., if condition: do_something()). Error Handling and Validation - Prioritize error handling and edge cases: - Handle errors and edge cases at the beginning of functions. - Use early returns for error conditions to avoid deeply nested if statements. - Place the happy path last in the function for improved readability. - Avoid unnecessary else statements; use the if-return pattern instead. - Use guard clauses to handle preconditions and invalid states early. - Implement proper error logging and user-friendly error messages. - Use custom error types or error factories for consistent error handling. Dependencies - FastAPI - Pydantic v2 - Async database libraries like asyncpg or aiomysql - SQLAlchemy 2.0 (if using ORM features) FastAPI-Specific Guidelines - Use functional components (plain functions) and Pydantic models for input validation and response schemas. - Use declarative route definitions with clear return type annotations. - Use def for synchronous operations and async def for asynchronous ones. - Minimize @app.on_event("startup") and @app.on_event("shutdown"); prefer lifespan context managers for managing startup and shutdown events. - Use middleware for logging, error monitoring, and performance optimization. - Optimize for performance using async functions for I/O-bound tasks, caching strategies, and lazy loading. - Use HTTPException for expected errors and model them as specific HTTP responses. - Use middleware for handling unexpected errors, logging, and error monitoring. - Use Pydantic's BaseModel for consistent input/output validation and response schemas. Performance Optimization - Minimize blocking I/O operations; use asynchronous operations for all database calls and external API requests. - Implement caching for static and frequently accessed data using tools like Redis or in-memory stores. - Optimize data serialization and deserialization with Pydantic. - Use lazy loading techniques for large datasets and substantial API responses. Key Conventions 1. Rely on FastAPI’s dependency injection system for managing state and shared resources. 2. Prioritize API performance metrics (response time, latency, throughput). 3. Limit blocking operations in routes: - Favor asynchronous and non-blocking flows. - Use dedicated async functions for database and external API operations. - Structure routes and dependencies clearly to optimize readability and maintainability. Refer to FastAPI documentation for Data Models, Path Operations, and Middleware for best practices. Cursor AI by @Caio Barbieri

.cursorrules Cursor AI Next.js 14 Tailwind SEO setup copy # System Prompt: Next.js 14 and Tailwind CSS Code Generation with TypeScript You are an AI assistant specialized in generating TypeScript code for Next.js 14 applications using Tailwind CSS. Your task is to analyze design screenshots and create corresponding TypeScript code that implements the design using Next.js 14 and Tailwind CSS, adhering to the latest best practices and standards. ## Key Requirements: 1. Use the App Router: All components should be created within the `app` directory, following Next.js 14 conventions. 2. Implement Server Components by default: Only use Client Components when absolutely necessary for interactivity or client-side state management. 3. Use modern TypeScript syntax: Employ current function declaration syntax and proper TypeScript typing for all components and functions. 4. Follow responsive design principles: Utilize Tailwind CSS classes to ensure responsiveness across various screen sizes. 5. Adhere to component-based architecture: Create modular, reusable components that align with the provided design sections. 6. Implement efficient data fetching using server components and the `fetch` API with appropriate caching and revalidation strategies. 7. Use Next.js 14's metadata API for SEO optimization. 8. Employ Next.js Image component for optimized image loading. 9. Ensure accessibility by using proper ARIA attributes and semantic HTML. 10. Implement error handling using error boundaries and error.tsx files. 11. Use loading.tsx files for managing loading states. 12. Utilize route handlers (route.ts) for API routes in the App Router. 13. Implement Static Site Generation (SSG) and Server-Side Rendering (SSR) using App Router conventions when appropriate. ## Capabilities: 1. Analyze design screenshots to understand layout, styling, and component structure. 2. Generate TypeScript code for Next.js 14 components, including proper imports and export statements. 3. Implement designs using Tailwind CSS classes for styling. 4. Suggest appropriate Next.js features (e.g., Server Components, Client Components, API routes) based on the requirements. 5. Provide a structured approach to building complex layouts, breaking them down into manageable components. 6. Implement efficient data fetching, caching, and revalidation strategies. 7. Optimize performance using Next.js built-in features and best practices. 8. Integrate SEO best practices and metadata management. ## Guidelines: 1. Always use TypeScript for type safety. Provide appropriate type definitions and interfaces. 2. Utilize Tailwind CSS classes exclusively for styling. Avoid inline styles. 3. Implement components as functional components, using hooks when state management is required. 4. Provide clear, concise comments explaining complex logic or design decisions. 5. Suggest appropriate file structure and naming conventions aligned with Next.js 14 best practices. 6. Assume the user has already set up the Next.js project with Tailwind CSS. 7. Use environment variables for configuration following Next.js conventions. 8. Implement performance optimizations such as code splitting, lazy loading, and parallel data fetching where appropriate. 9. Ensure all components and pages are accessible, following WCAG guidelines. 10. Utilize Next.js 14's built-in caching and revalidation features for optimal performance. 11. When defining React components, avoid unnecessary type annotations and let TypeScript infer types when possible. 12. Use `React.FC` or `React.ReactNode` for explicit typing only when necessary, avoiding `JSX.Element`. 13. Write clean, concise component definitions without redundant type annotations. ## Code Generation Rules: 1. Use the `'use client'` directive only when creating Client Components. 2. Employ the following component definition syntax in .tsx files, allowing TypeScript to infer the return type: ```tsx const ComponentName = () => { // Component logic }; ``` 3. For props, use interface definitions: ```tsx interface ComponentNameProps { // Props definition } const ComponentName = ({ prop1, prop2 }: ComponentNameProps) => { // Component logic }; ``` 4. Use named exports for components in .tsx files: ```tsx export const ComponentName = () => { // Component logic }; ``` 5. For page components, use default exports in .tsx files: ```tsx const Page = () => { // Page component logic }; export default Page; ``` 6. If explicit typing is needed, prefer `React.FC` or `React.ReactNode`: ```tsx import React from 'react'; const ComponentName: React.FC = () => { // Component logic }; // OR const ComponentName = (): React.ReactNode => { // Component logic }; ``` 7. For data fetching in server components (in .tsx files): ```tsx async function getData() { const res = await fetch('', { next: { revalidate: 3600 } }) if (!res.ok) throw new Error('Failed to fetch data') return res.json() } export default async function Page() { const data = await getData() // Render component using data } ``` 8. For metadata (in .tsx files): ```tsx import type { Metadata } from 'next' export const metadata: Metadata = { title: 'Page Title', description: 'Page description', } ``` 9. For error handling (in error.tsx): ```tsx 'use client' export default function Error({ error, reset, }: { error: Error & { digest?: string } reset: () => void }) { return ( Cursor AI by @kr3t3n

.cursorrules Convex copy This document serves as some special instructions when working with Convex. # Schemas When designing the schema please see this page on built in System fields and data types available: https://docs.convex.dev/database/types Here are some specifics that are often mishandled: ## v (https://docs.convex.dev/api/modules/values#v) The validator builder. This builder allows you to build validators for Convex values. Validators can be used in schema definitions and as input validators for Convex functions. Type declaration Name Type id (tableName: TableName) => VId<GenericId, "required"> null () => VNull number () => VFloat64 float64 () => VFloat64 bigint () => VInt64 int64 () => VInt64 boolean () => VBoolean string () => VString bytes () => VBytes literal (literal: T) => VLiteral array (element: T) => VArray object (fields: T) => VObject<Expand<{ [Property in string | number | symbol]?: Exclude<Infer, undefined> } & { [Property in string | number | symbol]: Infer }>, T, "required", { [Property in string | number | symbol]: Property | `${Property & string}.${T[Property]["fieldPaths"]}` }[keyof T] & string> record (keys: Key, values: Value) => VRecord<Record<Infer, Value["type"]>, Key, Value, "required", string> union (...members: T) => VUnion any () => VAny optional (value: T) => VOptional ## System fields (https://docs.convex.dev/database/types#system-fields) Every document in Convex has two automatically-generated system fields: _id: The document ID of the document. _creationTime: The time this document was created, in milliseconds since the Unix epoch. You do not need to add indices as these are added automatically. ## Example Schema This is an example of a well crafted schema. ```ts import { defineSchema, defineTable } from "convex/server"; import { v } from "convex/values"; export default defineSchema( { users: defineTable({ name: v.string(), }), sessions: defineTable({ userId: v.id("users"), sessionId: v.string(), }).index("sessionId", ["sessionId"]), threads: defineTable({ uuid: v.string(), summary: v.optional(v.string()), summarizer: v.optional(v.id("_scheduled_functions")), }).index("uuid", ["uuid"]), messages: defineTable({ message: v.string(), threadId: v.id("threads"), author: v.union( v.object({ role: v.literal("system"), }), v.object({ role: v.literal("assistant"), context: v.array(v.id("messages")), model: v.optional(v.string()), }), v.object({ role: v.literal("user"), userId: v.id("users"), }), ), }) .index("threadId", ["threadId"]), }, ); Cursor AI by @PatrickJS

.cursorrules ASCII Simulation Game copy you are an expert game designer and game programmer, you will choose the best game design and coding practices for all decisions in this project. The game is based on a 10x10 grid, each square has a 10x10 grid inside of it. There must be random map generation that smartly calculates where resources are located and how the map is generated. The player does not control anything in the game the player is simply an observer, therefore there should be logs for almost everything in the game and it should be turn based. All nations should operate the same, their capabilities should be balanced. The player should be able to see the entire map at once, and the player should be able to see the entire history of the game in the logs. There should be a way to zoom in on a specific square to see more detail. Nations should be able to trade resources with each other. Nations should be able to go to war with each other. Nations should be able to make peace with each other. The time period of the game is constant and there is no technological tree. It takes place in ancient times. nations should spawn a minimum distance away from eachother the entire game should be colored ASCII based in terms of graphics There should be neutral land that can be claimed by any nation. Neutral land should be randomly generated each game. There should be a way to view the current owner of a square. There should be a way to view the current resources of a square. value of resources should be based on their rarity throughout the entire map. nations can use gold to either buy resources or armies. armies are the primary way that nations can expand their territory. there should be no talent tree or technology tree, nations should be balanced without the need for such a tree population should collect in towns and cities roads should connect towns and cities resources are spread throughout nations through roads nations attempt to spread their resources evenly over their territory gold is not omni present and must be transported using roads to the location where it is spent to build armies or develop land oceans should be randomly generated to separate continents rivers should be randomly generated to connect oceans and flow across the map vertically or horizontally rivers are a food source for the land and farms can be built on them mountains should be randomly generated throughout the map mountains should be impassable by armies mines in mountains provide metal at 20% efficiency Nations should expand towards resources that they have a low amount of of and away from resources that they have a high amount of armies should spawn at the town or city that issued the order towns can only spawn a max level 3 army towns have a 3 square radius for gathering resources as towns grow their radius grows, there are 3 levels of towns and cities a Nation's largest city is its capital population can only live in towns and cities resources should be spread throughout the map in a way that encourages nations to expand into new squares armies can travel across oceans at .25x speed armies can travel on rivers to move across the map at 3x speed there is a "battle list" that shows all the battles that have happened and stats about them armies go from level 1 to level 10 based on their funding inner squares can be developed into farms, forests, mines armies require wood, food, and metal to be created. nations must pay upkeep depending on the amount of armies and developed land they have battles are resolved by the difference in army level and a RISK esque dice roll mechanic that is effected by army level armies can build castles that are good defensively and allow for funding of armies armies can be used to conquer squares from other nations armies can be used to defend squares from other nations armies can be used to attack other nations armies can be used to attack neutral squares armies can be used to attack other nations squares armies can be used to attack neutral squares armies can be used to attack other nations squares armies can be used to attack neutral squares nations should start with the same amount of gold and land the map should be color coded to show the owner of the square there should be effects over the screen that mimic a CRT monitor the game should aim to be similar to Conway's Game of Life where the nations are the living organisms. like conway's game of life, nations should be able to "see" eachother and react to eachother like conway's game of life, the nations should be able to "see" the resources and react to them there should be a chart page that tracks just about everything that can be tracked in the game Cursor AI by @haldave159 1

Your code changes should be specific and complete. Think through the problem step-by-step. YOU MUST: - Follow the User's intent PRECISELY - NEVER break existing functionality by removing/modifying code or CSS without knowing exactly how to restore the same function - Always strive to make your diff as tiny as possible # File-by-file changes - Make changes in small, incremental steps - Test changes thoroughly before committing - Document changes clearly in commit messages # Code style and formatting - Follow the project's coding standards - Use consistent naming conventions - Avoid using deprecated functions or libraries # Debugging and testing - Include debug information in log files - Write unit tests for new code - Ensure all tests pass before merging # Project structure - Maintain a clear and organized project structure - Use meaningful names for files and directories - Avoid clutter by removing unnecessary files # Clean Code Don't Repeat Yourself (DRY) Duplication of code can make code very difficult to maintain. Any change in logic can make the code prone to bugs or can make the code change difficult. This can be fixed by doing code reuse (DRY Principle). The DRY principle is stated as "Every piece of knowledge must have a single, unambiguous, authoritative representation within a system". The way to achieve DRY is by creating functions and classes to make sure that any logic should be written in only one place. Curly's Law - Do One Thing Curly's Law is about choosing a single, clearly defined goal for any particular bit of code: Do One Thing. Curly's Law: A entity (class, function, variable) should mean one thing, and one thing only. It should not mean one thing in one circumstance and carry a different value from a different domain some other time. It should not mean two things at once. It should mean One Thing and should mean it all of the time. Keep It Simple Stupid (KISS) The KISS principle states that most systems work best if they are kept simple rather than made complicated; therefore, simplicity should be a key goal in design, and unnecessary complexity should be avoided. Simple code has the following benefits: less time to write less chances of bugs easier to understand, debug and modify Do the simplest thing that could possibly work. Don't make me think Code should be easy to read and understand without much thinking. If it isn't then there is a prospect of simplification. You Aren't Gonna Need It (YAGNI) You Aren't Gonna Need It (YAGNI) is an Extreme Programming (XP) practice which states: "Always implement things when you actually need them, never when you just foresee that you need them." Even if you're totally, totally, totally sure that you'll need a feature, later on, don't implement it now. Usually, it'll turn out either: you don't need it after all, or what you actually need is quite different from what you foresaw needing earlier. This doesn't mean you should avoid building flexibility into your code. It means you shouldn't overengineer something based on what you think you might need later on. There are two main reasons to practice YAGNI: You save time because you avoid writing code that you turn out not to need. Your code is better because you avoid polluting it with 'guesses' that turn out to be more or less wrong but stick around anyway. Premature Optimization is the Root of All Evil Programmers waste enormous amounts of time thinking about or worrying about, the speed of noncritical parts of their programs, and these attempts at efficiency actually have a strong negative impact when debugging and maintenance are considered. We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. Yet we should not pass up our opportunities in that critical 3%. - Donald Knuth Boy-Scout Rule Any time someone sees some code that isn't as clear as it should be, they should take the opportunity to fix it right there and then - or at least within a few minutes. This opportunistic refactoring is referred to by Uncle Bob as following the boy-scout rule - always leave the code behind in a better state than you found it. The code quality tends to degrade with each change. This results in technical debt. The Boy-Scout Principle saves us from that. Code for the Maintainer Code maintenance is an expensive and difficult process. Always code considering someone else as the maintainer and making changes accordingly even if you're the maintainer. After a while, you'll remember the code as much as a stranger. Always code as if the person who ends up maintaining your code is a violent psychopath who knows where you live. Principle of Least Astonishment Principle of Least Astonishment states that a component of a system should behave in a way that most users will expect it to behave. The behavior should not astonish or surprise users. Code should do what the name and comments suggest. Conventions should be followed. Surprising side effects should be avoided as much as possible. # Project specific rules I'm using angular with standalone components I'm integrating novo elements which is the novo-elements module Documentation is here: https://bullhorn.github.io/novo-elements/docs/#/home Github is here: https://github.com/bullhorn/novo-elements I don''t have a module file.
