{"slug": "stop-cursor-ai-from-writing-broken-code", "title": "Stop Cursor AI From Writing Broken Code", "summary": "A developer warns that Cursor AI and similar coding tools often produce broken code because they lack project context. The solution is to provide a complete system architecture—including tech stack, database schema, and folder structure—before generating code, and to break development into separate phases for UI, logic, and data. This approach reduces AI hallucinations and debugging time.", "body_md": "If you've spent more than a few hours building apps with Cursor or Replit AI, you've probably seen this happen.\n\nYou ask the AI to build a feature.\n\nInstead, it:\n\nSound familiar?\n\nYou're not alone.\n\nThe biggest mistake most developers make isn't using Cursor. It's asking Cursor to code before giving it a proper architecture.\n\nCursor is incredibly good at writing code.\n\nBut it's terrible at guessing your project structure.\n\nWhen the AI doesn't know:\n\nit starts making assumptions.\n\nThose assumptions become:\n\nThis is why people think Cursor is \"hallucinating.\"\n\nMost of the time, it's simply missing context.\n\nThink of Cursor as a junior software engineer.\n\nWould you tell a junior developer:\n\n\"Go build my entire SaaS app.\"\n\nOf course not.\n\nYou'd first provide:\n\nOnly then would they start coding.\n\nAI code builders work exactly the same way.\n\nThey perform dramatically better when they're given a complete system architecture before generating a single file.\n\nThat one change eliminates a surprising number of AI-generated bugs.\n\nInstead of asking Cursor to \"build the app,\" break the process into three phases.\n\nBefore writing any code, document the foundation.\n\nInclude things like:\n\nExample:\n\n```\nFrontend:\n- Next.js\n- TypeScript\n- Tailwind CSS\n\nBackend:\n- Node.js\n- Express\n\nDatabase:\n- PostgreSQL\n- Prisma ORM\n\nAuthentication:\n- Clerk\n\nHosting:\n- Vercel\n```\n\nThen define your database schema.\n\nExample:\n\n```\nUsers\n- id\n- email\n- password_hash\n- created_at\n\nProjects\n- id\n- user_id\n- title\n- created_at\n\nTasks\n- id\n- project_id\n- title\n- completed\n```\n\nNow Cursor understands what data exists before it starts inventing tables.\n\nThis step is skipped surprisingly often.\n\nThat's exactly why AI starts dumping files into the root directory.\n\nInstead, define the project layout first.\n\nExample:\n\n```\nsrc/\n├──components/\n├──pages/\n├──hooks/\n├──services/\n├──lib/\n├──utils/\n├──types/\n├──styles/\n├──database/\n├──prisma/\n├──api/\n├──tests/\n```\n\nAlso define rules such as:\n\nShared components belong in components/\n\nAPI logic stays inside services/\n\nDatabase code only lives in database/\n\nUtility functions stay inside utils/\n\nThis removes a huge amount of ambiguity.\n\nThe AI no longer has to guess where new files belong.\n\nThis is the biggest improvement you can make.\n\nNever ask Cursor to build everything at once.\n\nInstead, split development into separate prompts.\n\nPrompt only for:\n\nDon't mention authentication.\n\nDon't mention APIs.\n\nDon't mention databases.\n\nJust the interface.\n\nOnce the UI is complete, move to:\n\nSince the UI already exists, Cursor has a stable target to connect everything to.\n\nOnly after the app structure is stable should you implement:\n\nEach phase builds on the previous one.\n\nNothing gets rewritten unnecessarily.\n\nLarge Language Models have limited working memory.\n\nThe more unrelated tasks you ask them to solve simultaneously, the more likely they are to:\n\nBreaking development into clear phases reduces complexity.\n\nInstead of solving twenty problems at once, the AI solves one well-defined problem at a time.\n\nThe result is cleaner code, fewer regressions, and a much smoother development experience.\n\nAvoid prompts like :\n\nBuild a complete production-ready SaaS with authentication, payments, dashboard, admin panel, AI chat, Stripe, email verification, analytics, and deployment.\n\nThat's too many responsibilities in one request.\n\nA better prompt is:\n\nBuild only the dashboard UI using the provided architecture. Do not create authentication, APIs, or database code. Follow the directory structure exactly.\n\nThe second prompt is far more constrained, which makes the output more reliable.\n\nDon't ask AI to design and build at the same time.\n\nFirst, give it the blueprint.\n\nThen let it write the code.\n\nThat small change can save hours of debugging and reduce the chances of Cursor getting stuck in repetitive fix loops.\n\nThe PromptBase collection includes structured prompts designed to help Cursor, Replit Agent, Bolt.new, and similar AI coding tools generate cleaner, more maintainable projects with fewer architectural mistakes.\n\nAI-assisted development is evolving quickly, but the fundamentals of software engineering haven't changed.\n\nGood architecture still comes before good code.\n\nThe better your specifications, folder structure, and implementation plan, the better your AI-generated output will be.\n\nCursor isn't failing because it's incapable.\n\nIt's usually failing because it's being asked to improvise an entire software architecture while simultaneously writing the implementation.\n\nGive it a plan first.\n\nThen let it build.\n\nHow do you structure your Cursor or Replit workflow?\n\nDo you use architecture documents, phased prompts, or another system that keeps AI from going off the rails?\n\nShare your workflow in the comments—I'd love to see what has worked for you.", "url": "https://wpnews.pro/news/stop-cursor-ai-from-writing-broken-code", "canonical_source": "https://dev.to/gagan_builds/stop-cursor-ai-from-writing-broken-code-1h0d", "published_at": "2026-07-23 06:00:42+00:00", "updated_at": "2026-07-23 06:30:53.216287+00:00", "lang": "en", "topics": ["developer-tools", "artificial-intelligence", "large-language-models"], "entities": ["Cursor", "Replit AI", "PromptBase", "Next.js", "TypeScript", "Tailwind CSS", "Node.js", "Prisma"], "alternates": {"html": "https://wpnews.pro/news/stop-cursor-ai-from-writing-broken-code", "markdown": "https://wpnews.pro/news/stop-cursor-ai-from-writing-broken-code.md", "text": "https://wpnews.pro/news/stop-cursor-ai-from-writing-broken-code.txt", "jsonld": "https://wpnews.pro/news/stop-cursor-ai-from-writing-broken-code.jsonld"}}
