# Cursor Prompt Library — TrendForge Copy-paste prompts for common development tasks. Adjust paths and names to match your project. --- ## Bug Fixing ``` There's a bug in [describe symptom]. Search the codebase for the relevant files, identify the root cause, fix it with minimal changes, and run the existing tests. Explain what caused the bug before making edits. ``` ``` The error "[paste error message]" appears when [describe steps to reproduce]. Trace the call stack, find where the error originates, and fix it without changing unrelated code. ``` --- ## Refactoring ``` Refactor [file/module path] to improve readability and maintainability. Keep all existing behavior and public APIs unchanged. Run tests after refactoring. ``` ``` Extract repeated logic from [files] into a shared utility. Update all call sites. Do not change functionality — only reduce duplication. ``` --- ## New Features ``` Implement [feature description] following our project conventions in .cursor/rules/. Break the work into steps, search the codebase for similar patterns first, then implement with tests. ``` ``` Add a [ComponentName] component that [behavior]. Use TypeScript, match existing styling patterns, and include loading/error/empty states. ``` --- ## Code Review ``` Review the changes in my working tree. Check for bugs, security issues, missing error handling, and violations of our project rules. List findings by severity. ``` ``` Review [file path] for performance issues, accessibility problems, and TypeScript type safety. Suggest specific fixes. ``` --- ## Testing ``` Write unit tests for [file/function] using our project's test framework. Cover happy path, error cases, and edge cases. Mock external dependencies. ``` ``` The tests in [test file] are failing. Read the failure output, fix the tests or the implementation (whichever is wrong), and confirm all tests pass. ``` --- ## Documentation ``` Generate API documentation for all routes in [directory]. Include request/response schemas, status codes, and example payloads in Markdown. ``` ``` Add JSDoc comments to all exported functions in [file]. Document parameters, return types, and throw conditions. ``` --- ## Database & API ``` Create a migration for [schema change description]. Include rollback. Follow our existing migration patterns in [migrations directory]. ``` ``` Add a new API endpoint: [method] [path] that [behavior]. Validate inputs, return consistent JSON errors, and add a feature test. ``` --- ## DevOps & Deployment ``` Review our deployment configuration and suggest improvements for [Cloudflare/Vercel/AWS]. Check environment variables, build commands, and caching. ``` ``` Set up a GitHub Actions workflow that runs lint, type-check, and tests on every pull request. ``` --- ## Repository Understanding ``` Give me an architecture overview of this repository: folder structure, key modules, data flow, and tech stack. Point to the most important files to read first. ``` ``` Explain how [feature/system name] works in this codebase. Trace the code from entry point to output. ``` --- ## Dependency Updates ``` Update [package name] to the latest compatible version. Check for breaking changes, update any affected code, and run the test suite. ``` --- ## Security ``` Audit [file/directory] for common security issues: SQL injection, XSS, exposed secrets, insecure dependencies, and missing input validation. Report findings with fixes. ``` --- Part of the [Cursor AI Complete Guide (2026)](https://trendforge.pages.dev/article/ai/cursor-ai-complete-guide-2026) on TrendForge.
