Cursor Coding

Best Cursor AI Prompts for Coding (2026)

Cursor is an AI-native IDE that understands your entire codebase — not just the current file. These prompts are designed for Cursor's chat sidebar (Cmd+L), inline editing (Cmd+K), and background agent mode. They cover codebase exploration, multi-file refactoring, test generation, and debugging across large repositories. Optimised for Cursor Pro with Claude Fable 5 or GPT-5.6 Sol as the backing model.

Explore the Codebase (Cmd+L)

Get oriented in an unfamiliar codebase quickly

[USE IN CURSOR CHAT SIDEBAR] Help me understand this codebase. Please: 1. Describe the overall architecture and folder structure 2. Explain the main data flow from [ENTRY POINT] to [OUTPUT] 3. Identify the most important files and what each does 4. Flag any patterns or conventions used throughout 5. Note anything that looks like technical debt or unusual choices

Implement a Feature (Agent Mode)

Delegate a complete feature to Cursor background agent

[USE IN CURSOR BACKGROUND AGENT] Implement the following feature: Feature: [DESCRIBE IN DETAIL] Files to modify: [LIST OR SAY "you decide"] Files to NOT touch: [LIST] Tests required: [YES / NO] Definition of done: [HOW WILL WE KNOW IT IS COMPLETE] Work through this step by step. Commit each logical change separately.

Fix a Bug Across Multiple Files

Trace and fix bugs that span multiple files

[USE IN CURSOR CHAT WITH RELEVANT FILES OPEN] I have a bug: [DESCRIBE THE BUG] I think it might be related to: - [FILE 1] - [FILE 2] - [FILE 3] Please: 1. Trace the bug through the relevant code 2. Identify the exact root cause 3. Show the fix in each affected file 4. Confirm the fix with a test or manual verification step

Refactor with Codebase Context (Cmd+K)

Refactor code using patterns from the rest of the codebase

[HIGHLIGHT CODE THEN USE CMD+K] Refactor this code to: [DESCRIBE THE REFACTORING GOAL] Constraints: - Do not break the public interface - Keep the same behavior - Apply the patterns used elsewhere in this codebase If you need context from other files, ask.

Write Tests for This File

Generate tests that match your existing codebase patterns

[USE IN CURSOR CHAT WITH TEST FILE OPEN] Write comprehensive tests for [FILE NAME]. Use [JEST / VITEST / PYTEST — specify]. Cover: - All exported functions - Happy path for each - At least 2 edge cases per function - Error states Use the mocking patterns already established in this codebase.

Explain a Complex Function

Understand any complex function with codebase context

[USE IN CURSOR CHAT WITH FILE OPEN] Explain the following function to me as a mid-level engineer new to this codebase: [HIGHLIGHT FUNCTION OR PASTE IT] 1. What does it do in plain English? 2. What are the inputs and outputs? 3. What edge cases does it handle? 4. Why was it written this way? 5. Are there any gotchas I should know?
