Maximizing Your AI Assistant: Best Practices from the Trenches

Getting an AI coding tool is just the beginning. Using it effectively requires developing new skills and workflows. Here’s what I’ve learned from hundreds of hours working with these platforms:

Master the Art of Prompting

Treat your AI like a talented junior developer—eager and fast, but needing clear direction.

Ineffective: “Write a function to validate user input.” Effective: “Write a TypeScript function using Zod that validates a user registration object with email (valid format), password (8+ chars, 1 number, 1 special char), and age (18+). Return validated object or throw descriptive errors.”

Never Trust, Always Verify

AI-generated code can contain subtle bugs, security vulnerabilities, or inefficient patterns. Research shows developers using AI sometimes write less secure code due to over-reliance on suggestions. You’re still the engineer of record—never commit code you can’t explain and defend.

Use AI for Drudgery, Save Brain Power for Architecture

Let AI handle the repetitive work: generating boilerplate, writing tests, creating documentation, and scaffolding projects. This frees your mental energy for high-value tasks: system design, complex business logic, and strategic technical decisions.

Master Context Control

AI output quality correlates directly with context quality. Learn your tool’s context management features—Cursor’s @ mentions, JetBrains’ explicit context selection, or simply organizing your workspace thoughtfully. Better context yields dramatically better results.

Embrace Iterative Refinement

Don’t expect perfection from a single prompt. Treat AI like a collaborative partner. Generate a first draft, then refine through conversation: “Good start, but refactor this into smaller functions,” “Add comprehensive error handling,” “What are the performance implications here?”

FAQ: Your Burning Questions Answered
