As a web developer, I’ve found AI coding assistants to be powerful allies—when I prompt them correctly. This article is for programmers, web developers, and software engineers who want to harness AI tools efficiently, whether they’re building apps, debugging code, or exploring new features. Drawing from my work on a notetaking app (React, TypeScript, Tailwind CSS), I’ll share best practices that have worked for me, pitfalls to avoid, and resources to get started.

Best Practices for AI Coding Prompts

Provide Comprehensive Context
AI needs context to deliver relevant code. When adding a tag filter to my notetaking app’s NoteList.tsx, I include the full file, my stack (React, Tailwind), and the app’s purpose (note CRUD with tags).
- How: Submit key files and details: “I’m building a notetaking app with React and Tailwind. Here’s NoteList.tsx. Add a tag filter.
- Why: Context ensures the AI aligns with your project’s structure.
Specify Requirements Clearly
Ambiguity leads to unusable output. I ask for “full code, no TypeScript errors” when modifying NoteItem.tsx to add a delete button, getting a complete working solution.
- How: Define the task precisely: “Add a delete button to NoteItem.tsx, full code, no TypeScript errors.”
- Why: Clear instructions reduce guesswork and revisions.
Share Project Goals
Including goals helps the AI prioritize. For my NoteEditor.tsx, I specify “intuitive quick edits,” and it suggests autosave and Markdown support.
- How: State objectives: "Optimize NoteList.tsx for mobile scroll performance."
- Why: Goals guide the AI to meet user-focused outcomes.
Include Debugging Details
When my note deletion failed, I provide “delete button in NoteItem.tsx throws the error: Cannot read property ‘id’ of undefined with checks (e.g. “DB’s fine”). This speeds up fixes.
- How: Share errors and steps: "Getting TypeError in NoteForm.tsx, checked props, no typos."
- Why: Details pinpoint issues for faster resolution.
Request Complete Solutions
I prefer full components over snippets. Asking for “full NoteList.tsx with sorting” saves integration time.
- How: Require entirety: "Rewrite NoteEditor.tsx with autosave, full code."
- Why: Complete code minimizes manual assembly.
Iterate on Responses
I refine prompts iteratively. Starting with “Help with NoteForm.tsx” I follow up with “It’s saving blank notes - here’s the API log” for a quick fix.
1. How: Start broad, then narrow: "Debug NoteItem.tsx" then clarify with logs.
2. Why: Iteration refines results through dialogue.

Common Pitfalls to Avoid

Vague Requests:
- Pitfall: "Make my app better" yields irrelevant changes.
- Fix: "Add a dark mode toggle to NoteList.tsx with Tailwind."
Missing Context:
- Pitfall: "Fix this" without code leads to generic guesses.
- Fix: "Here’s NoteForm.tsx, fix the submit bug."
Assuming Knowledge:
- Pitfall: Expecting AI to know my CSS vars results in mismatches.
- Fix: "Use globals.css vars like --primary-btn-bg."
Ignoring Clarifications:
- Pitfall: Not answering "What’s the error?" stalls progress.
- Fix: "Here’s the log you requested."
Unclear Scope:
- Pitfall: "Add a feature and more" risks overcomplication.
- Fix: "Just a delete button in NoteItem.tsx."
