The Ultimate Guide to Prompt Engineering for Developers
Introduction
AI-assisted coding is no longer optional. 92% of developers have tried an LLM tool. The ones who get the best results understand prompt engineering.
This guide covers generating code, debugging, writing documentation, building test suites, and code reviews — all through structured prompting.
STCO for Development
Situation = your tech stack and codebase context. Task = the specific coding task. Constraints = language, framework, patterns, error handling. Output = code format, tests, documentation.
Review this code and find bugsSystem: You are a senior software engineer conducting a code review. You specialise in TypeScript, React, and Node.js.
Task: Review the following React component for bugs, performance issues, and best practice violations.
Context:
- Framework: React 18 with TypeScript
- The component renders a paginated list of 1000+ items
- It's currently causing re-renders on every keystroke
Output: Return a numbered list of issues with severity, description, fix snippet, and explanation.Why this matters: Specifying the tech stack, the exact problem symptoms, and the desired output format gives the AI enough context to deliver actionable, senior-level code review feedback.
