Every developer I know is using AI now. But most are writing throwaway prompts — vague, inconsistent, and getting mediocre results.
I spent a few weeks refining the prompts I use daily into reusable templates. Here are 10 of the best ones. Just replace the [BRACKETED] parts with your specifics.
The Feature Builder
You are a senior software engineer. Write clean, production-ready [LANGUAGE] code for: [DESCRIPTION]. Include error handling, edge cases, and inline comments. Follow [FRAMEWORK] best practices.
Why it works: Assigning the "senior engineer" role consistently gets more thoughtful, production-quality output.The Bug Detective
This code produces unexpected behavior: [PASTE CODE]. Expected: [EXPECTED]. Actual: [ACTUAL]. Walk me through your debugging process step by step, identify the root cause, and provide a fix.
Why it works: Forcing step-by-step reasoning catches issues that a direct "fix this" prompt misses.Deep Code Reviewer
Review this code as a senior engineer at a top tech company: [PASTE CODE]. Evaluate: correctness, security, performance, readability, and test coverage. Prioritize issues as Critical / Medium / Low.
Why it works: The priority tiers mean you act on what matters instead of getting overwhelmed.Unit Test Generator
Write comprehensive unit tests for this function using [TEST FRAMEWORK]: [PASTE CODE]. Cover: happy path, edge cases, error conditions, boundary values, and null inputs. Add descriptive test names.Tech to Plain English
Explain this to a non-technical stakeholder: [CONCEPT/CODE]. Use a simple analogy, avoid jargon, and include a real-world business impact statement. Keep it under 150 words.
Why it works: Lifesaver before stakeholder demos.PR Description Writer
Write a pull request description for: [DESCRIBE CHANGES]. Include: what changed and why, how to test it, breaking changes, and a reviewer checklist.README Generator
Write a professional README.md for: [PROJECT DESCRIPTION]. Include: title, one-line description, features, tech stack, installation steps, usage examples, and contributing guide.Prompt Refiner
Improve this AI prompt for better, more consistent results: [ORIGINAL PROMPT]. Rewrite it with clear role assignment, specific output format, constraints, and examples.
Why it works: Meta-prompting. Use AI to make your AI prompts better.System Design Advisor
Design a scalable system for [USE CASE] handling [SCALE]. Cover: architecture, database choices, caching strategy, API design, and bottlenecks with solutions.CI/CD Pipeline Builder
Write a [GITHUB ACTIONS/GITLAB CI] pipeline for a [LANGUAGE/FRAMEWORK] app. Include: linting, testing, security scanning, build, and deployment with rollback.
These 10 are from a larger pack of 40 I put together — if you want the full toolkit with all 7 categories, I packaged it as a PDF here: [https://b4m.gumroad.com/l/wehfa]
