Code Generation That Actually Works

How to prompt AI for production-quality code, not just snippets.

The difference between garbage AI code and production-quality AI code comes down to one thing: context. The more context you give about your codebase, constraints, and standards, the better the output.

  1. Language & framework: "TypeScript with Next.js 15 App Router"
  2. Existing patterns: "We use server components by default, client only when needed"
  3. Error handling: "Use try/catch with typed errors, never silent catches"
  4. Testing: "Include unit tests with Vitest"
  5. Style: "Follow existing codebase conventions" (paste an example)

Feature Implementation

Generates production-quality code with your codebase patterns.

Implement [FEATURE DESCRIPTION].

Tech stack: [LANGUAGE/FRAMEWORK]
Existing patterns to follow:
```
[PASTE EXAMPLE OF SIMILAR CODE FROM YOUR CODEBASE]
```

Requirements:
- [Requirement 1]
- [Requirement 2]
- [Requirement 3]

Constraints:
- Must handle: [error cases]
- Must not: [anti-patterns to avoid]
- Performance: [any performance requirements]

Include:
- The implementation
- Error handling
- Input validation
- TypeScript types/interfaces
- Brief inline comments for complex logic only
Always paste a real example from your codebase. AI mimics patterns — if you show it good patterns, it produces good code. If you give no context, it defaults to tutorial-quality code.

Code Review

Thorough code review catching bugs, security issues, and performance problems.

Review this code for:
1. Bugs or logic errors
2. Security vulnerabilities (injection, XSS, etc.)
3. Performance issues
4. Missing error handling
5. Code style improvements

Be specific: point to exact lines and explain the issue and fix.
Don't suggest style changes unless they impact readability.
Assume this is production code.

```[LANGUAGE]

Debug This

Focused debugging that finds the root cause.

This code has a bug. The expected behavior is [EXPECTED]. The actual behavior is [ACTUAL].

Error message (if any): [ERROR]

Code:
```
[CODE]
```

Don't rewrite the whole thing. Find the specific bug, explain why it happens, and show the minimal fix.

Key Takeaways

  • Context is the difference between tutorial code and production code
  • Always include existing codebase examples in your prompts
  • Specify constraints and anti-patterns, not just requirements
  • Code review prompts should explicitly list what to check for
