AI Coding Prompts

Write a [language] function that [describe behavior]. Requirements: handle these edge cases: [list them], include input validation, add JSDoc/docstring with parameter descriptions, use [naming convention]. Return type: [specify]. Throw meaningful errors, don't return null silently.

Refactor this code to improve readability without changing behavior. Focus on: extracting well-named helper functions, reducing nesting depth, replacing magic numbers with named constants, and simplifying conditionals. Explain each change. [paste code]

Write a REST API endpoint in [framework] that [describe operation]. Include: input validation with error messages, proper HTTP status codes, error handling middleware, rate limiting logic, and a brief OpenAPI/Swagger comment. Use [authentication method] for auth.

Optimize this database query for performance: [paste query]. Current execution time: [if known]. Table sizes: [approximate rows]. Indexes available: [list them]. Explain: why it's slow, what the query plan likely looks like, and provide an optimized version with expected improvement.

Convert this [source language] code to idiomatic [target language]. Don't just translate syntax - use the target language's native patterns, standard library, and best practices. Note any functionality that doesn't have a direct equivalent and how you handled it. [paste code]
