Vibe coding is a development methodology where humans and AI iterate together in tight loops — humans provide intent and judgment, AI provides code and alternatives. This guide explains the principles, patterns, and pitfalls of building software this way.
AI tools accelerate test-driven development by generating test cases, implementing code to pass them, and suggesting edge cases humans miss. This guide shows how to integrate AI into a real TDD workflow with Python and JavaScript examples.
AI tools make large-scale code refactoring faster and safer by applying consistent transformations across a codebase. This guide covers the best refactoring patterns, tools, and how to verify AI-generated changes without breaking production code.
AI tools can generate accurate docstrings, README files, API reference documentation, and architecture guides from code. This guide shows how to use AI to keep documentation current with practical prompts and Python/JavaScript examples.
AI tools can generate complex SQL queries from plain-English descriptions, optimize slow queries with index suggestions, and explain query execution plans. This guide covers practical workflows for PostgreSQL, MySQL, and SQLite with real examples.
AI tools can design RESTful API endpoints, generate OpenAPI specifications, identify inconsistencies in existing APIs, and write client SDK code. This guide covers practical workflows for backend developers using Python and Node.js.
AI tools dramatically speed up debugging by interpreting stack traces, identifying root causes in code, and suggesting targeted fixes. This guide covers the most effective AI debugging workflows with Python and JavaScript examples.
AI tools can identify SQL injection, XSS, insecure authentication, and other OWASP Top 10 vulnerabilities in code reviews. This guide covers how to use AI security review effectively, what it catches reliably, and where human expertise is still required.
AI tools accelerate DevOps work by generating Dockerfiles, GitHub Actions workflows, Kubernetes manifests, and Terraform configs from natural language descriptions. This guide covers practical DevOps AI workflows with real configuration examples.
ChatGPT Tools, GPT Actions, and custom GPTs let developers build specialized AI workflows for code review, data analysis, documentation generation, and more. This guide covers the most useful developer configurations and how to build your own.
