The ULTIMATE AI Coding Guide for Developers (Claude Code)

Grab my CLAUDE.md file here: https://www.sabrina.dev/p/ultimate-ai...

How I use Claude Code, the ultimate AI coding tool, to implement new features in an existing complex codebase with many users. This is not a vibe coding tutorial building throwaway MVPs. This AI coding guide is for software developers who want to improve their daily AI coding workflows, maintain a clean codebase, and reduce bugs introduced by AI.

I walk through my CLAUDE.md file containing AI coding rules, then implement a real feature from scratch, following a structured step-by-step process. There is no AI tool that performs at a senior-level in 2025, so you'll still need to push back on Claude's plans, stop it from going down the wrong rabbit hole, question its code, and test extensively.
