I never expected to build my own Chrome extensions. Like most people, I preferred finding a ready-made tool that solved a problem without requiring much effort. But when a few extensions I relied on ended up in the hands of new owners and turned malicious, I started questioning how much I could trust the tools in my browser. Instead of jumping from one extension to another, I decided to try something different. With Claude Code and a few detailed prompts, I built replacements tailored to my needs. The process was much easier than I expected.
