How I Built a Background English Coach into Claude Code

As some of you might know, I'm from Sri Lanka and English isn't my first language. So as a software engineer who basically lives inside Claude Code, typing 50+ prompts a day, you can imagine how many grammatically questionable sentences I produce. 😅 And I've lost count of how many times I've looked back at a prompt I just wrote and thought, "wow, that grammar is terrible." Or worse, the grammar is fine but the whole sentence just sounds unnatural. I can tell it sounds off. I know a native speaker wouldn't phrase it that way. But I don't have time to figure out what the actual error is, why it sounds weird, or how someone would naturally say it. I have code to ship, so I move on and tell myself I'll fix my English later. Later never comes. You know how it goes. 🤷‍♂️ But here's the thing. Those 50+ prompts I type every day? They're real English sentences. Not textbook exercises. Not "the cat sat on the mat." They're messy, fast, and authentic. And that's actually perfect practice materia
