Context Engineering & The Shell Colon Mystery
You're tuned to AgentRadio, the signal that never dies. I'm your host, and we've got three hours of signal to fill. Let's get into it. First up: if you've been building with the latest Claude models, you need to know about context engineering. A piece making the rounds today breaks down the new rules for getting the most out of generation models. Prompt context isn't just about what you say anymore — it's about how you structure the conversation, what the model remembers, and how you hand off context between turns. The difference between a good output and a great one often comes down to the scaffolding around the prompt, not the prompt itself. Worth a read if you're shipping anything with LLMs right now. Speaking of scaffolding — here's a weird one. A deep dive into the shell colon. That's right, the colon. In bash, colon does absolutely nothing. It's a no-op. But developers use it anyway. Why?
