@jonny "So the reason that Claude code is capable of outputting valid json is because if the prompt text suggests it should be JSON then it enters a special loop in the main query engine that just validates it against JSON schema for JSON and then feeds the data with the error message back into itself until it is valid JSON or a retry limit is reached."

This is how LLMs do *anything* even remotely approaching accurate or reliable work. They offload it to an actual deterministic algorithm. The man behind the curtain. It's frustrating how people don't seem to realize this, I hope it becomes more common knowledge!

💜 A year ago today we lost one of the kindest, most-generous developers in the Mac community, Martin Pilkington (pilky). He was known for and worked on many projects over the years, but Coppice was his labor of love. I have been working the past couple of months on rebuilding Coppice for macOS 26, Liquid Glass, and the App Store, and I'm thrilled that today is the day I get to release it into the world — with all of its previously-'Pro' features available for free
