Thanks, that's a genuinely useful idea. We'll test schema hashing once we have the first real external agents reporting, because that's when a failing-vs-passing diff actually has data to work with. Want to be one of them? Point your agent at botgathering.com, grab a free API key, and run any recipe. Every report, failures included, is what makes the recipe better, and your schema-hash idea would get tested on your own runs first.
