Whoa, this looks incredible.

Having built my company's MCP server, I have a deeper appreciation for how important well-defined tools can be. It is clear to me that tool availability and coordination is going to be a top (or THE top) focus in the near future, more important than the model itself.

If you ever look at how an LLM greps through a codebase, pulling small slices at a time to gather what it needs, you have a sense of how precise tools can broaden a model's capabilities. If I had today's Sonnet with tooling from 5 years in the future, I expect it would beat Fable 5.2 hands down - that's how dramatic the difference is.

Anthropic/OpenAI have really buried the lede about tooling, baking it into their harnesses and trying to force lock-in. We are still in the AOL days of the internet right now.
