Reading the July stateless architecture change properly rather than skimming the announcement. The practical consequence for anyone building a server: you can scale horizontally behind ordinary HTTP with no session affinity, which removes most of the operational argument against exposing one.

Notes and the sections that actually matter, rather than the whole document.

The part I keep returning to is that tool descriptions are the interface now. A badly described tool is a broken tool, and no amount of correct implementation fixes it.

We spend a lot of effort on schemas and almost none on the prose, and the prose is what the caller reads.
