It increasingly is. E.g. if you use Claude Code, you'll notice it "likes" to produce todo lists that rendered specially via the TodoWrite tool that's built in.

But it's also a balance of avoiding being over-prescriptive in tools that needs to support very different workflows, and it's easy to add more specific checks via plugins.

We're bound to see more packaged up workflows over time, but the tooling here is still in very early stages.
