Agents, skills etc. Stuff that's specific to the Claude CLI tooling and not the model.

Sonnet 4.5 as a raw model is good, but what makes it great is the tool that calls it.

Think of it like this: Sonnet 4.5 is the engine, but the whole car around it matters a LOT.

Copilot is kinda crap as a LLM tool, the tool calling permissions are clunky, it doesn't support sub agents or skills or anything fancy really. The best thing about it is that it can see the "problems" tab on VSCode provided by different addons and linters and you can tell an agent "fix the active problems" and it'll get to work.
