Coding harness is not a moat, but Anthropic’s productivity integrations are starting to be at my company. Surveys, checklists that Claude and people collaborate on, draft documents where you @ Claude to ask for revisions.

I’m not convinced it’s durable or that Anthropic will be the ones to change the document habits people have decades in… but it is a mistake to only see these companies in terms of models and coding/chat harnesses. There is something a lot bigger there.
