True for coding agents running SotA models where you're the human-in-the-loop approving, less true for your deployed agents running on cheap models that you don't see what's being executed.

But yeah, a concrete example is playwright-mcp vs playwright-cli: https://testcollab.com/blog/playwright-cli

Probably oversold here because if you read the fine print, the savings only come in cases when you don't need the bytes in context.

That makes sense for some of the examples the described (e.g. a QA workflow asking the agent to take a screenshot and put it into a folder).

However, this is not true for an active dev workflow when you actually do want it to see that the elements are not lining up or are overlapping or not behaving correctly. So token savings are possible...if your use case doesn't require the bytes in context (which most active dev use cases probably do)*

This is cool!

I was actually thinking if I should support daemons just to support playwright. Now I don't have a use case for it
