In general, we've found that over the past couple of years agent harnesses have gotten much less restrictive, allowing the agent freedom to choose its own way of doing things. It seems like the project agnostic vs. specific harnesses will follow that trend. The pattern will work well for the current gen models, but eventually Fable 7 will be able to intuit how it should approach a specific project very well, at which point the challenge is making sure it has the tools to do so.

And I've made some changes to the coupon, does it work now?
