What I mean is just a modest effort to guide the model up front is adequate for the full end to end session -- one-shotting, basically. I used to go through planning mode prior to 5.5, to make sure it understood my intentions but I no longer need to. I just ramble off the desired outcome and some broad architectural guidelines into wisprflow, hit enter, answer any questions it has and then a PR that tends to only get minor feedback is produced. It's basically fire and forget.
As in, many if not most reviewers have always been nothing more than approvers, i.e. people that click the approve button with minimal to zero review, maybe a "pro forma" comment so nobody has them show up in some statistic as "only clicks the approve button".
With the amount of AI generated PRs this will have tended to become more of a problem, not less.
