Superpowers has stopped working the past six months, to the point where it’s actively harmful. The main problem is the Writing Plans skill — its directives emphasize that the plan must be written for agents that cannot be trusted. What happens is the agent then writes all the code and the steps become “Copy this code block into foo.rs”. Meanwhile the review skill specifies that the code must follow the plan exactly; but now that it’s at the level of copying code, which hasn’t been tested and compiled*, the reviewer always freaks out about a stray & or comma, launching fixer agents and whatnot.

The last straw was two weeks ago when I discovered on a run Fable accounted for this problem in by first writing all the code in a scratch git repo and running unit tests, before copying that code into the plan. Since then I’ve been back to vibing. I lose overnight runs but gain sanity.
