Part of why these things feel "not fit for purpose" is that they don't include the things Simon has spent three years learning? (I know someone else who's doing multi-LLM development where he uses job-specialty descriptions for each "team member" that lets them spend context on different aspects of the problem; it's a fascinating exercise to watch, but it feels even more like "if this is how the tools should be used, why don't they just work that way"?)
