Read uncharitably, yeah. But you're making a big assumption that the writing of spec wasn't driven by the developer, checked by developer, adjusted by developer. Rewritten when incorrect, etc.

One way to do this is to do the thinking yourself, tell it what you want it to do specifically and... get it to write a spec. You get to read what it thinks it needs to do, and then adjust or rewrite parts manually before handing off to an agent to implement. It depends on task size of course - if small or simple enough, no spec necessary.
It's a common pattern to hand off to a good instruction following model - and a fast one if possible. Gemini 3 Flash is very good at following a decent spec for example. But Sonnet is also fine.

Agree. Some things just aren't worth chasing at the moment. For example, in native mobile app development, it's still almost impossible to get accurate idiomatic UI that makes use of native components properly and adheres to HIG etc
this is my workflow, converse with it to write a spec. I'm reviewing the spec myself. Ask it to trace out how it would implement it. I know the codebase because it was originally written mostly by hand. Correct it with my best practices. Have it challenge my assumptions and read the code to do so. then it s usually good enough to go on it's on. the beauty of having a well defined spec is that once it's done, I can have another agent review it and it generates good feedback if it deviates from the spec at all.
I'm unsure if this is actually faster than me writing it myself, but it certainly expends less mental energy for me personally.
The real gains I'm getting are with debugging prod systems, where normally I would have to touch five different interfaces to track down an issue, I've just encompassed it all within an mcp and direct my agent on the debugging steps(check these logs, check this in the db, etc)
