There is natural incentive for engineers working on a project to keep Claude skills up to date. I cannot say the same for general documentation.

But maybe not for long. When we get long-running AIs, the knowledge locked inside the AI's thinking might supplant docs once again. Like if you had an engineer working at your company for a long time and knowing everything. With all the problems that implies, of course.

That's the weird best thing about LLMs - there is finally incentive for projects to create documentation, CLIs, tests, and well organized modular codebases, since LLMs fall flat on their face without these things!
