My pet peeve is auto-generated documentation from configuration files or source code. It is absolutely useless and I would rather prefer no documentation than auto-generated.
Some time ago Swagger (nowadays OpenAPI) got really popular and many projects "had an API" and pointed users to their green autogenerated API documentation clusterfuck. When time went on this green page would become an indicator for me, that the project does not work and I should be very sceptical - I am sure there are projects that do it better, but for me no-content auto-generated documentation is a real code smell.
