For out-of-the-box Sakai, the help files for most core tools are delivered from Indiana University's Knowledge Base repository. These documents also appear in the Sakai KB, which is updated dynamically; the help files within Sakai, by contrast, are cached, and so may not match the content of the most recent version of any given document.
The help files for most contrib tools are not pulled from IU's repository, but are written by the schools who develop the tools. Exact processes for revising them may vary.
