ClassFile API's documentation has not been updated significantly since its initial preview. There are many details of the API that can be clarified, typos corrected, links added, and details noted, among other improvements.

This is an umbrella task; since this has a massive scale, the actual improvements will happen in subtasks dedicated for each package (main package, attributes, components, constantpool, instructions)

The tasks are strictly doc-only; any change to implementation and the derived specification updates will belong to their own issues.
