CBValidation and CBWire are not bundled with Coldbox. They are separate modules.
You can find their Forgebox links here:
The human friendly docs for each can be found here:
To my knowledge, the cbwire and cbvalidation modules do not have the same type of api docs that Coldbox has. However, their respective codebases are significantly smaller, so if you are curious about method arguments and such, you might have good luck checking out the source code on Github here:
Both repos are well documented and have plenty of code comments to help guide you.
