while the phalcon-devtools is a really helpful package, the generated model classes are not IDE friendly.
I've had a project where we needed a custom generator, it's a bit messy, but the generated classes are properly annotated with docblocks.
Here is an outsourced package version of it: https://github.com/lajosbencz/phalcon-model-generator
I'd love to see something like this (proper dockblocks) in a new devtools release!
EDIT: We only tested it with PHPStorm
