I figured it out. Originally posted in cdnusers.org by AshCan
As promised I have attached a zip file containing an example ConceptHDL Skill routine to this string. The zip file contains everything you need to implement the Skill routine.
This routine defines a Concept command called roomprop. When the command is executed the user is prompted for a value of a ROOM property that is to be attached to each component instance on the current schematic page. The user enters a string. The properties are added to the component bodies.
The routine is intentionally simple. It's main purpose is to provide a clear and well explained example who how to create and implement a Concept Skill program.
To implement with CDS_SITE:
Place the files concepthdl.scr, concepthdl_cmd.txt and concepthdl_menu.txt at $CDS_SITE/cdssetup/concept.
Place the files roomprop.il, roompropStartup.il, and stdAccess.il, at $CDS_SITE/cdssetup/fet/skill/context.
Start ConceptHDL and observe that there is a new tab on the menu called Custom Skill. RMB on that tab and note there is exactly one selection "Add Room Properties". Click this and follow the command instructions in the ConceptHDL console.
